Review Outline Defining Operations Forecasting Supply Chain Management
Productivity Quality Timeliness Flexibility Innovation
5
How do Firms Add Value? Greater Flexibility Greater Productivity
Greater variety Customization for customer needs / desires Useful Innovation Features, technology Better performance New capabilities Often unrecognized Greater Productivity Lower costs and expenses Lower prices for the customer Higher Quality Better performance Greater durability, reliability, aesthetics, ... Better Timeliness Faster response and turnaround On-time delivery, meet promises
6
Key Point Usable information must be captured and organized in a way that managers can understand how much value has been added.
7
Forecasts are usually wrong Forecasts should contain error measure
Forecasting Basics Forecasts are usually wrong Forecasts should contain error measure Aggregate forecasts are more accurate The longer the horizon, the lower the accuracy
8
Qualitative - Subjective
Forecasting Basics Qualitative - Subjective Expertise Based The “Sage” Sales Force Customer Surveys
9
Quantitative – Objective
Forecasting Basics Quantitative – Objective Causal Models Time Series Models
10
Forecasting - Causal Models
Use when historical data are available and when the relationship between the dependent (Y) and independent variable(s) (X) can be identified Causal methods are good at predicting turning points in demand and for longer range forecasting Principal Tool: Regression Analysis
11
Forecasting - Time Series Models
Prediction based exclusively on previously observed values General Idea: Detect Patterns! Short Term Demand Prediction Prevalent Tool In Operations Understand the players
12
Random Trend Seasonality Cyclic Time Series Patterns No Pattern
Linear (default) or Nonlinear Seasonality Repetition at Fixed Intervals Cyclic Long Term Economy Understand the players
13
What is a Supply Chain? A supply chain consists of all stages involved, directly or indirectly, in fulfilling customer requests The entire process from point of origin (raw materials) to point of consumption (final products bought by customers) A network (interdependent system) of facilities including materials supply from suppliers transformation of materials to (inventories of) semi-finished and finished products distribution of finished products to customers
14
Material/Product Flow
A Typical Supply Chain Information Flow Supplier Manufacturer Distributor Retailer Customer Material/Product Flow Value-Added Services Funds Flow
15
Now, What is a Supply Chain
SYST 4050 Slides Flow of products and services from Suppliers Raw materials manufacturers Intermediate products manufacturers End product manufacturers Distributors and wholesalers Retailers Customer Connected through transportation, information, and exchanges of funds Supplier Manufacturer Distributor Retailer Customer Chapter 1
16
Every facility that impacts costs need to be considered
Key Observations Every facility that impacts costs need to be considered Suppliers’ suppliers Customers’ customers Efficiency and cost-effectiveness throughout the system is required System level approach
17
Conflicting Objectives
SYST 4050 Slides Manufacturer Distributor Retailer Customer Large production batches Low inventory Few DCs Few stores Low inventory Little variety Close to DCs Convenience Short lead time Large variety of products Large shipments Chapter 1
18
Contemporary Supply Chains
Holy grail for SCM has been high speed and low cost For success, supply chains must also be: Agile Adaptable Aligned
19
Agility Objectives Methods
Repond to short-term changes in demand or supply quickly; handle external disruptions smoothly Methods Promote flow of information Develop collaborative relationships Design for postponement Build inventory buffers of inexpensive components Have a dependable logistics system or partner Draw up contingency plans; train crisis mgmt teams
20
Adaptability Objectives Methods
Adjust supply chain’s design to meet structural shifts in markets; modify supply network to strategies, products, technologies Methods Monitor world for new bases and markets Use intermediaries for suppliers & logistics Evaluate needs of end customer Create flexible product designs Identify technology and product life cycles
21
Alignment Objective Methods Create incentives for better performance
Exchange information and knowledge freely with vendors and customers Lay down roles, tasks, and responsibilities for suppliers and customers Equitably share risks, costs, and gains of improvement initiatives
22
Supply Chain Management Lessons
Effective SCM is a major driver of corporate (and national) competitiveness Supply chains are complex networks that must be managed carefully for success Supply chains must be an integral part of an effective operations strategy Arms-length relationships up & down the chain are becoming more collaborative Fundamental question: How can we create value for customers with our supply chain structures?
