How to calculate labour minutes per container cycle

Short answer

Use completed cycles as denominator; time handling, processing, waiting and rework separately, then calculate labour minutes per cycle for comparable shifts.

Link tasks beyond loading to completed container cycles too.

Batch record

Work step
Labour minutes
Waiting minutes
Rework

Compare the same service

Code tasks from issue until the container is ready again. Divide shift labour minutes by completed cycles; separate waiting time from touch time.

Find the bottleneck

Compare total cycle time with direct work time; if waiting explains the gap, inspect the decision or area where work queues.
