Compare performance against the work actually assigned — not only a raw rate that ignores travel, route and workload differences.
If Picker A walks materially further than Picker B, a simple picks-per-hour table can turn an allocation difference into an apparent performance problem. Waremetry can model the additional route burden and calculate a route-adjusted expectation.

Waremetry reporting is designed to support fair, evidence-based performance management aligned with ACAS principles. The analytics can identify patterns and provide context, but the employer still needs a fair process, employee input, appropriate support and its own HR procedures.
Raw view: Picker A = 82 units/hour against a standard target of 100.
Context: the assigned route carried materially higher walking distance.
Adjusted view: route-adjusted expectation = 80.6, meaning actual performance was above the contextual expectation.
Illustrative example only. A real model is calibrated to the client's layout, process and available WMS data.
