PerformanceKeep the cohort and the denominator stable
OTIF, fill rate, perfect order, inventory accuracy, and quality percentages measure different things. Define the orders, units, records, or positions assessed, and apply the same inclusion rules to each period. A combined success rate requires an observed intersection; multiplying separate percentages does not reconstruct it. Record exclusions so an improved result is not merely a changed denominator.
Explain movement before setting a target
A utilization increase may signal improved use of resources or growing congestion. High inventory turnover can coexist with stockouts. Separate a measurement from an explanation, and compare rates with workload, timing, service, and data quality. These tools calculate entered observations; they do not select a universal benchmark. Follow a surprising change back to the source transactions before rewarding, penalizing, or redesigning a process.
