Physical Configuration Audit
In computer engineering, a physical configuration audit (PCA) is the formal examination of the "as-built" configuration of a configuration item (CI) against its technical documentation to establish or verify the CI's product baseline. The PCA is used to examine the actual configuration of the CI that is representative of the product configuration, in order to verify that the related design documentation matches the design of the deliverable CI. It is also used to validate many of the supporting processes that the contractor uses in the production of the CI. This is also used to verify that any elements of the CI that were redesigned after the completion of the functional configuration audit also meet the requirements of the CI's performance specification. Additional PCAs may be accomplished later during CI production if circumstances such as the following apply: * The original production line is "shut down" for several years and then production is restarted. * The production contrac ...

Configuration Item
The term configuration item (CI) refers to the fundamental structural unit of a configuration management system. Examples of CIs include individual hardware or software components. The configuration-management system oversees the life of the CIs through a combination of processes and tools by implementing and enabling the fundamental elements of identification, change management, status accounting, and audits. This system aims to avoid the introduction of errors related to lack of testing as well as of incompatibilities with other CIs. Description The term "configuration item" can be applied to a product, allocated component of a product, or both that satisfies an end use function, has distinct requirements, functionality and/or product relationships, and is designated for distinct control in the configuration-management system. Configuration items and their associated product configuration information versions, and approved changes, form the basis of any current approved configu ...

Software Configuration Management
In software engineering, software configuration management (SCM or S/W CM) is the task of tracking and controlling changes in the software, part of the larger cross-disciplinary field of configuration management. SCM practices include revision control and the establishment of baselines. If something goes wrong, SCM can determine the "what, when, why and who" of the change. If a configuration is working well, SCM can determine how to replicate it across many hosts. The acronym "SCM" is also expanded as source configuration management process and software change and configuration management. However, "configuration" is generally understood to cover changes typically made by a system administrator. Purposes The goals of SCM are generally: *Configuration identification - Identifying configurations, configuration items and baselines. *Configuration control - Implementing a controlled change process. This is usually achieved by setting up a change control board whose primary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
