Describes the general requirements for the implementation of Statistical Process Control (SPC). It is intended for use by individuals in electronics and other industries that are involved in the planning, implementation and evaluation of an SPC system. Thus, it outlines SPC philosophy, implementation strategies, tools and techniques that may be implied in different sequences on the specific company, operation or variables under consideration in order to relate process control and capability to end-product requirements.
