6 Key Concepts of Quality Process focus. Customer focus. Collaboration. Data driven management. Strategic planning for quality. 6

8 WHAT is Lean? Systematic approach. Set of principles and practices. Way of thinking. 8

9 Lean Focuses on: Eliminating waste and non-value-added activities. Maximizing the value delivered to customers. Optimizing flow of products and services. 9

10 WHAT is value? Customer wants you to do it. The material or information is being transformed to final product or service. It is done right the first time. 10

11 WHAT is waste? Waste 1. Overproduction 2. Inventory 3. Transportation 4. Waiting 5. Motion 6. Over Processing 7. Correction or Rework 11

12 WHAT is Lean? Definition: A systematic approach to identifying and eliminating waste through continuous improvement by flowing the product or service at the pull of the customer in pursuit of perfection. Defined by National Institute of Standards and Technology (NIST) 12

13 13

14 WHAT is Six Sigma? Philosophy Set of tools Methodology Metrics 14

15 Six Sigma Focuses on: Putting customers first. Reducing process variation. Enhancing process control. 15

16 WHAT is Six Sigma? Definition: A fact-based, data-driven philosophy of improvement that values defect prevention over defect detection. It drives customer satisfaction and bottomline results by reducing variation and waste, thereby promoting a competitive advantage. It applies anywhere variation and waste exist, and every employee should be involved. Defined by American Society of Quality (ASQ) 16

18 WHAT is Lean Six Sigma? Method Engine Mindset Toolkit 18

19 Lean Six Sigma Focuses on: Delighting customers with speed and quality. Improving processes. Working together for the greater good. Basing decisions on data and facts. 19

20 WHAT is Lean Six Sigma? Definition: A fact-based, data-driven philosophy of improvement that values defect prevention over defect detection. It drives customer satisfaction and bottom-line results by reducing variation, waste, and cycle time, while promoting the use of work standardization and flow. It applies anywhere variation and waste exist, and every employee should be involved. Defined by American Society of Quality (ASQ) CONTROL IMPROVE DEFINE lean ANALYZE MEASURE 20

22 WHY would you use Lean Six Sigma? Manage quality into the business process. Meet or exceed customer needs or requirements. Improve performance and effectiveness. Transform your organizational culture. 22

23 WHEN would you use Lean Six Sigma? Customers still complain about your products or services. Employees complain about the roadblocks to serving customers. Everyone blames the customers and/or employees. 23

24 Improvement Methods 24

25 PDSA Cycle Also called Plan-Do- Check-Act (PDCA) cycle Four-step model for carrying out change ACT PLAN DO STUDY 25

26 PDSA Cycle Recognize an opportunity and plan a change. PLAN ACT DO STUDY 26

27 PDSA Cycle Test the change. Carry out a smallscale study. PLAN ACT DO STUDY 27

28 PDSA Cycle Review the test. Analyze the results. Identify what you learned ACT PLAN DO STUDY 28

29 PDSA Cycle Take action based on what you learned. Use what you learned to plan new improvements. Begin cycle again. ACT PLAN DO STUDY 29

30 DMAIC Method Pronounced Duh-MAYick Structured problemsolving methodology Uses project management and statistical tools for each phase DEFINE MEASURE ANALYZE IMPROVE CONTROL Define the problem + what is required to satisfy customers Map the current process to collect data Investigate and identify what causes the problem Implement a fix that will solve the problem Sustain the improved results 30

31 DMAIC Method DEFINE Define the problem + what is required to satisfy customers MEASURE ANALYZE IMPROVE Map the current process to collect data Investigate and identify what causes the problem Implement a fix that will solve the problem CONTROL Sustain the improved results 31

32 DMAIC Method DEFINE Define the problem + what is required to satisfy customers MEASURE ANALYZE IMPROVE Map the current process to collect data Investigate and identify what causes the problem Implement a fix that will solve the problem CONTROL Sustain the improved results 32

33 DMAIC Method DEFINE Define the problem + what is required to satisfy customers MEASURE ANALYZE IMPROVE Map the current process to collect data Investigate and identify what causes the problem Implement a fix that will solve the problem CONTROL Sustain the improved results 33

34 DMAIC Method DEFINE Define the problem + what is required to satisfy customers MEASURE ANALYZE IMPROVE Map the current process to collect data Investigate and identify what causes the problem Implement a fix that will solve the problem CONTROL Sustain the improved results 34

35 DMAIC Method DEFINE Define the problem + what is required to satisfy customers MEASURE ANALYZE IMPROVE Map the current process to collect data Investigate and identify what causes the problem Implement a fix that will solve the problem CONTROL Sustain the improved results 35

37 STEPS to DMAIC Method PHASE 1: DEFINE Team and sponsors reach agreement: what the project is what it should accomplish Project team focus: Complete analysis of what the project should accomplish Confirm understanding with sponsor(s) 37

38 STEPS to DMAIC Method PHASE 2: MEASURE Project team focus: What is causing the problem to happen Collect data to answer question(s) Narrow down the problem Whatcom County Health Department % WIC Nutrition Program No Show per Appointment Type/ Whatcom CHD 54% Pareto Chart 74% 88% Second Contact Check Pickup Recertification Health Assessment 100% Registered Dietitian 120% 100% 80% 60% 40% 20% 0% Marc Findings: Analysis of all appointment types for the year 2012 show that the top five are Second Contact, Check Pick-up, Recertification, Health Assessment, and Registered Dietitian. Of these five appointment types: Second Contact, Check Pickup, and Recertification comprise 74% of the no shows. 38

39 STEPS to DMAIC Method PHASE 3: ANALYZE Project team focus: Identify the root causes for problem(s) Agency Customer Experience Employee 39

40 STEPS to DMAIC Method PHASE 4: IMPROVE Project team focus: Verify root causes Identify solutions & practical method Test and evaluate effectiveness and feasibility of proposed solution Implement permanently 40

41 STEPS to DMAIC Method PHASE 5: CONTROL Project team focus: Verify how much improvement was made, if any at all Confirm root causes have been reduced Implement fully Review indicators/measures from DEFINE phase Incorporate solutions into daily work Monitor process 41

42 How do they compare? 42

48 PRINCIPLES to Lean Six Sigma Focus on the customer. Identify and understand how work gets done. Manage, improve and smooth the process flow. Remove non-value-adding steps and waste. Manage by fact and reduce variation. Involve and equip the people in the process. Undertake improvement activity in a systematic way. 48
