Enterprise Content Management (ECM) as a unifying concept is relatively new. ECM is based on the integration of a set of technologies each of which is still evolving. Not surprisingly, research is scarce and the market is still consolidating. As a result, integral ECM implementations are still rare.It is argued that, pending the widespread adoption and implementation of ECM, much can be learned from experiences with the implementation of Enterprise Resource Planning (ERP) software.Another reason for taking these experiences seriously is the growing extension of ERP-products with ECM-functionality. This extension may eventually result in an ERP-driven ECM-implementation or even in combined ERP/ECM products.Lessons learned from the implementation of ERP are that implementations may be compromised by a large number of legacy issues. It is argued that the same issues may similarly affect the implementation of ECM. Therefore, it is advised, with due adaptation, to take these issues into account in devising implementation strategies for ECM.
