Editorial draft available to read. Factual and language review is pending. Examples are illustrative.
Decision and scope
First define what counts as completed production and which plan version is being compared. Separate manufactured, accepted and dispatched units. Fix the period, production line and treatment of rework. Changing the denominator during a shift can improve the reported percentage without improving the underlying production outcome.
Illustrative example
Illustrative example: the frozen plan requires one hundred accepted pieces. Ninety are manufactured, with five still awaiting inspection. If the metric measures accepted output, its numerator is eighty-five rather than ninety. Show the five pending pieces separately and retain the plan revision beside the reported result.
Acceptance check
Test a zero plan, cancellations and late-arriving records. Avoid division by zero and percentages without an explicit basis. Accept the metric when supervisors can reproduce both numerator and denominator from individual records, identify pending output and explain changes between two views of the same reporting period.
Key takeaways
- Accept the metric when supervisors can reproduce both numerator and denominator from individual records, identify pending output and explain changes between two views of the same reporting period.
