Adjusted variance = physical quantity − book quantity − approved adjustments. Shrinkage = loss units ÷ book quantity.
How to use the result
Use the same scope, period and units when comparing shifts or sites. Investigate the process behind the number before setting a target. A higher rate is useful only when accuracy, safety and service remain controlled.
Data checks before calculation
- Keep direct task hours separate from breaks, meetings and unrelated work.
- Use one unit of measure throughout the calculation.
- Record exclusions and approved adjustments instead of silently changing source data.
- Compare against your verified historical baseline, workload mix and operating constraints.
