In a minute will have _______________, President of Buzz Electronics Enterprise, give you a brief description of the company and your job assignment for the first production round.”After the first production round, we will be alternating between lecture and production rounds. As you can see we will have three more lectures and two more production rounds. Throughout the lectures we will be discussing various lean manufacturing principles and applying those principles to the different rounds.”“At the end of the day, we will summarize and have time to answer any remaining questions.”Transition: “As I mentioned earlier, we have a simulation to demonstrate the different concepts you will be learning. You have been recruited to be operators for Buzz Electronics Enterprises. Before we start working, _______________ wanted to give you a brief orientation to Buzz Electronics and hand out the job assignments.
9Lean Overview and Simulation Orientation to Buzz Electronics Enterprises (BEE)Note to President: Use an authoritative and powerful tone. Be very possessive, using ‘my’, ‘mine,’ and ‘I’, but never ‘our’ or ‘we.’ Use warnings and gold stars or ‘at-a-boys’ for reprimanding and rewarding people who ask questions or answer questions or if you think someone should be rewarded. You should be dressed as a ‘stuffy’ and uptight executive.“Good morning.”“As _____________ (instructor) mentioned, my name is ____________ and I am the President of Buzz Electronics Enterprises, also known as BEE. I built this company from the ground - up. It is my pride and joy. I feel and of course all the management feel the same way, right ____________ (instructor), that everything is running smoothly and the best it will ever be.Your sole purpose today is to work for me. Yesterday’s crew was released because they couldn’t get results. My HR Manager has assured me that this crew will be different. I am expecting a lot out of you and after today’s orientation you will be well trained and start working without any problems.”“I hope you are all ready to work and to work hard to make me some money. Our motto at Buzz Electronics Enterprises is “Show me the Money.”Transition: “Before we start working I am going to give you an in-depth orientation on my products, my operations, and your jobs. By the end of this orientation you should be knowledgeable of my products and your job function. Please no questions. It’s very distracting to me and a waste of your time since you are not getting paid for this training. Ok, let’s get started.”
10Buzz Electronics Enterprises Product Catalog“First I would like to discuss the products that my company produces. They are highly sophisticated electronic boards used in the security industry and of course have been recognized by Consumer Reports as being the best. I have my salesperson sell to the every day users, commercial and to sophisticated users such as NASA and federal agencies. Besides our company motto: “Show me the money.” I also stress Quality and On-time delivery.”Transition: “The first product I will discuss is the blue avenger. I hope you all are paying attention because this is important information and I am not going to repeat myself.”
11Basic model for every day use The Blue Avenger “The blue avenger is our bread and butter. This product is used by our customers for basic, everyday use in home security systems. The residential market is the primary end user for the Blue Avenger. This is the most popular model. What do you expect since I developed and designed it? It’s the higher volume product in my line. It’s simple, but practical, and sells easily on the market.Transition: “The next product is a more recent version of the blue avenger with added features.”
12Industrial model for commercial use The Red Devil “The red devil, as I mentioned, is a more updated model. It was my ‘pet’ project about 5 years ago. It’s a lower volume line for my business but a higher margin product. It’s more expensive but it offers more features. The red devil is primarily used in retail and commercial sites and occasionally in higher income residential areas like the one I live in.”Transition: “The last model is the best of all! It’s going to put Buzz Electronics on the map.”
13for the sophisticated user The Gold BuzzPremium modelfor thesophisticated user“This model was designed specifically for users that have sophisticated security systems such as NASA, certain government agencies, and other high tech industries. I feel, no actually I know, this model is going to take us over the top in sales. The Gold Buzz Model is going to put this company on the map. Whoever builds this model you better make sure to pay attention and make it right.”Transition: “____________ (instructor), went to some silly seminar about how we should show our employees the cost of the product and from that seminar suggested incorporating this slide into our orientation. Personally, I don’t think it’s any of your business but I try listen to my employees once in awhile.”
14The Bottom Line The Blue Avenger The Red Devil The Gold Buzz Sells for $20Materials cost $5.00The Red DevilSells for $30Materials cost $7.50The Gold BuzzSells for $50Materials cost $10.00Labor Cost = $7.50/person/shiftFacilities Cost = $10.00/table/shift“I want to make sure you all understand that this information is highly confidential and proprietary. Therefore I better not hear you talk about this on the floor or with your families or any of your friends.”Read slide.We’ve done a lot of thinking about the layout and processes in this plant. I believe that our costs are at the lowest we can get them.Transition: Now I think you are ready for your job assignments.

Very good. I can see you are all catching on. Maybe I won’t have to fire you like I did the last group.”“I have put together work instructions that tell you exactly what to do for each job function. There should be no confusion at all.”To Instructor: “Have these people taken a competency test?”“I would like to make sure that everyone can assemble. Let’s read the top row together. A, B, C, D, E. Ok. Sounds pretty good. Now let’s read the column with the numbers: 1,2, 3, 4, 5. Good. I think this group may work out.”“Just to make sure you all understand, let’s look at this example. The instructions say to insert a spring into C3. Therefore I look at the top and find the C column, count down to three and insert spring. Nothing to it. “Point to A2. “________(attendee) what is the location?” Good.Transition: “Let me take a minute to talk to you about the components for the three different models.”345C-3

We have springs, jumpers, resistors (red and green), diodes, LED’s, Buzzers and Transistors. The Diodes and the LED’s must be inserted in a certain direction because they are polar – like batteries, they have a positive and a negative side. Both have a black stripe which must face a certain direction. Read your instruction carefully when installing those two parts.”Transition: “For even more detail I have some slides that show you what components are used for each model.”

We have made these instructions as simple as possible we even included a picture of how to tell if the board is good or not.”Transition: “Great, everyone understand what they are doing and how to make the board. Just a couple of more slides and we start working.”
21Inserting ComponentsTo insert components easily, bend the spring backwards and slip the wire in between the coils.DO NOT wrap the wires around the spring.
22The Red Devil Production Batching 6 per batch 4 per batch The Gold The Blue Avenger6 per batchThe Red Devil4 per batch“One item I wanted to make sure I mentioned is the standard lot size. I have done sophisticated and extensive number crunching to figure out the best standard lot size. I’ve looked at the setup required and determined that its most efficient for me to build my Blue Avengers in batches of 6, my Red Devils in batches of 4 and my Gold Buzz in batches of 1.”Transition: “Another point to go over with you is our scheduling process.”The GoldBuzzHand-crafted 1-at-a-time
23BEE Production Scheduling Process ShipmentstocustomersCustomerorders(demand)CustomerorderformsProductionforecastFactoryorderformsFinishedGoodsWarehouse“I schedule my factory by first having my Production Scheduler release Factory Orders according to my forecast. These Factory Order forms trigger the kitting of parts and production of my boards, which go to Finished Goods.”“At the same time, my Sales Representative is taking Customer Orders and generating Customer Order Forms. These forms are given to my warehouse to ship product to my customer.”Transition: “I want to take a minute an emphasize our strategic goals.”
24BEE Customer Service Targets Promisedshipmentstocustomers4 minutes after orderBlue5 minutes after orderRedGold6 minutes after order“As I mentioned earlier, on-time delivery is extremely important to me. Because it is so important to me, I have mandated that every time a customer calls us with an order we give them a promise date. For Blue Avengers, it’s 4 minutes after the order has been placed, Red Devil is 5 minutes after the order has been placed and for Gold Buzz it’s 6 minutes after the order has been placed. If I tell someone a specific time and date I expect it to happen. If we don’t deliver on time, the late shipments are discounted by 30%. Do you think this would make me very happy?Wait for a response from the group.“Of course not, the last group didn’t make me very happy. That is why I fired them all.”“Yeah, and another thing, no jumping orders or cherry picking of orders. Everything has to be done First-in, first-out.”Transition: “I sure hope you were all paying attention because I expect great results in the first round. To make sure we have success I have a couple of rules to follow.”All orders are filled “first-in, first-out”Late shipments are discounted by 30%
25BEE Company Policies All shifts are 20 minutes. Keep busy at all times.Yell if you need parts.Handle all parts first in-first out.Only the material handler can move parts.Stay at your workstation.The boss is always right!Read slide.“Now what is our motto?” Wait for group to reply. “Right, Show me the Money!”Transition: “Let’s get to work, everything is set up in the other room.”
