The initial trial run of the product, always performed in-house, is done to verify that the fixture is capable of meeting drawing specifications and minimizing the rejection rate. Statistical process control charts are kept for resin input and output quality. If the process is deemed out of control, a modification schedule for a new trial run is scheduled. An evaluation meeting is held to inform all departments about potential problems. Cause-and-effect judgments are made and reconciled via modification request sheets. Target finish dates also are established at this meeting.
