What To Do When Production Has Already Started But Problems Keep Appearing
from China Manufacturing Decoded · host Sofeast
What should you do when production is already underway, but quality problems keep appearing from one shipment to the next? In episode 336, Adrian and Renaud answer a listener question from David B. and explain how buyers should investigate recurring production problems before deciding whether to fix the situation or transfer manufacturing elsewhere. They begin by separating product design problems from manufacturing and workmanship issues. A product that cannot withstand normal use may be fundamentally under-designed, while products arriving dead on arrival are more likely to indicate manufacturing failures. The discussion also covers reliability testing, pilot production, supplier audits, corrective action plans, containment measures, documented process changes, fixtures and mistake-proofing. Renaud explains why inspections can provide useful short-term protection but should not become a permanent substitute for a functioning supplier quality system. If repeated mistakes continue, records are unavailable, or production is being moved between facilities without your knowledge, it may be time to walk away. You will learn: • How to distinguish design failures from manufacturing problems • When early production issues may be understandable • The warning signs that a supplier has no effective systems • What evidence to request after a supplier claims a problem is fixed • Why corrective action and inspection must be used together • When transferring production becomes the safest option Show Sections 00:00:13 – Introduction 00:00:59 – What to do when production problems keep appearing 00:02:14 – Design failures versus manufacturing problems 00:04:40 – Validating a new product before scaling up 00:07:00 – Problems during new product introduction 00:08:29 – When repeated mistakes mean it is time to walk away 00:10:15 – Using supplier audits to reduce risk 00:12:38 – Proving that a production problem has been fixed 00:15:38 – Fixtures, mistake-proofing and process improvement 00:19:09 – Corrective action versus more inspections 00:21:37 – When inspections become supplier babysitting 00:23:12 – Common weaknesses to investigate in the factory 00:24:58 – Conclusion Related content When and Why a Product Failure Analysis is Required QC During NPI: Build Quality In Before Mass Production Corrective Actions and Preventive Actions (CAPA) Guide Production Transfer: A Roadmap (Assembly Operations Only) Use a Corrective Action Plan After a Failed Inspection Supplier Quality Management: KPIs and Improvement Tools Get in touch with us Connect with us on LinkedIn Contact us via Sofeast's contact page Subscribe to our YouTube channel Prefer Facebook?
