The MRB and Nonconformance Kit HandbookChapter 15 of 26

Cost and trends

Two numbers per NCR, where it was found and what it cost, turn the log into the strongest argument a quality manager has for earlier detection. The log's breakdown (D19) totals both; the trend spreadsheet (F09) adds the monthly trend with control limits and Paretos by defect, cause and operation.

MeasureWhy it mattersWatch out for
Open NCRs by ageProduct on hold is cash and lead timeLines closed before the product action is done
Days from found to dispositionHow fast the system decidesDispositions recorded before the approvals are in
Customer authorizations waiting, and their ageProduct stuck on someone else's deskRequests never sent
Share found at final inspection or by the customerHow well in-process checks workIn-process finds not written up
Cost of nonconformance by where foundThe price of late detectionCost left blank because it is not exact
Repeats by defect, part, operation, supplierWhether corrective actions holdRepeats hidden by new part numbers
Hold-area reconciliation mismatchesWhether the cage and the records agreeWalks skipped in busy weeks
