It is generally recognized that quality can not be inspected into the product, nor can it happen by accident. It should be built into the product by careful planning, analysis and control. This paper provides reinforcement for the proposition that quality is everyone's responsibility. But should other departments not be prepared to meet the challenge in all respects, quality control has an obligation to assure the manufacture of quality products. The paper presents several inspection plans to assure manufacturing quality and illustrates the dynamic programming approach to obtain an optimum balance between quality and cost.
