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. The result to review Batch-linked transfer delay and WIP dwell [Explore this application](https://www.fortuneai.app/industries/production-operations/applications/root-cause-analysis/)[See how the product works](https://www.fortuneai.app/industries/production-operations/workflow/) More operating situations ## Different situations.