26Round 1Let’s Get To Work!!Instructor reviews the results with the group.“____________(President), are you ready to see the results for Round #1?”“Ok, but maybe you better sit down for this.”
27ResultsNote to Instructor/Facilitator: To enter data, make sure scoreboardNew.xls is in computer, make sure PowerPoint presentation is normal view. Go to Edit, then click on Links. A window should open, Highlight the file scoreboardNew.xls, Click Open Source. Excel Spreadsheet named Scoreboard will open. Enter data ONLY in the spreadsheet titled as DATA ENTRY. Calculations will be done automatically. Verify results in the spreadsheet titled as SCOREBOARD. NEVER CHANGE ANY INFO ON THIS SHEET; THIS IS THE SHEET WITH ALL THE FORMULAS. Save excel file after you entered information. Go back to LO file, make sure to be in normal view. Click once onto spreadsheet on slide (should see white boxes highlighting object). After spreadsheet is highlighted right click the mouse. Click onto “Update Link,” you should see that spreadsheet updated. Page down to second spreadsheet and highlight object, right click, update link. You need to update each slide every time you make a change in the excel file.Note to instructor: For the first round, explain the results and calculations without the president so that everyone has a understanding of the metrics. Also don’t forget to have people fill out the student scoreboards. Put the formulations for the calculations on a flipchart to hang up to remind everyone how the calculations were derived.“The first item we measured was manufacturing cycle time or lead-time. This number was calculated by our IEs. Remember the yellow post-it notes on the boards? That is what the IE’s calculated the cycle time from; how long did take the part to get through the whole process, from production scheduler to warehouse.”“For the first round, our manufacturing cycle time was _____ for the Blue Avenger, ____ for the Red Devil, and ____ for Gold Buzz.”“The next metric we are using is on-time delivery. This is calculated by the number of units on-time divided by demand. On-time percentage for the Blue Avenger was _____% on time, for Red Devils ____% on-time and for Gold Buzz we had ____% on-time. Those percentages are not good. Remember every time we had a late order, that order was discounted by 30%.”“We also started with WIP (work-in-process) on the line. Some people may call this ‘wetting the line’. For Blue we had 18 units throughout the process, Red Devil we had 8 pieces and Gold 2 pieces. We started with some WIP, but we ended the round with A LOT of WIP. For Blue Avengers we had ____, Red Devil ____, and for Gold Buzz___.”Transition: “Now we need to see what type of financial impact this had on BEE. How much money do you think we made?”
28Results“Before we talk about profits, we need to look at our sales dollars and total costs.”“For the Blue Avenger we ended up with ____units sold, that includes late and on-time, Red Devil ____ units sold, and Gold Buzz ____ unit(s) sold.The sales are calculated on the # of units shipped x sales price. Our sales dollars generated equaled _____. ”Question: Does anyone remember the sales prices for the different models?” Wait for a response. “Right, Blue sold for $20, Red Devils sold for $30, and Gold sold for $50.Next, we need to know the total cost to produce the items. This consists of material, labor and overhead. The material costs are calculated by adding the number of completed units x the cost to make them. If we refer to our manual (slide #14), we know it costs $5.00 in materials for the Blue, Red costs $7, and Gold Buzz materials cost ”“Next we need to calculate the direct labor costs. This is calculated by adding up the number of employees x the pay rate, which is $7.50 / shift.”“We also need to calculate the cost for overhead, or the facility costs, which is the number of tables times the cost of tables. We discussed earlier that each table costs $10.00.”“We add up the cost for materials, labor, facilities and the cost of late shipments to get the total cost. For Round one our total cost was ____.”“To calculate the profit we have to subtract the total costs from sales $. For round one our profits were ____.”Call the President in to review the results. Read through the results and have the President make shocking remarks about the results.“___________ (instructor), I would like to share with the group some lean manufacturing principles that I feel may help increase the profits for BEE. Is that ok with you?”President:“Well, I am willing to try anything to make more money. These principles better work or you will have to hire some new people. President leaves classroom to help with simulation.Transition for Instructor:” We have a lot of work ahead of us. Wed better get started.”
29Lean Manufacturing Agenda A Manufacturing BackgroundLean Manufacturing Foundation:Waste ReductionLean Manufacturing:Basic ConceptsFurther Concepts“I mentioned earlier that we would rotate the lecture portion with the simulation rounds. The agenda for the different lectures is listed here:”“First we will discuss the history of manufacturing and the definitions for lean, then discuss the different types of wastes that you find in traditional manufacturing plants. We’ll also discuss the impact of having a good housekeeping culture, the differences between traditional vs. lean layouts, and the benefits of point-of-use storage, setup time reduction, and batch size reduction. We’ll also talk about using takt time to balance the line.”“After the 2nd round, we’ll talk about visual controls, quality at the source, standardized work, workforce and management practices, pull systems, and total productive maintenance.”Transition: “Before we start talking about a lean manufacturer, let’s talk about traditional manufacturers.”
30Profile of a Traditional Manufacturer Characteristics of your operation:“What do you think were some characteristics of the first round at Buzz Electronics?”Note: Use a flipchart or whiteboard to capture characteristics.Transition: “Great! Some of these points are definitely characteristics of a traditional company but let me give you some more examples.”
31Profile of a Traditional Manufacturer Inventory built to forecastInventory used to satisfy customer demandExcessive work in process (WIP)Large batch sizesFocused on a small pieceCost-cutting focusDepartment/work center efficiency measures“A traditional manufacturer typically builds to a forecast, which means that if a customer calls, product is pulled from inventory to satisfy the customer. Also, if you walk in a traditional manufacturing plant you usually see a lot of work-in-process.”Question: “Why do you think traditional manufacturers build so much to inventory and have a lot of WIP?”“A lot of times the reason companies build WIP and inventory is because they are hiding or trying to make up for a process problem. For example a machine has a lot of downtime. Therefore, whenever it’s able to run, the production manager runs the heck out of it. Another big reason is if someone is measuring the machine efficiencies. It looks a lot better on the books if we keep running the machine even if we do not need the parts. ”“Another characteristic is large batch sizes. This is sometimes caused by having long setups and low confidence level in the ability to complete the work without scrap or on time.”Question: “ How many of you have said to yourself, ‘If it takes four hours to setup this machine, I am going to run the whole week’s or month’s worth so that I don’t have to setup up for this product again.’?”“You know, if I had 4 hours setup I would probably say the same thing. That is why later we will discuss the importance of setup time reduction.”“A big characteristic of a traditional manufacturer is that departments work independently of each other and there is a lot of finger pointing done. Also, department managers are focused solely on reducing cost in their areas and not concerned about what effect the changes they are making will have on other areas downstream or upstream.”Transition: ” Let’s talk about how manufacturers evolved these characteristics.”
32Manufacturing History CustomerRequirements1800’s1900’s1700’sTime2000• High volumes/High Inventories• Cost cutting focus/Efficiency• Mass production/Automation• Assembly lines/Divided laborTRADITIONAL• Custom-made, one at a time• Highly skilled craftsperson• Non-standardized work• Non-interchangeable partsCRAFT“If we take a look at the history of manufacturing, we have two distinct periods. The first is the era of craft manufacturing, which is a time before the industrial revolution. Characteristics during the craft era were highly skilled workers using hand tools, with no standardization. Also these manufacturers were titled as masters in there profession because they went through a rigorous training program of being an apprentice, journeyman, and then finally a master.”“Once the industrial revolution started in England around 1733, this moved manufacturers into a more modern world; we can classify this era as the mass production era. Or we will refer to these manufacturers as the traditional manufacturers. During this period, new inventions were changing the way of life. Historians state that one of the most influential inventors during the American industrial revolution was Eli Whitney, who presented the U.S. government with a new way to manufacturer a certain commodity.”Question: “Does anyone know what that product was?”“Right, Eli Whitney developed the concept of building muskets with machines instead of building muskets by hand. Eli Whitney’s idea of interchangeable parts was a brand new concept which would begin the industrial revolution in America. Obviously, during the late 18th century and through the 20th century there were many inventions that contributed the success of manufacturers. The next person who is most famous for mass production is Henry Ford. He didn’t invent the idea of mass production, but he took it to the next level.”“Henry Ford was an entrepreneur and a visionary. He wanted to manufacturer cars that were large enough for the family, constructed of good materials and had such a low price that everyone making a good salary would be able to own a car. So how did Henry Ford make this happen? He used his ingenuity to take the assembly-line method of production to new heights of productivity and efficiency. He did this by standardizing work and divided labor into classified workers. Unfortunately, other characteristics of the traditional manufacturer were high volumes to offset costs and standard costing focused on efficiencies of machinery, which promoted high inventories.”“Henry Ford did an excellent job sharing information with other companies. Unfortunately, he became complacent with the Model T and refused to innovate and produce more of what customers wanted. That is what caused him to fall from the top.”Transition: “Understanding the history of manufacturing allows us to understand the requirements of manufacturing today.”
