Approving a Process for Production

Summary: The introduction of a new process into the factory often precipitates a great deal of confusion and defective products. The primary cause is a lack of thorough investigation of the nature of the process, its precision capabilities, and the optimum operating conditions, and communication of this information to the operating personnel. This paper presents an eight-point program for the approval of complex new processes prior to their introduction to production. Data collection is based on response surface experiments, in conjunction with optimization procedures and the use of Shewhart concepts in the measurement of process capability and measurement repeatability. Use of the procedures has resulted in greater confidence in new processes and in demonstrably better processes, both in the development laboratory and in the factory.
