Chapter 9

1. Chapter 9 Problem-Solving Using Define, Measure, Analyze, Improve, Control

2. Problem-Solving • If you don’t know where you are going, you will probably end up somewhere else. • Laurence J. Peters • Author and business theorist

3. Problem-Solving • Dr. Deming’s Plan-Do-Study-Act Cycle

4. Problem-Solving • Six Sigma projects have five phases: • Define • Measure • Analyze • Improve • Control (note similarity to PDSA)

5. Problem-Solving • Define • Identify the problem/project • Define the requirements • Establish the goals to be achieved

6. Problem-Solving • Measure • Gather information about the current process • Define and measure key process steps and inputs • Refine the problem statement and goals

7. Problem-Solving • Analyze • Identify potential root causes of the problem • Validate the cause and effect relationship • Identify the vital few root causes

8. Problem-Solving • Improve • Implement solution to address root causes of problem • Test solutions • Measure results

9. Problem-Solving • Control • Evaluate and monitor improvements • Make adjustments as needed • Establish standard procedures

10. Problem-Solving • Eight essential tools typically used within DMAIC process • Process Maps • Cause and Effect Diagrams • Failure Modes and Effects Analysis • Measurement System Analysis • Process Capability Studies • Multi-variate studies • Design of Experiments • Process Control Plans

11. Problem-Solving • Seven Tools of Quality proposed by Kaoru Ishikawa • Flow Chart • Control Chart • Check Sheet • Histogram • Pareto Diagram • Cause and Effect Diagram • Scatter Diagram
