Stop the recurring leak

1. Contain affected lotsMaya · Quality
   Day 1–3 · Every held lot has a traceable release decision.

2. Test the causeLeon · Engineering
   Day 4–10 · Show why the leak happens and why checks missed it, using repeatable tests.

3. Pilot the correctionAva · Production
   Day 11–17 · No more than four first-test failures in 300 pilot units, no new failure mode.

4. Verify and standardizeNoah · Quality
   Day 18–30 · Comparable validation meets the 1.5% goal; recurrence response has an owner.

Proposed timing and fictional owners. Close each action after its check is met; a date alone does not prove completion.

1. SortSeparate suspect assembliesMaya · Quality

   Identify the affected lot boundary and quarantine suspect seals, fixtures and assemblies through the existing containment owner.

   Day 1–3 · Every suspect lot has a traceable disposition; conforming and suspect parts cannot mix.

2. Set in orderGive fixtures a clear homeLeon · Engineering

   Separate approved fixtures from trial fixtures and arrange the validated setup tools at the test station.

   Day 4–10 · Two operators retrieve the correct fixture without relying on memory; trial items remain segregated.

3. ShineExpose recurring residueLeon · Engineering

   Clean accessible approved surfaces and record where residue returns; engineering investigates the source before closure.

   Day 4–10 · The residue source is investigated and the approved response is checked on the next comparable run.

4. StandardizeKeep one approved setupAva · Production

   Issue the accepted fixture/setup check only after the 8D correction passes its trial; remove obsolete copies.

   Day 18–21 · The released revision matches the trial evidence and operators demonstrate the check.

5. SustainCheck the next lotsNoah · Quality

   Review comparable final-test results and setup records through day 30, recording every failed check and response.

   Day 22–30 · The failure denominator, setup record and unresolved actions are visible; the goal is not reported as achieved without results.

6. SafetyReview the work controlsMaya · Quality

   The competent area lead reviews handling, isolation and test-station access before any fixture change and after the pilot.

   Day 1–30 · Required work approvals and unresolved concerns are recorded; the project board does not authorize machine changes.
