When effectively and consistently applied, Configuration Management (CM) provides a positive impact on product quality, cost, and schedule. This standard is intended to assist in establishing, performing, or evaluating CM systems. CM is an integrated system of processes that ensure consistency of a product's performance, functional and physical attributes with its requirements, design, and operational information. The essence of CM, as portrayed in this consensus standard, is the common application of CM functions and their underlying fundamental principles, which have universal applicability across the broad spectrum of commercial and government enterprises. The standard provides an understanding of what to do, why a customer/suppler should do it, and when it is necessary to tailor the application of CM functions. This standard fulfills the important function of providing a rational basis upon which to apply good judgment in both planning for and executing CM across the enterprise.
