Cold Calling vs Cold Emailing for B2B

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.

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.

An inspection report should be professional and thorough: date, product info, batch size, sample size, defect descriptions, defect rate, pass/fail determination, and improvement suggestions. Photos make it more convincing.