33Global competition is driving Customers to seek and expect: Manufacturing TodayGlobal competition is drivingCustomers to seek and expect:SpeedQualityAndFlexibilityAt theLowest PricesQuestion: Does anyone know what Henry Ford’s famous saying was regarding the Model T?“Right, you can have any color that you want as long as its black. How would you like it if a salesperson said that to you? I know if a salesman said that to me I would say thank you very much but no thanks. As customers we expect companies to have the product available when we want it, with the different options and colors we want, good quality and most of all with the lowest price.”“As consumers we are more educated than ever but that means we also expect more. This need for more for less has started the change in how companies manufacturer products.”Note: Use Flip Chart. Write on the flipchart Profit + Cost = Selling Price on one line and then leave some space and write Selling Price – Cost = Profit. Make sure to cover Selling Price – Cost = Profit until you talk about it.“Traditional Manufacturing is sometimes referred to as a seller’s market. Companies would determine how much profit they wanted, which, plus the cost, equaled the selling price. It’s easy to apply this concept if you have a company that is a monopoly or during the introduction of new technology. For example, cell phones. When cell phones were first introduced they were selling for $2500. Now you can get some cell phones free when you buy the service.”“As we move into the next generation of manufacturing and more educated customers, the past cost equation (Profit plua Cost equals selling price) doesn’t work. As consumers we set the selling price; no longer do companies set the price except for new technology. Now we have the selling price minus the cost equals profits. This is called the buyer’s market.”Question: “If this is the new equation, selling price minus cost equals profit, how does a company increase their profits?”“Right, through reducing their costs.”Transition: “Since we have moved to a Buyer’s market, we need to figure out a new approach to manufacturing.”

As I mentioned earlier, we were in the Seller’s Market. If they made it, someone bought the product.”“During the 50’s and 60’s, it was difficult for the Europeans or Japanese because they were rebuilding from the war. Actually the Europeans grabbed onto the ideas that Henry Ford developed and started to become mass producers. The Japanese also tried these concepts but just were not successful. Therefore, they started “tweaking” methods of mass production to develop a system that worked for them. Especially since they didn’t have the large market the US had at the time during the 50’s and 60’s, they needed to become more competitive and flexible to meet consumer demands. The most famous Japanese manufacturer to develop a new approach was Toyota. But it took this company about 30 to 40 years to become a leader in the automotive industry. Another contributing factor was that they had the help of two famous Qualititians, Juran and Demming. These two qualititians tried to educate Americans during the 50’s on the importance of quality, but no would listen. They went to Asia and the Japanese grabbed hold of these principles and ran with them. ““The major time that consumers really asked for something specific or challenged the manufacturers was during the 70’s or the oil crisis. Consumers wanted smaller and more fuel efficient cars. Consumers started noticing foreign manufacturers that met their needs and started buying their products. This started the move toward a Buyer’s Market. Not until the mid-80’s did the US manufacturers notice that there was a different approach to manufacturing products and that is really when companies started evolving into lean manufacturing.Transition: “So what is lean manufacturing?”
35What is Lean Manufacturing? concept by TPS; terminology by Womackan umbrella for good business practicesa strategy for decreasing the time between order placement AND delivery of goods or services“As I mentioned earlier, Toyota took the concepts from mass manufacturing and started tweaking the process to create something called the Toyota Production System. This approach utilized less human effort, smaller and more flexible machinery, a flexible workforce and kept smaller amounts of inventory on-hand.”“The name Lean Manufacturing was actually coined by James Womack. James Womack conducted a study using graduate students from MIT (Mass. Institute of Technology). The purpose of this study was to gather data to prove or disprove which type of manufacturing system was the best. From this data, James Womack proved that the companies that implemented this system were more profitable, quicker to respond to market changes, had higher delivery ratings and produced what the customer wanted.”Transition: “Lean is defined many ways but we have adopted the definition from APICS.”
36NIST Definition A systematic approach to identifying and eliminating waste(non-value added activities)through continuous improvementby flowing the productat the pull of the customerin pursuit of perfection.-- The MEP Lean Network“Part of our funding comes from the National Institute of Standards and Technology's (NIST) Manufacturing Extension Partnership (MEP) program. EDI is the MEP center for Georgia.”“The definition that is used by this group is the concentration on eliminating the non-value added activities to create flow of the product by the pull of the customer in pursuit of perfection.”Transition: “The last definition is the one that Georgia Tech has created.”
37“Where’s the bottleneck in my company?” Lean ThinkingLean Thinking begins with the SYSTEM“A group of interacting, interrelated, or interdependent elements forming a complex whole.”American Heritage Dictionary, rd Edition“Where’s the bottleneck in my company?”“A Lean Thinker’s view is to look at a company as a holistic system. Everything interacting, interrelated or interdependent, which forms a complex whole.”“When implementing lean you don’t just focus on one particular area on the manufacturing shop floor, but look at the whole system and approach the areas that are bottlenecks or problematic areas that hold you back from accomplishing your goals.”Transition: “Lean does not have to be complex. Always remember the ultimate goal is eliminating wastes.”
38Lean Manufacturing Agenda A Manufacturing BackgroundLean Manufacturing Foundation:Waste ReductionLean Manufacturing:Basic ConceptsFurther ConceptsTransition Slide:“Let’s move on to the next bullet on our agenda, Waste Reduction. As I mentioned, Lean focuses on reducing wastes.”
39Foundation of Lean Manufacturing Waste identification and reductionValue adding vs. non-value adding5SLayout/FlowPoint-of-Use StorageSetup Time ReductionBatch Size Reduction“In the next couple of minutes we are going to discuss identification of waste, VA and NVA, Housekeeping and layout and flow.”Transition:“First let’s talk about Waste.”
40What’s Stopping Industry? Waste!!!NOTE: Bring up the title first, ask the question, then bring up the answer.Question: “ What is stopping you from getting rid of the duplication and redundancy in your processes.”Note: Take a minute to get feedback and record on flipchart.Transition: “The best place to start is to define waste.”
41Waste Defined Does NOT add value Does NOT result in conformance to customer specsCustomer would NOT pay for it!“Waste is anything that does not add value to the process or any activity that does not conform to customer’s specification. Most importantly, waste is any activity that the customer is not willing to pay for.”Transition: “To make it easier to identify waste we have two key definitions.”
42Value Added Transform materials to product Meets customer expectations Customer would pay for it!“Our first definition is value-added activities. Value-Added activities are any activities that transform the materials into products to meet the customer’s expectations. It’s easy to think of it as what the customer is willing to pay for.”Question: During the last round, what would you classify as VA?“Right, actually inserting springs or diodes or LED or resistors into the board.”Transition: “Great, now that we understand the definition of value-added activities, we need to understand the definition of non-value added activities.”
43Non-Value Added Does not add value Is not necessary Should be eliminated, simplified, reduced, or integrated“The opposite of value-added activities is non-value added activities. These are activities that take time and resources but do not add value to the product. For example, waiting for material to be delivered to an operation.Question: “Can you name some NVA that you saw during the last round?“Right, waiting for orders, waiting for an operation, getting up from the workstation to get instructions, movement of material are just a few examples of NVA activities. Most importantly, these are the activities that you want to eliminate from your processes.”Transition: “We can further classify the wastes so that we can find them easily in your company.”
