Spring Production Yield Without Hiding Rejected Parts

Quick answer: Define the input population, accepted quantity, rework and rejects for a stated batch and inspection stage.

How should yield be reported transparently?

Combining first-pass and post-rework results can hide a process problem. Use consistent definitions when comparing periods. The rejected population also supplies evidence for design or process improvement, so keep failure categories rather than only a total percentage.

A practical verification method

Reconcile the reported quantities with batch records and confirm the same stage and definitions were used.

ItemWhat to recordPurpose
Reference configurationPart or assembly identity and drawing revisionMake comparisons traceable
Test conditionsRelevant position, direction and operating conditionCompare the same characteristic

Use the result in an engineering request

Describe the observed condition and the required function separately. Include the relevant drawing revision and your results from the check above. If an acceptance limit has not been established, identify it as an open design input rather than treating a successful trial as approval.
