Presentation Transcript

  1. Problem Solving Kimball Bullington, Ph.D., P.E. Associate Professor Middle Tennessee State University

  2. Where are we going? • What is a problem anyway? • Problem Solving Methodologies • Using DMAIC as a Model • One Powerful Technique

  3. Problem What is a problem, anyway?

  4. What is a problem anyway? • prob·lem/ˈpräbləm/Noun: 1.A matter or situation regarded as unwelcome or harmful and needing to be dealt with and overcome. • 2.A thing difficult to achieve or accomplish.

  5. What is a problem anyway? • Can we separate problems from causes and solutions? It isn’t easy.

  6. Some Problems are Difficult • Lack of clarity • Multiple goals • Complexity • Dynamics

  7. Some Problems are Difficult • Lack of clarity • Multiple goals • Complexity • Dynamics

  8. Where are we going? • What is a problem anyway? • Problem Solving Methodologies • Using DMAIC as a Model • One Powerful Technique

  9. Problem Solving Methodologies • Kepner / Tregoe • GROW • How to Solve It • Productive Thinking • TIPS (TRIZ) • PDCA / DMAIC Wikipedia, 12/13/11

  10. Kepner / Tregoe • The Rational Manager • Problem analysis • Decision making • Potential problem analysis • Direction and Control

  11. GROW • Goals • Reality • Obstacles / Options • Way forward Example: weight loss Wikipedia, 12/13/11

  12. Problem Solving Methodologies • Kepner / Tregoe • GROW • How to Solve It • Productive Thinking • TIPS (TRIZ) • PDCA / DMAIC

  13. How to Solve it: 4 Principles • Understand the problem • Devise a plan • Carry out the plan • Review / extend How to Solve It: George Polya Wikipedia, 12/13/11

  14. Productive Thinking: 6 Steps • What’s going on? • What’s success? • What’s the question? • Generate answers • Forge the solution • Align resources Wikipedia, 12/13/11

  15. TIPS / TRIZ • Theory of Inventive Problem Solving • Specific Problem • Typical Problem (contradiction) • Typical Solution • Specific Solution • Inventive principles and standards

  16. Where are we going? • What is a problem anyway? • Problem Solving Methodologies • Using DMAIC as a Model • One Powerful Technique

  17. PDCA / DMAIC

  18. DMAIC • Define • Measure • Analyze • Improve • Control

  19. Lean or Six Sigma? • Lean • Flow • Waste • Six Sigma • Variability • Defect • Implementation

  20. Why Four Sigma? • Most businesses are in the three to four sigma range • Can’t jump to six sigma • 80 / 20 rule • Simple first, complex later

  21. Where are we going? • What is a problem anyway? • Problem Solving Methodologies • Using DMAIC as a Model • One Powerful Technique

  22. SWOT Analysis

  23. SWOT Analysis

  24. SWOT Analysis

  25. SWOT Analysis

  26. Take-aways • What is a problem anyway? • Problem Solving Methodologies • Using DMAIC as a Model • Using CED’s to better define your problem causes
