Why The Same Issues Keep Coming Back?

You flagged a defect. The supplier promised it was fixed. The next batch has the same problem.

This is not bad luck. It is what happens when suppliers fix the symptom without changing the process. The defect gets patched. No documentation. No root cause analysis. No one checks whether the fix actually held.

Why it keeps happening

Verbal fixes are forgotten. New production staff aren't trained on what changed. The factory's internal QC doesn't flag the same issue because no one updated the checklist. And the buyer, receiving a report days after the inspection, has no visibility into whether corrections were actually implemented.

The cycle repeats because the system that produced the defect is still running unchanged.

How to break it

Demand documentation, not assurances. When a defect is flagged, require a corrective action plan — root cause, fix, owner, timeline, and proof. Photos, updated checklists, revised SOPs. "It's fixed" is not an answer.

Book an inline inspection on the next order. Inline inspections are the only reliable way to confirm that corrections are being followed during production, before it's too late to change anything. LTV runs all inspections on KaizenQ — defects are logged in real time on the factory floor, with photos and timestamps. If the same issue reappears, it's visible immediately — not in a report that arrives two days later.

Review the process, not just the product. Updated instructions, proper training, calibrated tools, stable workflows — these are what prevent repeat failures. A factory that can't show you these has not fixed the problem.

Follow up on the next batch regardless. Make it a standing rule.
