DefinitionConfiguration management (構成管理) is the process of identifying the configuration items that make up a service, such as equipment, software and procedure manuals, and keeping their information accurate and up to date.
ExplanationA configuration item is each individual part of a service registered as something to be managed, with its version, location and links to other items recorded. These records are gathered in the configuration management database (CMDB) and serve as the reference when checking the impact of a change or tracing the cause of a failure.
AnalogyIt is like a library catalog. Only when it correctly shows which books sit on which shelf, and how many copies there are, can you plan replacements or repairs.
Memory hookThe Japanese name 構成管理 literally means "composition management": it writes down how the parts are put together. Configuration carries the same sense of an arrangement of parts.
