Inspection is a necessary but non-value-adding activity whose purpose is to protect the customer from poor quality. We should therefore do as little as possible, upon condition that our inspection plan meet the customer’s requirement. Inspection plans with acceptance numbers of zero (c=0) minimize the sample size, albeit at the cost of a higher producer’s risk of rejecting lots at the specified acceptable quality level (AQL). This presentation will show how to define c=0 plans whose customer protection is equivalent to that of the corresponding ANSI/ASQ Z1.4 (formerly MIL-STD 105) plan.
Areas Covered in the Session :
Attendees will also receive an Excel spreadsheet that shows the operating characteristic (OC) curve for a c=0 plan and compares it to the original ANSI/ASQ Z1.4 plan. Attendees can replace the example’s specification with their own.
Who Should Attend:
William (Bill) A. Levinson, P.E., is the principal of Levinson Productivity Systems, P.C. He is an ASQ Fellow, Certified Quality Engineer, Quality Auditor, Quality Manager, Reliability Engineer, and Six Sigma Black Belt. He holds degrees in chemistry and chemical engineering from Pennsylvania State and Cornell Universities, and night school degrees in business administration and applied statistics from Union College, and he has given presentations at the ASQ World Conference, TOC World 2004, and other national conferences on productivity and quality.
Mr. Levinson is also the author of several books on quality, productivity, and management. Henry Ford’s Lean Vision is a comprehensive overview of the lean manufacturing and organizational management methods that Ford employed to achieve unprecedented bottom line results, and Beyond the Theory of Constraints describes how Ford’s elimination of variation from material transfer and processing times allowed him to come close to running a balanced factory at full capacity. Statistical Process Control for Real-World Applications shows what to do when the process doesn’t conform to the traditional bell curve assumption.
