Enterprise Content Management is the systematic collection and organization of information that is to be used by a designated audience – business executives, customers, etc. Neither a single technology nor a methodology nor a process, it is a dynamic combination of strategies, methods, and tools used to capture, manage, store, preserve, and deliver information supporting key organizational processes through its entire lifecycle.
Document management eventually was subsumed into content management in no small measure because there is more information available to us today than ever before, and most of it is not being created by us.
Effectiveness, efficiency, compliance, and continuity all combine, in different proportions, to drive the business case for content management in most organizations.
