26、relating to the execution of an operation or function; e.g., quantity (how many or how much), quality (how well), coverage (how much area, how far), timeliness (how responsive, how frequent), and readiness (availability, missiodoperational readiness). phvsical attributes: Quantitative and qualitativ
27、e expressions of material features; e.g., composition, dimensions, fiiishes, form, fit, and their respective tolerances. product : Something that is used or produced to satisfy a need or is the result of a process; e.g., documents, facilities, firmware, hardware, materials, processes, services, soft
28、ware, systems. product attribute(s): Performance, functional, and physical characteristic(s) of a product. product configuration information: Information about a product consisting of product definition information and product operational information. product definition information: Information that
29、 defines the product requirements, documents the product attributes and is the authoritative source for configuration definition and control. product identifier: A name or alphanumeric identifier, unique to the issuing organization, used to designate products of the same configuration, and to differ
30、entiate them from other products. product operational information: Information developed from product definition information and used to test, operate, maintain and dispose the product. product structure: A hierarchical view of the relationship of products and component products. release (hardware):
31、 Authorization for dissemination of approved information and/or products subject to configuration change management. release (software): A particular version or revision of a software product that is made available for a specific purpose (for example, test release). 8 Copyright Government Electronic

CM planning should be re-evaluated following significant change affecting the context and environment, e.g.,
39、 changes in suppliers, or supplier responsibilities, changes in resource availabilities, changes in buyer contract, changes in the product. CM Planning should also be reviewed on a periodic basis for organizations in a sustaining mode to make sure that their application of CM functions to their orga
40、nization is kept current. 5.1.2 Document CM Planning Perform CM planning and document it. The form and format of the planning documentation; e.g., included with other project planning or included in a stand-alone CM plan, is not critical. However, execution of Configuration Management per the planni
41、ng documentation is critical for successful CM process implementation. 5.1.3 Assign Responsibility and Apply Adequate CM Resources It is necessary to plan and implement Configuration Management as a product flows through its life cycle, and it is essential that adequate resources be applied to maint
42、ain the needed controls and consistency. Resources are identified and assigned to perform the activities identified in CM planning. The required resources may include personnel, 13 Copyright Government Electronics - Released information has been reviewed and authorized for use or, if required, has b

A new version cannot replace a released version until it has also been reviewed and authorized. The configuration of a document is fixed once it is in the released state and is o
44、nly changed by release of a superceding revision; - Archived information is released information (reviewed and approved) that is no longer authorized for continued use. It is kept as an historical record for reference purposes (e.g., redesign, failure analysis, regulatory requirements, etc.). Ensure
45、 delivered product configuration information is complete and appropriate for the users computing environment. The product configuration information should be acceptable to the user whether the exchange is by physical media, electronic data exchange, web access, or other means. When data are provided
46、 in floppy disks, tapes, CD-ROM, or other physical media, appropriate identification is affixed to the media to clearly identify the configuration of its contents. When it is impracticable to include all of the file identifications, a reference to an accompanying list, or to a “Read Me” file, should
47、 be created and tendered as part of the media. 5.1.9 Planning for Data Preservation The life cycles of the product, the information technology used to interpret the data, and the storage media are considered when planning for preservation of data. - Product: To determine what data must be retained a
