Information on Change Management
Changes to configuration items will occur throughout the project caused
by a range of event such as changes in a
requirement, changes in available technologies and products, and so on.
These changes need to be managed by a formal change
management process to ensure impacts are investigated and
handled appropriately. Change management is therefore an important
part of configuration management.
Within a change management system,
changes are classified by severity: Class 1 changes are major
changes and involve form, fit or function; and Class 2
changes are minor changes such as documentation update and material
substitution. In most change management systems, customers must
be involved in agreeing to Class 1 changes but will
normally only be informed of Class 2 changes. Other change
management systems are often implemented with more than
two classes, but at least two classes are required for
a useful configuration management system.
