25、 cost. This standard is intended to be used when establishing, performing, or evaluating CM processes. CM is a comprehensive process for maintaining consistency of any products performance, functional and physical attributes with its requirements, design, and operational information. The essence of
26、CM, as portrayed in this standard, is the common sense application of CM functions and their underlying fundamental truths (principles), which have universal applicability across the broad spectrum of commercial and governmental enterprises around the globe. An understanding of not just what to do,
27、but why, is necessary to tailor the application of CM functions. This standard fulfills an important function; it provides the rational basis upon which to apply good judgment in both planning for and executing CM. The standard treats CM principles like axioms in a geometry text; they are statements
28、 of fact to which implementing actions relate. The implementing actions for each CM function are defined in CM planning guided by the type of product involved and the environments in which it is to be developed, produced, marketed, distributed, used, and maintained. Because of the broad scope of its
29、 applicability, this standard is not written as a requirements document, per se, but as the foundation document upon which requirements may be structured. In the acquirer/supplier context there are several methodologies to conformance by a supplier: Acquirer requires a CM plan consistent with 649 fr
30、om the supplier. Acquirer uses 649 to develop a checklist with which to evaluate supplier CM plans. Acquirer reviews and approves the supplier CM plan and makes it a requirement on contract. This method requires both parties to the acquisition to understand both the concepts and the tailoring. Acqui
31、rer uses 649 as the basis for developing either or both an enterprise CM requirements document or a specific project CM requirements document to impose on suppliers. The requirements documents may state 649 principles as requirements and reference 649 paragraphs. Compliance with the contractual requ
32、irements constitutes conformance with 649. Since terminology varies considerably in different application environments, the standard provides equivalent terminology (aliases) for each defined term so that a user can substitute familiar language in a specific context. For example, while those of us p
33、roducing US military products use the term configuration item to describe components that we apply CM to, others use designated item or some other term. Regardless of the term used, the same principles apply. Section 5 of this standard is “normative;” the remainder of this standard is “informative.”
34、 1This revision replaces all previous revisions of this standard in whole. 1Normative elements contain provisions with which it is necessary to conform (as described in the text above) in order to be able to claim compliance with the standard, while informative elements provide useful supportive inf
35、ormation. iii EIA-649-B Revision Description of Change Release Date Interim Interim EIA standard EIA/IS-649 initiated to replace MIL-STD-973 by a task to develop an industry configuration management standard by ANSI project PN-3414. Aug 1995 _ ANSI/EIA-649 initiated by ANSI project PN-3721 to submit
36、 the industry configuration management standard for approval by ANSI ballot. May 1998 A ANSI/EIA-649 initiated by a task to separate the normative principles from the informative material and expand the use of neutral terminology in the industry configuration management standard by ANSI project PN-4
37、766 and approved by ANSI Ballot. Oct 2004 B Revision B was initiated to enhance the standard, and to harmonize with other TechAmerica standards. Revision B is considered an entire rewrite of the standard, so change bar indicators in the margins are not utilized. iv EIA-649-B 1. Introduction Configur
38、ation Management (CM) is a technical and management process applying appropriate resources, processes, and tools to establish and maintain consistency between the product requirements, the product, and associated product configuration information. CM facilitates orderly identification of product att
39、ributes, and: Provides control of product information Manages product changes that improve capabilities, correct deficiencies, improve performance, enhance reliability and maintainability, facilitate interface control, or extend product life Manages departures from product requirements. The term “pr
40、oduct” in this standard should be interpreted as applicable to all product categories; e.g., documents, facilities, firmware, hardware, software, tools, materials, processes, services, systems. A disciplined CM process ensures that the product definition information and changes to that information a
41、re identified, approved, verified, and recorded in sufficient detail to produce and support the product throughout its life cycle; and that the product conforms to the specified requirements. The CM processes result in accurate configuration information to facilitate product interchangeability and c
42、onsistent reproducibility, and thus contributes to continuous safe and effective product development, production, utilization, support and retirement. Although the term “product configuration information” does not specifically include project or administrative types of information; e.g., schedules,
43、plans, and cost information, these and other documents are products and are subject to CM. Appropriate CM functions are applied to manage all information products that can have an impact on product conformance. CM execution requires a balanced and consistent implementation of CM functions guided by
44、CM principles throughout the products lifecycle. The investment in resources necessary to perform effective CM is returned in long term cost avoidance. Significant expenses (e.g., to re-establish the accuracy of product configuration information) are avoided when CM is applied continuously throughou
45、t the products life cycle. Continuous CM application provides authentic approved source information for: Administering warranties Determining liabilities Managing proposed changes Performing maintenance and overhaul Identifying and resolving safety or environmental issues. 2. Scope This standard def
46、ines five CM functions and their underlying principles. The functions are detailed in Section 5. The principles, highlighted in text boxes, are designed to individually identify the essence of the related CM function, and can be used to collectively create a checklist of criteria to evaluate a CM pr
47、ogram. In describing each CM function and its principles, this standard utilizes neutral Configuration Management terminology, while also providing equivalent terms, that have historically been used in various product environments (see Table 2). There is no intent to express preference for any parti
48、cular set of terminology. Similarly, this standard uses a neutral set of names for the phases of a products life cycle, which are generic enough to be easily mapped to the myriad of different life cycle models in use. Table 1 illustrates some of the aliases for each phase name and identifies charact
49、eristics that apply in each one. 1 EIA-649-B Regardless of the titles chosen for these phases, or whether the product is a facility, software, an airplane or a machine screw, at some time in its history a product will go through all or most of these phases. The phases can have considerable overlap, or the sequence of the phases might change or be repeated, e.g., for product improvements and enhancements. Approved
