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.
