1 Standardized Work

2 Implementation Goal Anyone responsible for implementing and using Standardized Work will gain an appreciation for Standardized Work by learning: WHAT it is HOW it fits into the lean system WHY it can help in your daily job performance

3 Objectives Define Standardized Work
State the reasons and benefits for implementing Standardized Work Compare and contrast current work performance to Standardized Work performance Identify barriers to implementing Standardized Work and develop ways to remove them Understand and learn how to develop Standardized Work

4 1. Standardized Work Defined

5 What is it ? Work conditions, methods, and procedures that allow consistently repeatable results. Work-group generated Guided by documentation Starting point for Problem Solving Foundation for continuous improvement

6 History of Standardized Work
Based on proven U.S. military methods Incorporated by T. Ohno during the 1950’s at Toyota Part of Standardization, which is the foundation of Toyota Production System

7 “I don’t care how you get the job done, just do it.”
Old Paradigm “I don’t care how you get the job done, just do it.”

8 “Everyone does the job the same way each time.”
New Paradigm “Everyone does the job the same way each time.” The Process not the Person Consistent working sequence, cycle time and standard in-process stock regardless of which team member is performing the job. A proper method of problem solving is to repeatedly ask “Why?” something has occurred until you can get to a root cause of the problem.

9 Traditional vs. Standardized Work
Traditional Work Reacts to fires Searches for things Processes designed without input from staff Work is equipment- centered Uses a variety of individual methods Produces inconsistent results Standardized Work Prevents problems Finds things easily Processes designed by staff & supervisors Work is human-centered Follows and improves the standard process Produces consistent results

10 Standardized Work Allows for…
Worksite Management: Abnormal situations can be easily identified Problem solving can occur based on the discrepancy from the Standard Efficient training that produces operators who perform to the Standard Continuous Improvement: Identification of waste in the process Team members can suggest improvements

11 Standardized Work Ensures…
Built-in Quality at every process in the system. Just-in-Time processing The next process is provided with the right product and/or service, at the right time, in the right quantity

12 Standardized Work Summary
Four Main Advantages Prevents Over Processing (Waste) Ensures Quality Requirements Lowers/Stabilizes Cost Establishes Normal vs. Abnormal Criteria

13 2. Standardized Work Pre-requisites

14 Pre-Requisites Repeatable Human Motion Reliable Equipment
Quality Incoming Materials and/or Supplies Accurate Information – On Time

15 3. Standardized Work Components

16 Three Components of Standardized Work
Takt Time Work sequence Standard In-process stock

17 Takt Time

18 Takt Time… Sets the pace Is….
The time allowed to complete one procedure Based on available time and demand Computed and adjusted as demand changes

19 Takt Time Formula TT = Available Time Demand

20 Daily Available Time Total daily operating time: EXAMPLE:
The total time to treat the demand MINUS the scheduled downtime EXAMPLE: ED department runs 24 hours per day Total available time in a day – 1440 minutes No scheduled downtime Daily Available Time = 1440 minutes

21 The total processing requirement EXAMPLE:
Daily Demand Rate The total processing requirement EXAMPLE: ED department is treating patients at the rate of 3,000 per month. Based on 30 days per month, patients must be treated per day. Daily Processing Requirement = Patient Takt Time = 3,000 pts./month 30 days/month = 100 pts./day 1440 mins/day 100 pts./day = 14.4 mins/pt. Takt Time = 14.4

22 Work Sequence

23 Work Sequence Is… The repetitive performance of work elements that produce quality in an efficient manner: Work sequence can be work performed at multiple processes or multiple elements at a single process.

24 Example

25 4. Standardized Work Forms

26 Standardized Work Forms
Time Study Sheet Standardized Work Chart or Spaghetti Diagram Standardized Work Combination Table Standardized Work Sheet Job Instruction Training Sheet

27 Time Study Start and stop point identified for accurate and consistent timing Time for each individual element captured Time given to operator is based on the average time of 10 separate studies per element Worker effort rated if standard data not used Person with knowledge of area review current state assessment to check for accuracy

38 5. Additional Uses for Standardized Work

39 Standardized Work Uses
Safety Reduces ergonomic burden Highlights potential hazards Training Training New Team Members Cross-Training for Flexibility Problem Solving Pin Pointing Discrepancies Continuous Improvement Work Balancing Kaizen Activities

40 Job Instruction and Training

41 Purpose of Job Instruction
Transfer the needed knowledge and skills to the team member so that Standardized work is performed resulting in the work being completed: Safely Correctly Consistently

42 Job Instruction Training Sheet
Major Steps WHAT to do Discreet value- added actions Simple, Correct, Consistent Key Points HOW to do it Specific motion or information needed to perform the major step correctly Safety is always a key point Reasons WHY to do it Effects on: Safety Ergonomics Gov’t.

48 Seven Wastes

49 What is Lean? “A process of continuously identifying, reducing and eliminating waste (non-value added activity)” “Waste is defined as anything other than the minimum amount of equipment, materials, parts, space and worker's time which are absolutely essential to add value to the product” Shoichiro Toyoda President, Toyota

50 Lean is… A system of thinking, not just a set of tools A learning system which encourages staff to perform better in technical operations, which, in turn, increases process performance. The relentless pursuit of waste!!

51 7 Wastes + 1 Correction/Rework Movement Waiting Inventory
Dirty instruments in Assembly, damaged instruments, bent instruments, aborted sterrad cycle Movement Searching for paperwork, walking long distance to printer or scanner, getting wrap, obtaining containers Waiting Waiting for scopes and light cords, waiting on sterile carts, waiting on cases to start Inventory Extra sets and instruments, excessive amounts of filters or supplies, extra containers Overproduction Cleaning and Assembly of several sets not needed for OR, Pulling OR cases by supplies days ahead of time Transportation Searching for sterile, stat, or distribution carts; extra trips for decon rounds, distribution of sets Over-Processing Second signature of assembled sets, two or more indicators in a set, extra instruments in sets People Not using people’s abilities to their fullest potential, improper training and education of staff

52 Causes of Waste Organizational issues Operational issues
Lack of workplace organization Lack of training Inconsistent performance measures Poor production planning and scheduling Operational issues Long setup time Lack of Preventive Maintenance Layout (distance) Work methods Incapable processes Supplier quality

53 Why Reduce Waste? Makes Work Safer Faster Cheaper Easier

54 How Do We Reduce Waste ? Eliminate: Combine: Reduce: Simplify:
Workstations, Complexity Combine: Workstations, Processes Reduce: Content, Complexity Simplify: Process

55 Motion Kaizen

56 Kai = Change Zen = for the Better
Definition of Kaizen Kai = Change Zen = for the Better “A change for the better” or “continuous improvement”

57 Kaizen Events… Targeted Improvement Document Standardized Work
Study through observation to improve Document and train new Standardized Work to maintain the improvement

58 Instructions for Work Kaizen
Objectives In order to Kaizen, we look at the worker’s motions. The goal is not to make the individual tasks faster, but to develop smooth and repetitive motions with little waste. Priority of Work Kaizen vs. Equipment Kaizen: Work Kaizen can be done in little time Work Kaizen can be done with little investment If Kaizens are unsuccessful, other Kaizens can be easily tried

59 Kaizen Example: - Current State Lab Process
