- 15. External Cost of Quality Reality check: Good is the enemy of Great Large OEMs demand low (zero) PPM defect rates One size fits all supplier measurement: Defective PPM Ever-increasing quality expectations: What was a good part in the past is often rejectable today Characteristics of Donnellys External Cost of Quality 70% of External Cost of Quality is in each quarters top ten rejects Few are repeat rejects: Over 85% are first-time issues No trends in terms of shift, production area, customer, material, machine, method Key categories: part/mold/material design issues, increasing customer expectations, and simple human mistakes

Mistake-proofing & Core Values Do your best Eliminate barriers like mistakes so we can take pride in what we do Treat others the way you want to be treated With respect for the human condition Dont be afraid to ask for help Identify mistakes and work with others to discover the root cause Always work as a team Mistake-proofing builds teamwork
- 25. Structured Approach to Mistake-proofing What went wrong what mistake was made? Is it an honest mistake (Job Relations)? Identify the root cause(s) Has the job been streamlined using Job Methods? Was Job Instruction used to train effectively? Use 3-legged 5-why Develop the best solution Consider cost versus risk Is the right way the easy way? Apply the solution Is the risk resolved?
- 26. Results Mindset changes occurring Just try harder giving way to more permanent fixes Less finger pointing, more working together and celebrating successes Substantially reduced rejects due to mistakes Cut PPM defect rate by more than half ... so far With one major OEM customer, went from being on probation to being a top supplier Also achieved significant benefits in reducing equipment damage and safety incidents
