  1. Decision Making • Decision Framework • Context • Criticality • Concurrent Environment • Variation • Decision Matrix • General discussion • Pugh Matrix • Scoring • FMEA • Four Blocker • Best Practices and Pitfalls

  2. Matrix example

  3. Decision Matrix Tools • Types of Matrix Tools • QFD- Formative tool, positive • Decision Matrix- selection • FMEA- Assessment, negative • Four Blocker- Quick selection • Tool Fundamentals • Relate solutions to criteria • Scoring • Weighting • Best Practices and Pitfalls

  4. QFD a structured way to identify best means to meet customer CTQ’s or requirements QFD Simplified Form QFD Example

  5. Helps Make Selection

  6. Pugh Matrix Example- Selection and Concept Improvement

  7. Examples from Last Year

  8. This FMEA Form is Relatively Complete. You Will be Using a Simplified Form This Form Includes Most of the Features of a FMEA, You will be using a simplified FMEA

  9. FMEA Example

  10. Four Blocker Screening- easy and quick initial screening tool Example- Help a one arm man lift a heavy box 10 Special lift strap Good Bet Possible Chance of Working 5 Bionic Arm Possible Unlikely 1 Easy Hard Ease of Implementation

  11. Pitfalls: • Long “laundry” list of criteria • Two or more candidates with nearly identical scores • Putting too much trust in the tool • Self serving, ie, make the matrix support your bias • The Tool becomes the end not the means Best Practices: • Use only critical/ important criteria(some criteria like safety can be Go/No Go) • 9,3,1 or Pugh +- scoring; make sure you differentiate • Reevaluate scores, weightings and potential design improvements • Keep it simple; do what is needed for the decision but no more Make the Tools Work for You
