Where it usually breaks
And how to keep it from happening.
- A changed promise hides the delay. Preserve the accepted delivery time when the actual pickup is later than expected. Transport Supervisor needs the original commitment to investigate the result.
- A free driver has a busy vehicle. Check both commitments. Different driver names do not resolve a shared vehicle overlap.
- A response is unclear. Look up the existing receipt and its operation identity before deciding what action remains necessary.
