How to Choose an ERP for Your Trading Company
AQL sampling is the foundation. Determine sample size based on batch quantity, then use the acceptable quality level to decide pass or fail. If defective units exceed the limit, the batch needs 100% inspection or rework.
Different products need different inspection focuses. Metals: dimensional tolerance and finish. Electronics: functional testing and ESD. Textiles: color and defects. Ceramics: deformation and glaze. A one-size-fits-all checklist is unprofessional.
Pre-Production Inspection is often overlooked but critical. Checking raw materials and first articles before mass production prevents disasters. One PPI costs far less than reworking an entire production run.
Build a supplier quality scorecard. My dimensions: product pass rate 40%, on-time delivery 25%, cooperation 15%, price 10%, response speed 10%. Any supplier below 80 for three months needs reassessment.
