  11. 12. So let’s go find a problem! Sherlock Holmes (Sidney Paget, 1904)
  12. 13. Total Cost of Quality Performance (For Calendar Years) % of Sales Quality Performance Good, But improvement slowed Standard for external cost of quality ISO TWI Lean
  13. 14. I think we found a problem!
  14. 15. External Cost of Quality <ul><li>Reality check: “Good is the enemy of Great” </li></ul><ul><ul><li>Large OEMs demand low (zero) PPM defect rates </li></ul></ul><ul><ul><li>“ One size fits all” supplier measurement: Defective PPM </li></ul></ul><ul><ul><li>Ever-increasing quality expectations: </li></ul></ul><ul><ul><ul><li>What was a good part in the past is often rejectable today </li></ul></ul></ul><ul><li>Characteristics of Donnelly’s External Cost of Quality </li></ul><ul><ul><li>70% of External Cost of Quality is in each quarter’s top ten rejects </li></ul></ul><ul><ul><li>Few are repeat rejects: Over 85% are first-time issues </li></ul></ul><ul><ul><li>No trends in terms of shift, production area, customer, material, machine, method </li></ul></ul><ul><ul><li>Key categories: part/mold/material design issues, increasing customer expectations, and simple human mistakes </li></ul></ul>
  15. 16. Quality Performance (one part #) Mistake One mistake on one box = March PPM of 1,341vs. Customer expectation = 500 Good parts Rejects
  16. 17. Types of Mistakes <ul><li>Family mold box labeling in production </li></ul><ul><li>Switched labels in shipping – similar part numbers </li></ul><ul><li>Forgot to clip post that looked like a normal part feature </li></ul><ul><li>Core change done wrong </li></ul><ul><li>Piece broke off in mold </li></ul><ul><li>Measured wrong dimension for SPC </li></ul><ul><li>Coolant inadvertantly turned off </li></ul><ul><li>Missing inserts / assembly parts </li></ul><ul><li>Inserts /assembly parts oriented incorrectly </li></ul>
  17. 18. Human performance issues Why existing tools are not enough <ul><li>Motorola findings: </li></ul><ul><li>...it became evident early in the project that achieving a C p greater than 2 would go only part of the way. Mistake-proofing the design would also be required ... Mistake-proofing the design is an essential factor in achieving the [total number of defects per unit] goal. </li></ul><ul><li>Smith, B. IEEE Spectrum 30(9) 43-47 </li></ul>High process capability: necessary but not sufficient
  18. 19. Achieving Great Quality Performance <ul><li>Ensure dimensional capability – PPAP </li></ul><ul><li>Identify and reduce risk of part failure – FMEA </li></ul><ul><li>Mistake-proof the design: still isn’t enough </li></ul><ul><li>Error-proofing your processes is also required </li></ul><ul><li>This requires everyone’s involvement: legacy parts </li></ul>But how?

  22. 23. Mistake-proofing: Not a Substitute <ul><li>Don’t substitute mistake-proofing for: </li></ul><ul><li>Personal accountability (and related supervisory actions) (JR) </li></ul><ul><li>Effective training (JI) </li></ul><ul><li>Good organization and cleanliness (5S) </li></ul><ul><li>Standard work and simplified processes (JM) </li></ul><ul><li>Strong quality system </li></ul>

  25. 26. Results <ul><li>Mindset changes occurring </li></ul><ul><ul><li>“ Just try harder” giving way to more permanent fixes </li></ul></ul><ul><ul><li>Less finger pointing, more working together and celebrating successes </li></ul></ul><ul><li>Substantially reduced rejects due to mistakes </li></ul><ul><li>Cut PPM defect rate by more than half ... so far </li></ul><ul><li>With one major OEM customer, went from being “on probation” to being a top supplier </li></ul><ul><li>Also achieved significant benefits in reducing equipment damage and safety incidents </li></ul>
  26. 27. Total Cost of Quality Performance (For Calendar Years) % of Sales Quality Performance Good, and improving again Standard * YTD through March ISO TWI Lean