44Studying Waste VALUE ADDED Drilling Machining Cutting Welding Assembling PartsPaintingNON-VALUEADDEDStoringSet - upsInspectingMovingConveyingWaitingDecidingReworkingTravelingTransportingPaperwork“Remember, value-added activities are activities that transform the materials into the end product and that the customer is willing to pay for.”Question: “What would be some examples of VA in your facilities?” Write answers on Flipchart.“Exactly, drilling would be VA, actual cutting of the part in a machine.”“Non-value added activities are activities that do not add value but take up time, resources and money. Examples of that are the eight types of waste that we just talked about.”Question: “Can anyone, without looking at your book, name off the eight types of wastes?”“Great, sometimes we have activities that we classify as non-value added but are difficult to totally eliminate. For example, transportation. You still need to get the materials from the receiving dock to the line. If you can’t eliminate this step, the question should be how can you reduce it as much as possible.”Transition: “Let’s take another look at what could be value-added and non-value added activities.”NON-VALUE ADDED BUT ESSENTIAL
45Where is Waste? Overproducing Defects - Rework or Scrap Inventory Waiting of parts/people/machines/ paperworkTransportation of parts, people, paperExtra ProcessingMotion of people, machinesUnused employee ideas“Overproducing is when you make more, or move ahead or faster than the next process. Companies typically overproduce to hide the ‘rocks’ in the water. For example, long setup times or wanting to avoid setups, low confidence level in machinery, and justification of an expensive machinery. This is really one of the worst type of wastes because it leads to excessive inventories, excessive transportation, and potential for scrap.”“Defects is another type of waste because it wastes materials, and both person and machine hours making bad product, inspecting bad product and segregating it from good, and correcting bad product.“Another type of waste is inventory. Inventory is a waste if you are holding excessive amounts of WIP between processes, raw materials, and finished goods. All this extra inventory causes companies to use cash to fund the interest of these materials or products. This is called carrying cost. Inventory is also difficult to reduce because holding extra inventories protects companies from uncertainties and inefficiencies such as long setup times, unpredictable suppliers, and lack of flexibility.“Waiting for parts, people, machines, and paperwork is a big waste. It delays the time that we can complete a process and causes frustrations.”“Unnecessary transportation causes us to spend time on money moving inventory around the plant multiple times versus the least amount.”“Extra-processing or over-processing are activities that are done over and above the customer requirements or unnecessary steps that do not add value. For example, a customer asked for a widget with two holes but we engineered the part to have three. Another example may be washing parts because they became dirty sitting in inventory.”“Motion is a waste when a person or a machine has a movement that does not add value to the product. For example, walking 5 steps to get material versus having the material at the point of use.”“The last type of waste is the worst of all because it is not utilizing employees’ ideas. The employees who have worked or work in a particular area have the answers to the problems or know where the waste is in the process. We need to make sure to tap into those resources.”Transition: “We have focused primarily on wastes on the manufacturing floor but wastes are throughout plants.”
46Non-Value Adding activities Value Adding activities Waste in Your PlantProduct Leadtime95%5%Traditional FocusLean Focus“Waste is everywhere on the shop floor, in the administrative areas, everywhere. All these wastes cause extra time to produce the product (known as lead-time) to be excessive. If we followed a product through a plant from the time the raw materials were received to the time the product was shipped, we would see a lot of non-value added activities occurring. That is what the red represents: non-value added activities such as materials sitting in inventory, parts being moved multiple times, waiting for materials, etc. The green represents the value added activities. As you can see the value added activities are only little slivers of time.“If we grouped all the non-value added activities, it would total to 95% of the total time to produce the product. And if we grouped all the value added activities together it would be only 5% of the total time. So what does that mean in real numbers? Let’s say the time that we receive materials to the time to ship took 10 days. Only half a day of these 10 days is spent transforming the materials into the final product. Wow! All the other time is the non-value added activities.”Question: “If we look back over time, where has management or support staff focused to improve the process?”“Right, on the value-added activities or making the machines run faster. The Lean approach tackles the non-value added activities or the 95% of waste that is taking up all the time.”Transition: “The first step to reducing waste is having an organized workplace.”Note to Instructor: If you have time, develop a process flow for the red devils. Have the group give approximate times for travel, queue time, and assembly of one piece. Add up the value added time and it should be a small percentage of the 20 minutes. Use 20 minutes because typically no one gets a red devil out in less than 20 minutes. You can even prepare for this by having your IE’s take times of activities during the first round.Note to Instructor: Another option is to draw on a flipchart a circle and showing that 12% in VA (pie) and 88% is NVA which represents Toyota’s non-value added / value added makeup. And stress that they have been trying to reduce waste for years and continuing driving up their VA%’s.Non-Value Adding activitiesValue Adding activities
47Lean Manufacturing Agenda Lean BackgroundLean Manufacturing Tools 1-6Lean Manufacturing Tools 7-12How to Implement LeanTransition Slide:“Let’s move on to the next bullet on our agenda, Lean Manufacturing Tools. As I mentioned, Lean focuses on reducing wastes and these tools help.”
48Lean Manufacturing Tools Layout/FlowPoint-of-Use StorageSetup Time ReductionBatch Size ReductionUsing Takt Time to Balance“In the next couple of minutes we are going to discuss READ TOPICS.”Transition:“First let’s talk about 5S, which is good housekeeping practices.”
495SA safe, clean, neat arrangement of the workplace which provides a specific location for everything and eliminates anything not required.“5S is a 5-step philosophy that can be defined as the foundation that creates a culture for Lean Manufacturing. Good housekeeping exposes the problems and allows you to find the root cause of a problem faster. For example, if there is a puddle of oil and housekeeping is not done a regular basis, how would someone know the source of the oil leak? They wouldn’t, but if the area is cleaned every day, you have a greater chance of catching the oil leak. Also, good housekeeping improves employee morale, safety, and quality of the parts.”Transition: “Let’s define the five steps in 5S.”
50A Place for Everything5S results in a place for everything and everything in its place.What is missing from the usual industrial environment? CLUTTER!Note how easy it is to find something out of place. It’s immediately visible, without having to know anything about production operations.
515S Workplace Organization SortSet in OrderShineStandardizeSustainQuestion: “Can I see a raise of hands of how many keep a clean and orderly work area or have a manufacturing floor that is clean?”“Well, if you have to look for anything, then it is waste.”“The first step is to sort items that you use and that you don’t use. The items that you do not use, throw away or store in remote location. When in doubt, throw it out.”“The second step is to take what is left and to organize the tools in designated locations or “set in order.” For example, lines on the floor, signs hung from the ceiling, tool boards. If there is not a designated space for something, then it should not be in the work area. Everything should have a place and everything in its place.”“The third step is to give the area a good cleaning, “shine,” and then instill cleaning on a daily basis to maintain the area.”“The fourth step is to standardize the process throughout the company. For example, develop cleaning checklists, make work assignments and develop safety checklists.”“The last step is to develop an infrastructure to sustain the organization and develop management’s commitment by using 5S auditing boards. Audit an area to take action if the area is not maintained or congratulate if the area has sustained the improvements.”Transition: “Can you think of some more benefits of good housekeeping?” Wait for some answers.
52Benefits of 5S Removes safety hazards Eliminates waste caused by disorderSearching for parts and toolsHighlights abnormal situationsWorking with poorly-maintained equipmentIncreases employee morale and prideImpresses current/potential customers“Good housekeeping helps to remove safety hazards and eliminates clutter in the area that could cause someone to search for tools. Also, good housekeeping highlights problems faster. I mentioned the oil leak earlier. Another example is if an area is marked off for a specific amount of WIP and the area has more or less that would tell me that we have an unbalanced line.”Question: “How many people want to work in a dirty area?”“I know I don’t want to. If people have a clean and safe work environment, morale increases and so does pride in the company.”“Also, another benefit is impressing potential customers.”Question: “What would you think of a potential supplier if their plant was dirty and unorganized?”I probably wouldn’t have the highest level of confidence.Transition: “Good housekeeping is an important way to help you uncover wastes and improve your processes.”
53Layout/FlowThe physical positioning of processes, departments, equipment, and work areasto optimize an organization’s effectiveness in achieving its operating objectives.“The next concept that we will discuss before the next round is layout and flow.”“The definition is the physical positioning of processes, departments, equipments and work areas to achieve the most efficient flow. Ultimately, you want to do this throughout the plant.”Transition : “Did you think the layout in the last round had the most efficient flow?”
