Why Finished Paint Waits: Find Delays between Polishing and Final Inspection

Track waiting between polishing and final inspection so workshop capacity improvements target delays as well as machine time.

A vehicle can finish machine polishing and still wait a long time for cleanup, inspection or release. If only polishing time is measured, the workshop may optimise the wrong part of the job.

Record milestone times

Use clear events such as polishing complete, ready for inspection, inspection started and accepted release. Record why a job is not ready rather than allowing every delay to appear as inspector waiting time.

Interval Possible cause
Polishing to inspection-ready Cleanup, residue removal or missing work
Ready to inspection Inspector availability or scheduling
Inspection to release Rework, documentation or customer timing

A practical example

If a vehicle spends 25 minutes in final cleanup and 70 minutes waiting for an inspector, reducing the compound’s cutting time by five minutes will not resolve the main delay. The appropriate action may involve inspection scheduling or clearer readiness signals.

Separate required waiting from avoidable waiting

Some product-specific processing intervals are necessary. Record them separately from queues caused by missing equipment or staff. Do not shorten required conditions to make the workflow chart look faster.

Trial one operational change

For example, schedule a defined inspection slot or add a visible ready-for-inspection state. Compare accepted turnaround and rework before extending the change.

The useful measure is how reliably a job reaches accepted completion. A workshop can improve delivery capacity without making operators polish faster when the largest losses occur after the machine has already stopped.
