Change management is, among other things, a management aspect of project management. The term change management is also used in automotive engineering as engineering change management( ECM) and in network management.
The context discussed here is about one aspect of project management. It is about change requests and the modification of documents and deliverables or changes to the baseline plan. It is about organizing and managing changes that are identified, documented, approved, or rejected during project execution. Change management involves all project team members and carefully records all changes so that they can be followed up in detail by the team members. On some projects, changes are investigated and approved only by the Change Control Board( CCB).
