Count each minute once before looking for a bottleneck.

In this kit's fictional time study, batch TS-801 has 30 active minutes, including 4 minutes correcting labels, plus 20 minutes waiting for approval. Ten orders are completed.

That gives 50 elapsed minutes, 5.0 minutes per completed order and a 40% waiting share. The 4 rework minutes are already inside active time. Adding them again would overstate the observation.

Try this on one repeatable process:

• Define the start, finish and what counts as a completed unit before timing • Record active and waiting minutes separately, with rework kept inside active time • Follow the waiting evidence to its dependency. Here, the batch is waiting for label approval • Test a small change, such as a scheduled label-file pre-check, while keeping required approvals and tracking label corrections • Observe comparable batches again. Keep the original records and note changes in order mix before attributing a faster result to the trial

The preview is the actual Calculate and compare page from the kit's fictional completed example. The Process Time Study and Bottleneck Review Kit includes an editable Word packet, Excel tracker, matching print PDF, fictional completed example and Quick Start.

A short observation supports a process investigation. It does not establish a staffing level or an employee performance rating.
