I'm sorry John I disagree with the "experiencing problems of this nature with a new design" As a new product, it should never leave the factory without ALL processes in place albeit material sourcing, manufacture, and logistics. Design, development, process capabilities, and a full quality procedure has to be in place before the product can proceed to manufacture. In a creditable company the finalised project has to signed off by the Technical & Managing Director before the first product can be shipped As a Chartered Engineer for over 30 years it galls me that the customer is now the a non paid member of the Project Test and Quality team.
