form the basis of configuration management. A configuration item, or CI,
is a unit of configuration that can be individually managed and versioned. In
other words, "configuration item" is often used to refer to an item, which is
then said to be produced in several versions. This is not strictly correct, but
it's acceptable as long as the reference is clearly understood by all involved.
In fact, each new version of a configuration item is a new configuration item in
its own right.
Typically, a configuration
management system will control files, requirements, or another definable unit.
These units are managed with a combination of process and tools to avoid the
introduction of errors and to maintain high quality results. The units
themselves can be considered configuration items, or they may be combined into
an overall collection that is managed under the same set of processes and tools.