54Traditional Layout/Flow Departmental Specialty“Right, the layout was not the best. It caused excess material handling, poor communications and excessive WIP.”“Many manufacturing operations are not too different than Buzz Electronics. Traditional manufacturers use a functional layout like this one. Machines performing similar functions are grouped together. Physical departments often form around these functions. The arrows depict material movement throughout the facility.”“A traditional layout creates its own chaos. For example, due to the separation of department, a complex schedule is created. A schedule must be developed for each department in an attempt to ensure that departments are working on the “right part at the right time.” How often do you think that happens? The more complex the system becomes, the more difficult it is to manage and the less responsive it becomes. So what is created are hot orders.Question: “ How many have a system for ‘hot’ orders?”“Other results of a traditional layout are large lot sizes and excessive material handling. Of course, it doesn’t make sense to make only ten and then have someone transport 10 parts across the plant.”“Another common problem is poor communication between departments regarding issues. People are physically separated from those with whom they need to regularly communicate to resolve problems or concerns.”“Also specialized workers were created due to the separation of departments which limits the flexibility of the workforce.”Transition: “The traditional type of layout causes plants to work in departmental silos, causing department supervisors to focus on their specific areas and not the total product flow.”
55Lean Layout/Flow Product Focus “To eliminate the unnecessary wastes with the traditional/functional layout, Lean focuses on organizing a plant layout by product. For example, all the machinery that deals with product A would be grouped together and the same for the remaining products.Question: “What is the advantage of grouping machinery/processes by product families?” Allow time for answers.“Some benefits are flexibility, responsiveness, reduction in lead-time, reduction in inventories, smaller lot sizes, and cross training of employees, to name just a few.”Transition: Next, let’s talk about point-of-use storage.”
56Point-of-Use Storage Raw materials stored where used Frequent, small shipments from vendorsRequires trustworthy workforceSimplifies physical inventory tracking“Point-of-use-storage means that you locate the raw materials needed at the point of use. This concept eliminates the non-value added activities in handling the raw materials excessively. It is very important when redesigning a layout that you consider all the materials used so that you have a storage place that is in close proximity.”Question: “How could we have applied this concept during the simulation?”“Right, we could have stored the springs at the spring assembly workstation, the resistors at that workstation and so on.”Transition: “Let’s take a look at additional benefits of point-of-use-storage.”
57Point-of-Use Storage of Parts This tilted shelf is used to provide all the parts needed for an assembly area.Note the 5S aspects: labels, dividers, yellow marks for maximum and red for minimum inventory.All the parts needed are right at the work area.You might also see point-of-use storage using shipping containers. This works especially well with small parts.
58Printer Cart with Paper Storage This is a rolling printer cart with four storage drawers for different paper types, such as plain, letterhead, pre-punched, and legal.A controlled amount of replacement paper is always within easy reach. (Photographed at the Georgia Tech Regional Office in Macon).
59Benefits of Point-of-Use Storage Reduces material handling requirementsEasier to determine raw material needsReduces waiting for parts“As I mentioned, point-of-use storage reduces the material handling of parts. Also, because the materials are stored at the workstation, operators and management have a better idea of the usage and when materials need to be ordered. Traditionally, materials are stored in the warehouse and you would only know you didn’t have materials when you went to pull the raw materials for the next job. Point-of-use-storage allows you to become more proactive and helps eliminate unnecessary material shortages. It also eliminates most of waiting for parts. ”Transition: “Let’s talk about additional tools that we need to give the workforce to create a culture of continuous improvement.”
60Setup TimeThe time from the last good product of the previous run to the first consistently good product of the next run.Gathering necessary itemsExchanging partsPositioning partsMaking adjustments“The definition for setup time is the time from the last good product of the previous run to the first consistently good product of the next run. Setup time includes gathering necessary items, exchanging parts, positioning parts, and making adjustments. An easy way to relate setup to time reduction is to car racing.”Question: “Where do car racers usually lose the race?”“Right. In the pit. Therefore, race car drivers have had a group of people study the process and reduce the pit-stop time to seconds. We can relate this to our production floor. Where do we lose the manufacturing race? Well, if we have setups that take longer than 10 minutes.”“Setup time is important and a necessity. If you reduce your batch sizes and you do not reduce your setup time, you will have a lot of frustrations and problems. Reducing your setup time allows you the flexibility to produce what the customer needs rather than planning how to avoid setups.”Transition: “Let’s look at some more benefits for reducing setup time.”
61Benefits of Setup Time Reduction Increases overall capacityImproves machine uptimeReduces start-up wasteMakes smaller batches economicalReduces lead time“As I mentioned, by reducing your setup time, you have more flexibility. You also gain more capacity, and will have the ability to perform more setups without hindering the production schedule. It also improves quality through reducing start-up waste. Another important benefit is that it will reduce your lead-time.”Transition: “The next concept that we are going to discuss is Batch Size Reduction.”
62Batch Size Reduction …Producing smaller amounts between runs Kathy, reducing batch size was a great idea!Is it me or does this seem inefficient?Large Batches are a result of operations being set up to produce or work in departments or batches. The concept over the past 50 years or so has been to output a product or service by dividing the work into departments (silos). This worked well when there wasn’t much variety and you were producing one product but market demands began to push new products and versions, while manufacturing stayed the same.Today companies are producing batches (order quantities) that they feel are economically sound. (Balance between WIP levels, downtime on equipment due to Set-Ups, and throughput).There is a balance, but in general the more you can move toward a “One-Piece Flow” concept the better the flow of material. This means lower costs.Notice: we just discussed Set-Up Reduction prior to talking about Batch Size Reduction. There is a reason for this.Question: Why do you think it is important to understand and utilize Setup Reduction prior to Batch Size Reduction?That’s right! Reducing Batch Sizes (order quantity sizes) means that you will have more production run changes or more set-ups. Set-ups are non-value added time and so unless you reduce the amount of time that each set-up takes you are likely to reduce your throughput when applying Batch size reduction.One-Piece FlowLarge Batch Size
63Benefits of Batch Size Reduction Reduces overall lead timeReduced WIP and inventory costsLess impact from quality problemsEasier to maintain FIFO/lot controlGreater flexibilityLess reliance on forecasts“Reducing your batch sizes helps you reduce the amount of WIP on the floor, which equals less capital or inventory. It also helps reduce your lead-time.”“By reducing your batch size, you reduce your lead-time because now you have reduced the WIP that sometimes hides problems and cause delays. Now you are able to find the bottlenecks in your process quicker to allow product to flow. Also, smaller batch sizes help maintain first-in-first-out and lot control. And as I mentioned and showed through the example, smaller batch sizes control the number of defects. This allows greater flexibility and less reliance on forecasts.”“If you reduce your batch size, it is extremely important to reduce your setup time or smaller batch sizes will not be effective.”Transition: “The last concept we will discuss before the next production round is the use of takt time to balance operations.”
64Takt TimeSpeed at which a product must be manufactured in order to satisfy customer demandCalculated Value“Takt is a German word that means beat. That is exactly what takt time is--the ‘beat’ at which the customer buys the product. Takt time is the rate at which product must be produced to meet the customer’s requirements. It is a calculated value that takes into consideration the time available for work and customer demand.”Transition: “Let’s take a look at the takt time calculation.”
65= = Takt Time Calculation Time Available Takt Time Demand Takt Time Example:Time Available = 8 hours per dayDemand = 100 widgets per day“The calculation for takt time is the available amount of time divided by demand.”“This example uses uses 8 hours available, that means that an operator has 8 hours to work. It does not include scheduled breaks, lunch or other scheduled downtime, such as cleanup times. Available time on a shift is often less than 8 hours because of this.”“The daily demand for this example is 100 widgets.”“8 hours divided by 100 widgets equals 0.08 hours. If you take 0.08 hours times 60, it gives you the time in minutes, 4.8.”“Great, but what does this all mean? Well, if you remember that takt time is the rate at which the customer is buying the product, that means we need to produce at that same rate. This tells us that the customer is buying a product every 4.8 minutes. Therefore, we need to make a product every 4.8 minutes.”Question: Use flipchart. “For example, if my takt time is 4.8 minutes and I produce at a rate of 2 minutes. What am I doing?”Right, I am over-producing and making inventory.Question: Use flipchart. “If my takt time stayed the same, 4.8 minutes and I produced at a rate of 6 minutes. What is happening?”“Exactly, I will have a ton of late orders and not able to meet the customer’s demand. The goal is obviously to balance the operations to the takt time. It’s extremely important to be flexible and adjust if the takt time does change.”Transition: “Let’s take a closer look at using takt time.”TaktTime=8 hours100 widgets0.08 hours4.8 minutes
66Takt Time/ Cycle Time Bar Chart 184.108.40.206.9.6.3Takt time = 1.35MinutesThis is an example of a Takt time/Cycle time bar chart.Cycle time is shown for each operator using the bars.Takt time is shown with the dotted line.The idea is to shift operations until all operators are working within the takt time. This eliminates bottlenecks and balances operations.If takt time changes (and it will vary), you should calculate the new takt time and compare it again to operations.OP
67Benefits of Takt Time Indicates what is required of process Provides target for productionPaces production to demandUsed to determine resource needsUsed to balance production process“The biggest benefit of takt time is understanding your customers’ requirements and when they need the product. This allows you to balance your operations accordingly, to make sure you can meet your customer demands and meet your production targets. As mentioned before, you are working at a steady pace versus a ‘hurry up and wait’ mentality. Using takt time can help you determine the number of operators you may need or the number of pieces of equipment.”“Takt time is an essential tool to use when balancing lines and operating efficiently.”Transition: “We have covered 5S, Layout/flow, Point-of-use storage, setup time reduction, batch size reduction, and using takt time. Do you think we can brainstorm using these concepts to make the next round better?”
