Write a measurement definition
Specify the outcome, units, data source, and calculation. For picking time, for example, define when timing starts and ends and how exceptions are treated. Assign an owner and use the same definition before and after the trial.
Record the calculation beside the metric definition. For a duration where lower is better, one simple comparison is:
Keep the machine-readable definition with the result:
{
"metric": "picking_duration",
"unit": "seconds",
"start": "task accepted",
"end": "items delivered"
}Create a fair comparison
Collect a representative baseline and record demand, staffing, and operating conditions. Use a comparison site or period when feasible. Report the sample size and uncertainty instead of attributing every change to the intervention.
Report results with their limits
Separate simulated estimates from observed outcomes. Include the measurement period, implementation cost, and any changes that could affect interpretation. Record a decision to expand, revise, or stop the pilot based on the agreed success criteria.
