01 · Record the first operation
What the team finds
A batch is marked complete at one stage, but work-in-process remains beside the station. Connect batch milestones, product mix and the observed transfer interval.
02 · Decide at a later review
Who acts, and what changes
Responsible team · Production planning lead
At the root-cause review, approve a pickup sequence and transfer responsibility instead of adding more buffer space. Assign the material-flow lead for the next run.
03 · Verify in the next comparable operation
How the team checks the result
With similar batches, verify the pickup sequence. Compare WIP dwell, repeat moves and time to the next productive stage.
