I'm pleased to share that CMS Watch, Wipro, Hartman Communicatie, and Smigiel Consulting Group have published Version 1.0 of an "Enterprise Content Management Maturity Model," or ECM³ for short. Alan says in the release:

Like all maturity models, it is partly descriptive and partly prescriptive. You can apply the model to audit, assess, and explain your current state, as well as inform a roadmap for maturing your enterprise capabilities.

Like I say, it's a Version 1.0 document. We've released it to creative commons and expect the wider ECM community to "mature" the model itself. Find out more at www.ecm3.org.
