A Component Content Management (CCM) system is a specialized form of content management system that can manage the relationship of all moving parts in association to one another.

Consider an organization that has 10,000 documents that are moving to structured content.  That organization may end up with over 150,000 topics or data modules. Each of those topics or data modules may itself have multiple versions that are moving at different speeds of revision. Furthermore, those topics or data modules may be linked to one another. They also are linked together into a larger grouping (called a map in DITA) or a (DMRL in S1000D). These larger groupings or “table of contents” are themselves changing and versioning. And to add complexity to the whole matter, commercial organizations may need to track language versions of each.

A Component Content Management System is a specialized form of Content Management System that can manage the relationship of all these moving parts in relationship to one another.

A CCM system is to content management what a conductor is to an orchestra.