23
Competing with Productivity
Inputs: labor, materials, capital, … Outputs: goods, services
24
Factor Productivity Measures
Single Factor Productivity (SFP) Multi-Factor Productivity (MFP) Also, Total Factor Productivity (TFP)
25
Single Factor Productivity
Measures increase in productivity in relation to a single factor of production Labor, materials, capital, … Productivity = Output / Single Input Example: Output Labor Period units hrs Period hrs Productivity 10.0 units / hour 10.6 units / hour
26
Single Factor Limitations
Problem: too easy to substitute factors Company purchases casting and machines them Decides to purchase pre-machined parts Lays off skilled workers, sells machines Output remains constant, labor reduced Labor productivity up 5% (!) BUT: pre-machined parts cost 20% more SO: material productivity declines by 20% (!!)
27
Multi-Factor Productivity
Measures increased in productivity from all relevant factors of production Productivity (MFP) = all outputs / all factor inputs Example: product sales + internal services MFP Index = labor + material + services + depreciation + investment MFP Index 4.94% Increase
28
Multifactor Limitations
Issues affecting MFP measurement Inflation, currency exchange gains (losses) Depreciation, inventory valuation Product mix changes, choice of base period, output measures ... Theoretically interesting Difficult in practice…
29
How to Improve Productivity?
Specialization Better Work Practices and Automation Learning Economies of Scale
30
Specialization Improvement in a worker’s dexterity
Ability to do a task, resulting from a worker’s concentration on one or a few tasks. Saving in time typically lost in changing from one task (or group of tasks) to another. When workers do not specialize, time is lost from physically relocating to the new task and from adapting, or orienting, oneself to the new task. Concentration on a few tasks The Candy Factory Increases the likelihood of discovering easier and better methods Adam Smith, Wealth of Nations, 1776
31
Better Work Practices and Automation
Work smarter, not harder Scientific Management Early 20th Century Reaction to management problems of the industrial revolution Organized approach to improving labor productivity Standard methods, standard times “Time and motion” studies Championed by Fredrick Taylor, Frank and Lillian Gilbreth, others
32
Take-Aways Productivity improvement is a central concern of operations
Many ways to drive productivity Productivity improvement is a major driver of local and national wealth Various forms of measurement exist Single factor, total factor, … Measuring productivity in a firm Effective, accurate, simple Productivity is a critical component of value Key to improving standards of living A stern taskmaster
33
The Value Equation
34
Why Quality is Critical
Quality: Quality is the single most important thing you can work on to improve the effectiveness of your company. It's as simple as that. Things just cascade when you get control of your quality. John Young, CEO Hewlett Packard
35
Eight Dimensions of Quality
1. Performance The primary operating characteristics of the product or service. 2. Features The characteristics that supplement the basic functioning of the product or service. 3. Reliability Probability of the product or service failing within a specified period of time. 4. Conformance The degree to which a product or service meets acknowledged standards David Garvin, “Competing on the Eight Dimensions of Quality,” Harvard Business Review, Nov-Dec 1987
36
Eight Dimensions of Quality
5. Durability A measure of product life (both technical and economic). 6. Serviceability The speed, courtesy, competence, and ease of repair or recovery. 7. Aesthetics How a product or service looks, feels, sounds, tastes, or smells. 8. Perceived Quality Various tangible and intangible aspects of the product from which quality is inferred. David Garvin, “Competing on the Eight Dimensions of Quality,” Harvard Business Review, Nov-Dec 1987
37
Quality Costs Prevention costs: process/product design, training, vendor relations; Appraisal costs: quality audits, statistical quality control; Correction costs (internal failure): yield losses, rework charges; Recovery costs (external failure): returns, repairs, lost business.