68How can Round 1 be improved? QuestionHow can Round 1 be improved?“Remember we only produced ____ units, our on-time delivery was ____ and our profits were ____. What can we do to improve those measurables? My job is on the line because ______ expects these metrics to improve.”Note to Instructor: Have topics listed on a flip chart prepared beforehand. Record related ideas on the flipchart. Let the group know that they will have 5 minutes to brainstorm the ideas. Suggest that they call out ideas and you will add them to the flipchart. At the end of 5 minutes (use the timer), spend no more than another 10 minutes going through the ideas to see if the group wants to implement them. If group wants to change layout, try and help them organize their thoughts so they are not wasting time or eliminating people.“All these ideas are great but we have to get permission from the big ‘Kahuna’ before we can implement them.”Note to President:Principles discussed: Craft/Traditional/Lean Manufacturing, VA & NVA, 8 Types of Waste, 5S, Layout/Flow, Point-of-Use Storage, Setup time Reduction, Batch Size Reduction, and Takt Time.If the group comes up with an idea, pressure them to either explain the concept or the benefit of implementing that idea.Changes allowed for Round #2:No Instruction Crib No KittersNew layout Eliminate Production reportsNo WIP Area Fix Packaging Machine (SUR)No Material Handler Balance operations from takt time/cycle timeThe group will suggest visual controls, or other items that will be discussed next. Make up a story but you can’t have them implement those items until they are discussed in the lecture.
69Question (Cont’d)Note to Instructor: Read ideas to president, or have people quickly justify their ideas individually.“I have been reading in that brochure you gave me, _______, that I should learn to trust and listen to my employees. So, I am going to give you this next opportunity to make some money. But realize if we don’t have profits, I can’t afford to have you working for me anymore. Let’s get to work.”Transition: “I sure hope that _________(president) attends that seminar. He/she can really use the help.”
70Round 2 Let’s Get To Work!! Instructor: “________, we made improvements but I still think you should sit down for these results.”

I am going to review that brochure you gave me about how to manage people effectively and get some lean training myself. It does seem to be working, but we have to do more!”Transition/Instructor: “Thank you ______, I promise I won’t let you down.”

74Lean Manufacturing Agenda Lean BackgroundLean Manufacturing Tools 1-6Lean Manufacturing Tools 7-12How to Implement Lean“We have some more lean manufacturing concepts to discuss, which might help us improve even more.”
75Lean Manufacturing Tools 7-12 Visual ControlsQuality at the sourceStandardized WorkWorkforce/management practicesPull Systems – Make to OrderTotal Productive Maintenance (TPM)Transition Slide:“During this lecture we will discuss visual controls, quality at the source, standardized work, workforce/management practices, pull systems, and total productive maintenance (or TPM).”
76Visual Controls Simple visual signals Efficient Self-regulating Worker managed“Visual controls should be simple. They should allow someone to walk into an area and have a immediate understanding of the situation or condition. If someone has to think about a visual control, it’s probably too complicated. Visual controls are efficient and should be low maintenance. Operators should be able to manage and change visual controls when necessary.”Transition: “When I think of visual controls I think of universal signs that everyone understands. When I have traveled to foreign countries, international visual signs are a must for me to get around.”
77Types of Visual Controls LightsCardsInventory“Visual controls can be in a form of a light. Some companies have installed lights to help identify machine status. A green light indicates the machine is running, a yellow light shows if a supervisor is needed, and a red light indicates the machine is not running.”“Cards such as kanban cards can be helpful to indicate when to produce more product, re-order points, etc.”“Inventory or raw materials may be stored in such a way to indicate that, when an item gets below a certain level, it’s time to re-order.”Transition: “The next slide has more examples of visual controls.”
78Types of Visual Controls Red ZoneYellow ZoneGreen ZonePart #ShaftStandard Pack: 100 pcs.Number of Signals: 10Part #ClutchStandard Pack: 30 pcs.Number of Signals: 15Information“Easy to recognize signals include a hazard symbol, a no-smoking symbol, and a control chart. Other signals include a kanban board and standard work instructions. Some easy ones to think of include a stop light, stop sign, and traffic signs, all of which must be understood immediately. Other visual controls I have seen are painted footprints to show the operator’s routine and shadow boards. Shadow boards outline the tools stored on the board, so when the tool is taken you know exactly what was taken and where it needs to be put back.”“Visual controls are meant to help simplify the situation and help the operations run smoothly.”Transition: “Let’s look at a few examples, then review the benefits of visual controls.”
79Visual Control in an Office Setting Most of us have seen this kind of board at one time or another.It visually signals whether someone is in their office or out.As long as people update the board on a regular basis, it saves time by not having to look for someone.
80Visual Control in a Factory In the aerospace industry, it’s critical that mechanics know where all their tools are to avoid foreign object damage.This is another type of “shadow board” to clearly and visually indicate when any tools are missing.
81Benefits of Visual Controls Immediate understanding of conditionImproved safety and housekeepingReduced potential defectsReduced work-in-processSelf-regulatingEasy to use“The biggest benefit of visual controls is that it allows someone an immediate understanding of an area or situation. For example, you may walk into a cell and immediately understand the operator’s routine because there are foot prints on the floor or a layout of the area indicating the operator’s routine.”“Another extremely important benefit is that visual controls can help you improve safety and housekeeping. Visual controls can help you do this by having a place for everything and everything in its place.”“Visual controls will help you control defects or highlight defects through pictures/jigs that you have put in place. And visual controls will help reduce your work-in-process because there is now a clearly marked space and accurate number of the maximum amount of WIP. If there is more WIP in that space than allowed, you know you have a problem.”“Most importantly, visual controls are self regulating and easy to use.”
82Pass Fail Quality at the Source Places responsibility for quality on the worker doing the jobPromotes doing the job right the first timePassFail“The next concept we will discuss is quality at the source. This means placing the responsibility for quality on the worker doing the job. A good motto to have is, “don’t make or pass bad parts on to the next process.” Actually, Quality is considered one of the pillars of Lean manufacturing. It is essential to have good quality parts because in a Lean environment making bad parts is a waste, as it consumes time and resources that could have been spent making good parts.”“For operators to take this responsibility, they must be given the tools and time to inspect the parts before passing the parts to the next operation.”Question: “In the last round who knew if the part was good or not?”“Right, the only person was the inspector and if it was bad, the rework person fixed the problem.”Ask the person who was the Reworker: “How did you rework the boards? And how easy was it?”Transition: “What do you think the benefits are from quality at the source?” Allow group time to give answers.
83Benefits of Quality at the Source Reduces need for reworkPrevents work on defective productSimplifies prevention and repair of defects“Exactly, not passing or not producing bad parts reduces the need for rework and prevents adding labor and materials to a defective part. Also, it’s easier to fix a problem at the source of assembly versus using someone with less expertise in the process. The goal should be to build quality into the product.”Transition: “The next concept that we are going to discuss is Standardized Work.”
