Configuration management is for most of time dealing with the system that is large, complexed, has a long life duration (more than 10 years) and involve more people. The key issues for engineering support are to coordinate the participants and to provide each engineer an environment, also called a workspace where they can work independently in the task duration. The former one refers the cooperative work support and the latter one is mostly called workspace support.
