6. 6 METHODOLOGY OVERVIEW
7. 7 LEAN OVERVIEW § Lean is a management philosophy derived from the Toyota Production System (TPS) developed between 1948 and 1975 and has since been applied with great success in the services industry in recent decades § In “Lean Thinking”, published in 2003, James P. Womack and Daniel T. Jones introduced five fundamental Lean Principles. § Value § Value Stream § Flow § Pull § Perfection
8. 8 Activity – Best way to Stuff Envelops § To demonstrate some of these principles lets do a simple hands on activity § TriFold, Stuff, Stamp and Seal 10 Letters § Time yourself (Pretend to Stamp and Seal) § First Round – Batch § Do all 20 of one step before moving to the next § Second round – Serial § Do each step for each letter before moving to the next § What did you notice
9. 9 LEAN METHODOLOGY
10. 10 LEAN - DEFINE VALUE § VALUE (FROM THE CUSTOMER'S PERSPECTIVE) § WHAT DO CUSTOMERS WANT? § Is it: Speed, Features, Service?
11. 11 VALUE STREAM § MAP THE STEPS IN THE STREAM § IDENTIFY § Points of Value § Points of Waste
12. 12 7 WASTES OF SOFTWARE DEVELOPMENT § MANUFACTURING § Inventory § Overproduction § Extra Processing § Transportation § Waiting § Motion § Defects § DEVELOPMENT § Partially Done Work § Extra Features § Relearning § Handoffs § Delays § Task Switching § Defects

14. 14 CREATE FLOW § ECONOMIC VIEW - FOCUS ON VALUE AT EVERY LEVEL § ACTIVELY MANAGE QUEUES - SHORTER QUEUES § UNDERSTAND AND EXPLOIT VARIABILITY - MITIGATE VARIABLES § REDUCE BATCH SIZES - SMALLER UNITS § APPLY WORK IN PROGRESSCONSTRAINTS (WIP) - SERIALIZE § CONTROL FLOW UNDER CERTAINTY - CADENCE AND SYNCHRONIZATION § GET FEEDBACKAS FAST AS POSSIBLE - SHORTER FEEDBACK CYCLES § DECENTRALIZE CONTROL - REDUCE DELAYS IN DECISION MAKING
15. 15 MODIFIED VALUE STREAM 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 1 2 3 4 5 6 7 Original Modified -Value Delivered Sooner - Mitigate Variable of Change - Reduced Batch Sizes - Reduced WIP (from 3 to 1) - Faster Feedback
16. 16 PULL § The right amount pulled at the right time, no more, no less) § Limit Over Production & Waste - Respond Quicker to change § Don’t do anything until its needed then do it fast http://www.handsongroup.com/lean-manufacturing-topic-of-the-day-from-make-to-stock-to-make-to-order/
17. 17 PERFECTION § Perfection (elimination of all waste in the value stream) § Implement Kaizen and Continuous Improvement Processes § Celebrate Successes
18. 18 REAL LIFE EXAMPLES
19. 19 COFFEE MAKERS Batch Single vs
20. 20 CUPCAKES Batch Flow vs
21. 21 AUTOMOBILE PAINTING Batch vs Eliminating Delays
22. 22 BURRITOS Batch and Continuous flow
23. 23 APPLYING IN LEAN IN PRACTICE
24. 24 DISCUSS • WHAT IS VALUE • WHAT IS THE VALUE STREAM • Where is our waste • HOW DO WE CREATE FLOW • HOW DOES PULL APPLY • HOW CAN WE IMPLEMENT KAIZEN
25. 25 DISCUSS • WHAT IS VALUE • WHAT IS THE VALUE STREAM • Where is our waste • HOW DO WE CREATE FLOW • HOW DOES PULL APPLY • HOW CAN WE IMPLEMENT KAIZEN
26. 26 7 WASTES OF SOFTWARE DEVELOPMENT § MANUFACTURING § Inventory § Overproduction § Extra Processing § Transportation § Waiting § Motion § Defects § DEVELOPMENT § Partially Done Work § Extra Features § Relearning § Handoffs § Delays § Task Switching § Defects
27. 27 DISCUSS • WHAT IS VALUE • WHAT IS THE VALUE STREAM • Where is our waste • HOW DO WE CREATE FLOW • HOW DOES PULL APPLY • HOW CAN WE IMPLEMENT KAIZEN
28. 28 CREATING FLOW § ECONOMIC VIEW - FOCUS ON VALUE AT EVERY LEVEL § ACTIVELY MANAGE QUEUES - SHORTER QUEUES § UNDERSTAND AND EXPLOIT VARIABILITY - MITIGATE VARIABLES § REDUCE BATCH SIZES - SMALLER UNITS § APPLY WORK IN PROGRESS CONSTRAINTS (LIMIT WIP) - SERIALIZE § CONTROL FLOW UNDER CERTAINTY - CADENCE AND SYNCHRONIZATION § GET FEEDBACK AS FAST AS POSSIBLE - SHORTER FEEDBACK CYCLES § DECENTRALIZE CONTROL - REDUCE DELAYS IN DECISION MAKING
29. 29 DISCUSS • WHAT IS VALUE • WHAT IS THE VALUE STREAM • Where is our waste • HOW DO WE CREATE FLOW • HOW DOES PULL APPLY • HOW CAN WE IMPLEMENT KAIZEN
30. 30 CREATING FLOW § The right amount pulled at the right time, no more, no less) § Limit Over Production & Waste § Respond Quicker to change § Don’t do anything until its needed then do it fast