84Standardized WorkWhere there is no Standard, there can be no Kaizen Masaaki ImaiThree Elements of Standard Operations:Standard Operations SheetCleanGrindTakt TimeWork SequenceStandard WIP12Machine4Read quotation by Masaaki Imai (Author of Kaizen)During WWII, skilled mechanics and machinists were sent to the battle fields, leaving behind men and women who were unfamiliar with the equipment and operation to backfill those positions. This possibly was the beginning of Standard Operations in JapanTPS - There are three components/elements of Standardize Work.Takt – The first standard is to determine is what is needed. What is the ultimate expectation in meeting the customers needs? This is the takt time, the “beat” at which the customer is buying the product.Work Sequence – Once Takt is determine, we still have a problem. There are differences in the way people & machines perform. Thus the need for defining a Standard Work Sequence. This will provide the benchmark for improvement to occur.Standard WIP – once a standard has been established for man and machines, we need to establish the standard for material. Specifically this is called Standard WIP.Make it Visible!653QADeburDrillTakt TimeCyc TimeStd WIPQuality ChkSafety Focus# of Emp4 min4 min= 62
85Why the Emphasis on Standardization? It is the foundation for continuous improvement (promotes Kaizen)Makes MBWA more effectiveBuilds trustImproves Training/Cross TrainingEncourages/provokes “How can this work even – better?” thinking among employeesPromotes team environmentRemember, your goal is to build a environment that will allow for ongoing improvement!! If you are going to “build” something, what do you need? You need a solid foundation. Making improvements to shop-floor operations that aren’t standardized is like building a house on sand instead of solid ground. Standardized Operations makes it easier to identify improvement as well as to carry forward those improvements throughout the facility (benchmark).As a supervisor, your job is to be on the floor as much as possible monitoring the operations; being available to identify and remove obstacles. This is frequently called WBWA or “management by walking around.” It is much easier to monitor something that is consistently done from work station to work station and from operator to operator.Visual standards builds trust between the operator and the supervisor as well as between other operators because of shared knowledge.It also makes cross-training easier, because there is a specific way to do a job. Think back to the training on bending the spring to insert components.If operators are doing the same job the same way from work station to work station, don’t you think that they would be more apt to identify a better way of doing things?Because everyone agrees on how to do a certain job, you have better communication, which means better teamwork!Continue to revise the standard; IMPROVE!!!
86Workforce Practices Cross-trained employees Multi-skilled workers Employee problem-solving teamsTeam-based cellsContinuous improvement philosophyThese require effective leadership, a culture change, and respect for the workforce!“Cross-trained and multi-skilled employees allow management to become flexible. People can be immediately moved where they are needed versus used to produce parts that are not needed.”Question: “Does anyone remember the last type of waste we discussed?”“Right, not using employee ideas. It is so important to listen to the employees. But we must also give them problem solving tools and techniques to make the improvements and help them sustain these improvements. By giving the employees these tools, they are more likely to solve the problems on their own, work in teams and develop a philosophy of continuous improvement.”Transition: “Let’s review in more depth the benefits of good workforce practices.”
87Benefits of Workforce Practices Increased morale and job securityQuicker response to schedule changesEfficient handling of problemsImproved communication, cooperation, and trustBetter understanding of the “big picture”Increased acceptance of management decisionsIncreased flexibility“As I mentioned earlier, by involving employees and giving them the tools they need, they will have a better outlook on the job. Also, employees and management will be able to respond quicker to changes or ‘hiccups’ in the process. This improves communication, cooperation, and trust because everyone understands the goal and targets they are working toward. I think a big advantage is that employees that solve problems and deal with management on a daily basis understand management decisions better and understand the ‘big picture’. This concept is essential to a successful implementation of lean.”Transition: “Now that we understand the benefits of having the workforce involved, what type of management support do we need?”
88Management Practices Must be a partnership NOT a quick fix Requires disciplineRequires senior management commitmentAvoids “yet another program” syndrome“We need a lot of help and support from management. Management needs to understand that Lean Manufacturing is not a quick fix. Remember, it took Toyota years to develop a system and they are still working at improving this approach. A disciplined approach is required.”“Also, if you look at the companies that have had the most success with Lean, they are companies that have commitment from senior management. That is a key factor. Senior management committed to lean understand that this is not another ‘flavor’ of the month but the next generation in manufacturing. Another key point to note is that Senior Management that understand Lean Manufacturing also understand that there are going to be some bumps in the road but they know that this is the best approach. Ultimately, it will make their company the best. Some great books to read about lean successes are Lean Thinking and Becoming Lean. “Transition: Let’s look at one the biggest wastes in manufacturing – work in process and inventory.
89The Waste of Work-in-Process Ties up capitalDecreases flexibilityIncreases opportunity for scrapRequires more physical spaceLowers customer satisfaction“Work-in-process, or WIP, ties up capital that could be used elsewhere, decreases production flexibility, increases the opportunity for scrap through obsolescence or damage, requires more physical space for storage and warehousing, and ultimately lowers customer satisfaction.”Transition: “So we’ve established that excessive WIP is a bad thing. Now let’s talk about how to control it.”
901 2 3 Push vs. Pull Systems Push System Schedules production based on forecastPull SystemEnd-of-line authorizes production to replace only what has been consumed123Product FlowSignal Flow“Before we talk about a Pull system, we need to talk about the traditional system, which is a push system. A push system is a replenishment system that has production and purchase orders initiated by projected demand. The push system continues to produce orders regardless of whether consumption is taking place or not. Also within this system, processes operate under the philosophy of ‘make as much as you can as fast as you can.’ The result of the push system is high inventories, large lot sizes, management by fire fighting, poor communication, moving materials multiple times, long lead-time and (due to the excessive inventories) a potential for obsolete or damaged parts.”“A pull system is driven by customer demand rather than a forecast. The customer pulls the product from the final process step. The final process then communicates through a signal to the previous operation that parts were used and need to be replenished. It’s a rippling effect because that process communicates to the previous process step they need more parts and so on. Also, this system works at a steady pace and does not produce until the next process needs a part.”Question: “ In the first round were you working in a push system or pull system?”Transition: “Definitively a push system. Let’s take a closer look at the characteristics of a push system.”
91Characteristics of a Push System “Have you ever been overstocked with parts or materials you didn’t need but short of items you needed desperately? This poor guy is getting a delivery he doesn’t need, but somebody somewhere has determined that he’s supposed to need it.“This frequently happens due to a number of characteristics common to push systems:”“First, the schedule is driven by what we predict will be needed, rather than actual demand.Managers tend to emphasize machine utilization. The goal is to produce as much as possible to cover overhead, regardless of market demand. The same thing happens with materials. The push to use raw materials generates lots of work-in-process, which increases throughput time.Long throughput and lack of flexibility make it hard to respond quickly to changes and special needsA push system takes more management effort to balance the line and keep the right product on track.”Transition: “A push system is driven by forecast and a pull system is driven by actual customer demand. Now, let’s take a look at characteristics of a pull system.”
92Characteristics of a Pull System “As I mentioned, in a pull system the customer is driving the pace of production. The pull system controls the WIP through Kanban cards or other types of signals. A kanban could represent one piece or a batch size. It is the amount of WIP that is needed to maintain a steady pace and buffer the delay in response time between processes. This minimizes the WIP and also exposes the problem areas faster. This creates an atmosphere that allows quick adjustment to customer changes or problems that may occur.”Instructor, ask the students: “So why are we looking at a picture of a woman shopping in a grocery store – what’s that got to do with manufacturing?”“What we now call Pull Systems in manufacturing were originally inspired by supermarkets. When Taiichi Ohno of Toyota visited the US in the 1950s, he marveled at the information flow used to keep supermarket shelves full, and adapted the concept of a customer choosing an item from a retail setting to manufacturing.”Transition: “What are some other advantages of a pull system?”
93Benefits of a Pull System Manufactures only what is neededImproves communication of customer needsProvides common system for moving materialEliminates scheduling complexitiesReduces lead time and WIPInventory counts quick and easyPull systems provide many benefits:The plant manufactures only the product needed by the customer, so excess inventory is reduced or eliminated.It improves internal communication of customer needs through visual controls.It provides a common system for moving material.Pull systems eliminate the need for complex scheduling by utilizing kanban cards or min/max levels.It reduces lead time and WIP.Inventory counts are completed quickly by counting the number of pull signals (or kanbans).“To summarize the benefits of Pull systems, you are only making what is needed which results in lower inventories, less WIP, reduced lead-times and flow created within the production line. By using a pull system, you will improve communications through the Kanban cards or the visual signals that alert a process that they need to start producing a part “Transition: “The next slide demonstrates a pull system with kanban cards.”
