During the inspection, you found defects. The supplier acknowledged them, promised to fix the problem, and assured you that the next batch would meet all requirements. But when production continues or the next shipment arrives, the same issue shows up again.
Repeat defects are one of the most frustrating and costly issues in supply chain management. They damage trust, delay shipments, and create extra costs for sorting, rework, and re-inspections. And they raise one critical question: why are problems coming back even after being “fixed”?
The Problem: Surface Fixes Without Lasting Change
Most repeat issues come down to this: the supplier corrected the result, but not the process.
They may have reworked the defective batch or manually sorted items. But without improving the root cause, the same problem is likely to return. This is especially common when:
- The supplier did not perform a proper root cause analysis
- There was no corrective action plan, only a temporary fix
- Changes were made verbally, without documentation or control
- New staff were involved and not trained properly
- There was no follow-up after rework or re-inspection
Without clear process improvements and accountability, even trusted suppliers fall back into old patterns.
How to Prevent Repeat Issues from Happening Again
1. Don’t accept vague responses like “already fixed”
If the supplier simply says “It’s solved” without showing how or why, it’s a red flag. Ask detailed questions:
- What was the actual root cause?
- What changes were made to the process, equipment, or training?
- Who is now responsible for monitoring this?
2. Request a corrective action plan (CAP)
Make it standard practice to ask for a CAP when major or repeated issues occur.A real CAP should include:
- Root cause identification
- Corrective and preventive steps
- Timeline and responsible person
- Proof of implementation (photos, checklists, etc.)
3. Conduct in-process inspections during production
Don’t rely only on final inspections. For repeat issues, it’s critical to check during the early and middle stages of production. This helps ensure corrective actions are in place and working before everything is packed.
4. Review the process, not just the product
Many defects are a symptom of weak process control. Check if the supplier has:
- Updated and shared work instructions
- Calibrated tools and machines
- Consistent material handling or assembly steps
- Proper training for new workers
5. Follow up again – even after the issue is "closed"
Many suppliers apply quick fixes under pressure, but forget about them after one shipment. Re-check key points on the next order. Track repeat findings across shipments. Make clear that follow-up is part of your standard.
If your supplier promises something is fixed, but you keep seeing the same issue again, it means the process has not changed. Fixing the root cause, documenting improvements, and following up are the only ways to make sure the same problem doesn’t return.
