what is the difference between configuration management and change control system

It is noticed that change control system is a subsystem of configuration management system, yet while going through the scope of each system feels that few items of the scope is getting duplicated. In change control system it address more on the effect on deliverables due to changes. Are there are any other differences kindly share?

Yes these two are different functions, yet overlapping do exists. As stated CCS is a subsystem of CM.The major role is being played by CM , starting from documenting of PCR, its initiation by whom, tracing the review and approval praocess, extending the tracking how the changes are incorporated and its effect through integrated change control process. Further updates the configuration status as revised. Coming to CCS its fuctioning basically starts after the change occurence (is it correct) and then the tracking and reviewing continues. Further CCS focus more on the deliverables and documentation of  the change incorporation. This is how we perceived pl clarify

I would technically think of these two things as entirely different functions.  The key elements of configuration management include the identification, labeling, control, status accounting, and auditing of changes.  The change control system is a related function in that it determine what changes will be put through the CM process and which will be tabled.

The question of duplication of effort is an interesting one.  In general, duplication of effort may come from several sources.  One would be a weaker change control system which allows duplicates through the process.  Another would be a configuration management process which does not have a robust means of identifying changes and inspecting them for related activities already in the project pipeline.  Still another source of duplication of effort may be project resources that are not working efficiently.

In general, duplication of effort will have an effect on the efficiency and effectiveness of an organization or project. The CM and CCS processes may need to be reviewed and strengthened.  In addition, the project manager needs to be aware of how work is being carried out.  For example, on a software project, are the developers re-using code or re-writing/developing code.