94X X X 1 2 3 How Does Pull Work? Signal Flow Product Flow Note to Instructor you will manually have to click through this slide.To help the group understand this concept, you may want to pull boards from the kit and have a visual demonstration with boards and kanban cards. Further explanation at this point eliminates some of the confusion in the last round.“If I click once, it demonstrates I am pulling material out of stock because I have a customer order. That leaves an ‘X’ or a kanban signal to operation #2 that #3 needs more parts. Operation #3 pulls the part from Operation #2 and that leaves an ‘X’ or kanban signal for Operation #2. Operation #2 pulls parts and Operation 1 now has an ‘X’ or kanban signaling that they need more materials.”“Just remember, a pull system is working to the customer demand, each operation is producing as parts are pulled. This means no building ahead and it may mean that an operation sits idle because the next process downstream has a longer cycle time. That’s ok because it highlights the bottlenecks and the need for improvements.”Transition: “The last lean technique we will cover is total productive maintenance.”
95Total Productive Maintenance Basic Principles:Lean production is not possible without highly reliable equipment.Proactive, productive maintenance eliminates equipment-related waste and improves equipment reliability.Proactive, productive maintenance is a shared responsibility.
96Benefits of TPM 2 - 5 Years: Unplanned downtime 50-60% Breakdown costs %Spare parts costs %Product defects %Lead times %On time deliveries %Review the results shown on this slide (taken from a survey of companies who have fully implemented TPM).Transition: Do you think we can improve Round 2 by incorporating the concepts that we just learned? Let’s brainstorm and see what ___________ will let us implement.
97How can Round 2 be improved? QuestionHow can Round 2 be improved?Note to Instructor: Have topics listed on a flip chart prepared beforehand. Improvement ideas in this section do not fit so readily into the categories, so just make a list on the flip chart. Let the group know that they will have 5 minutes to brainstorm the ideas. Suggest that they call out ideas and you will add them to the flipchart. At the end of 5 minutes (use the timer), spend no more than another 10 minutes going through the ideas to see if the group wants to implement them. If group wants to change layout again, try and help them organize their thoughts so they are not wasting time or eliminating people.During the brainstorming of possible improvements, introduce the use of a takt time/cycle time bar chart to help level the workload. If possible, use actual data the Industrial Engineers have collected during Round 2. Use a flip chart to demonstrate the bar chart. You may have to facilitate the discussion on leveling. This should take no more than 10 minutes even with questions and discussion.“__________, I think we have some great ideas that will definitely make a difference.”Note to President:Principles just learned: Visual Controls, Quality at the Source, Standardized Work, Workforce/management practices, Pull Systems, Total Productive MaintenanceChanges for round #3:Refine layout to cell configurationEliminate Production SchedulerUse visual templatesGold inspects own productEliminate ReworkerCross-trainingLeveling to remove bottleneck based on takt timeReduce batch size to oneIntroduce pull with kanban squares
98Question (Cont’d) Note to Instructor: Read ideas to president. “ You know, some of these ideas are really interesting. We sure need to see some improvement or we’ll be out of business.”NOTE: President announces export Gold boards, which will absorb any “excess” production. Be sure to be supportive of lean because you are seeing improvement.
99Round 3 Let’s Get To Work!! Instructor: NOTE: Intervals between the first 10 Customer Orders shorten in this Round so delivery can be faster.NOTE: Remind workers that as many Gold Buzz as they can complete can be exported immediately.“Great job everyone, we definitely made an improvement. Let’s take a look at the results.”

102Lean Manufacturing Agenda Lean BackgroundLean Manufacturing Tools 1-6Lean Manufacturing Tools 7-12How to Implement LeanTransition Slide:“We’ve discussed the background of manufacturing and a number of lean tools and techniques. Next, we’re going to discuss how to implement lean concepts within your company. But first, let’s do a quick review of the last concepts we learned.”
103Manufacturing History CustomerRequirements1800’s1900’s1700’sTime2000• Mass production /Automation• Assembly lines / Divided labor• High volumes / High Inventories• Cost cutting focus / EfficiencyTRADITIONAL• Reduced WIPReduced inventories• Multi-skilled workforce• Production based on demandLEAN• Custom-made, one at a time• Highly skilled craftsperson• Non-standardized work• Non-interchangeable partsCRAFT“We started with craft manufacturing, which had the characteristics of highly skilled workers but no standardization, and items were typically expensive. The industrial revolution moved us into the next phase, traditional or mass manufacturing. In a traditional company you would usually see high inventories, specialized labor, high volumes and a focus on machine or operator efficiencies. Lean manufacturing is the new generation. Lean manufacturers utilize employees to solve problems, have less WIP, shorter lead-times, and produces what the customer wants, which causes the company to have less inventory.”Transition: “Let’s take a closer look at the differences between Lean and Traditional Mfg.”
104Lean vs. Traditional LEAN Simple and visual Demand driven Inventory as neededRun by value addersSmall lot sizesMinimal lead timeTRADITIONALComplexForecast drivenExcessive inventoryOverhead runBatch productionLong lead time“Lean manufacturing stresses working ‘smarter versus harder’ and how we can solve problems with our brains and equipment that we have versus buying a new ‘cash hog.’ The biggest difference is that lean allows you to react to customer demand, where traditional manufacturers had so much inventory and were so focused on large batch sizes that if a change occurred, it was a nightmare. The change would cause frustration and a lot of extra cost.”Transition: “Most importantly, we need to think how lean effects a company versus a department.”
105Where Lean Applies Product Lead Time AdministrativeTotal QualityProduct DevelopmentMetrics“Lean Manufacturing is a holistic approach to eliminate waste throughout the whole system. Lean manufacturing is not limited to one department or the manufacturing shop floor. Lean concepts should be incorporated throughout the business from product development to shipping product out the door. ““Sometimes we try to focus on the shop floor because it is easier to see immediate results, but to become a Lean Enterprise you must eliminate all the wastes throughout your system.”“More importantly, don’t do projects just to say that you did a improvement project. Project implementation must be done with a logical and systematic approach. If not, what is going to happen is you will become discouraged and will not see the results, or you could potentially cause another area to have problems.”Transition: “So how do you get started with the implementation of lean?”OperationsSupply ChainInventory ManagementA holistic approach to eliminating waste in the entire system

109How to Get Lean by Cutting Waste Understand WHAT and WHERE waste existsMap value streamsMeasure each processIdentify non-value added activitiesCreate a PLAN to eliminate wasteIMPLEMENT plan to eliminate wasteMEASURE and review results, then REPEAT“First you need to understand and identify the waste. This can be done through value stream mapping. This process is looking at a product family from receiving of materials to shipping and the information flow that occurs. This allows you to analyze a situation and develop a plan.”“Next, develop a plan to eliminate waste that is aligned with your company’s strategic goals and objectives. Most importantly, get your executive management’s support and commitment.”“After you have a plan, don’t sit in a room and analyze when it would be best to get started. Just go out and start following your plan of projects and start implementing. Before you start implementing, though, always make sure you have a baseline to measure where you started and the improvement you have made. Repeat and repeat. I’ll tell you the first projects will be a mixture of results but you must continue to tweak projects to become a Lean Manufacturer/Enterprise. Remember, Toyota has been doing this for over 50 years and they have improvement events at least once a month to improve areas that they had a project on maybe 6 months ago. Never think that once you have a success or improvement that you can’t go back and improve. You must continually improve because as time changes so do customer requirements, employees, and so on. Remember to go for the base hits, not the home runs.”Transition: “Let’s review the building blocks of lean.”

The first one is that you had fun today and learned a great deal about lean manufacturing.”
112Ideas to Take Back Lean Manufacturing does work Gain buy-in from top managementForm a team to lead implementationBuild employee awareness and buy-in“Besides having a fun day, you learned that lean manufacturing principles do work and it can work in your company. Just be sure to take the time to understand how and to develop a plan.“As you are implementing lean, you need buy-in from top management. This is a must for a success implementation. Form a team to help develop an implementation plan and to follow through with the plan. Most companies that have implemented lean have involved everyone and have done a lot of communication regarding what is lean, what the strategy is, how they fit into the picture, how they will be involved, and upper management commitment.”Transition: “If you want to learn more about lean or how to get started we have a few suggestions.”