38
What is Six Sigma? A measure of quality that strives for near perfection. Disciplined, data-driven approach to eliminating defects Scope From manufacturing to transactions From products to services Constantly striving for improvement Or else, loose ground to your competitors
39
Benefits of Six Sigma When Properly Applied General Electric
Reduce costs Increase revenues Develop your work force Provide a common corporate language and methodology General Electric Estimates benefits of ~$10 billion during first five years of implementation
40
Timeliness Sources of competitive advantage Lead time strategies Lean operations / JIT
41
Examples of Time Competition
Overnight package delivery Web-based information retrieval Online shopping, banking, and ecommerce Self-checkout at grocery Airline check-in Lift ticket scanners (ski resorts) Fast food, ready-to-heat meals Fashion industry Your examples…
42
Lead Time & Time Competition
Speed often is measured as: Quickness—measured by the mean Reliability—measured in terms of range and shape of the lead time distribution Lead time Important determinate of “speed” Lead time means several things Important to define exactly
43
Lead Time Strategies Engineer to Order Make to Order Assemble to Order
Designed to customer specification Make to Order Standard design, produced only upon order Assemble to Order Subassemblies produced, assembled upon order Make to Stock Finished product made prior to order
44
Just-in-Time JIT Operations Goal of Lean Systems: SIMPLIFY!
Produce only what is needed only when it is needed! Goal of Lean Systems: SIMPLIFY! Reduce inventories; Reduce setup times; Reduce information flows; Fewer, more reliable suppliers; Design products for manufacturability Reduce WASTE of all types! Russell & Taylor, Operations Management 3/e, Prentice-Hall, 2000
45
Unnecessary processes Inventory Motion and activity Defects
Sources of Waste Overproduction Waiting time Transportation Unnecessary processes Inventory Motion and activity Defects Russell & Taylor, Operations Management 3/e, Prentice-Hall, 2000
46
Reduce Inventory Produce in small lots
Eliminate space to store inventory Don’t overproduce to increase utilization and efficiency Better planning & forecasting Produce to actual demand Improve quality SHOW AMAZON.COM VIDEO
47
Lead time design opportunities Apply lean operations principles
Take Aways Time Powerful competitive force Often difficult to duplicate Lead time design opportunities Apply lean operations principles Reduce and eliminate waste Focus on value-adding processes Move from push to pull
48
Operations Flexibility
Types of Flexibility Mass Customization Pitfalls of Flexibility Driving Flexibility
49
Operations Flexibility
Flex’i*bil’i*ty: capable and adaptable to change. Perspective of the producer: Flexibility Perspective of the customer: Responsiveness
50
Like Quality, flexibility is not one-dimensional
Types of Flexibility Like Quality, flexibility is not one-dimensional 1. Mix Flexibility 2. Changeover Flexibility 3. Modification Flexibility 4. Volume Flexibility 5. Rerouting/Program Flexibility 6. Resource Flexibility
51
Mass Customization Delivering unique services in large quantities Manufacturing unique products in large quantities Offering customized services & products at (near) commodity prices Customization varies from cosmetic to structural
52
Pitfalls of Flexibility
Focus vs. flexibility Specialists vs. generalists Cost/flexibility trade-offs Flexibility for whom and what? When does the market reward flexibility? Customization/responsiveness squeeze
53
Flexibility has multiple dimensions
Take-Aways Flexibility has multiple dimensions Must strategically understand which are most important, and those that are less so Flexibility involves process design, product design, sourcing design Processes carefully married w/ products To provide appropriate flexibility Product / process matrix can help
54
Innovation Product vs. Process Innovation Managing for Innovation Theories of Innovation Patterns of Innovation Technological Forecasting
55
Managing for Innovation – Necessary Conditions
Innovative People Motivated to challenge constraints Socioeconomic Incentives Potential for wealth, fame, honor Diversity and Tolerance Penalties for challenging status quo not excessive Moykr, The Lever of Riches, 1990.
56
Barriers to Innovation
Intrinsic Barriers Uncertainty Fear of failure Requires array of talents Managerial Barriers Emphasis on maintaining order and discipline Risk aversion Reward systems which discourage uncertainty Competition for resources Institutional Barriers Treat to careers and status Territorial competition Hard work!
57
Take-Aways Innovation Technology
Promote necessary conditions, mitigate barriers Paradigms are powerful barriers We are in the middle of a tech revolution Technology Technological forecasting is difficult if not impossible S-Curve analysis helpful Beware disruptive innovation
58
What is The Internet? Internet is network on which the “web” is built
A series of tubes Scalable and distributed
59
How does the web work? Distributed Scalable No central traffic control
Multiple paths Links can be removed
