If you are trying to get your arms around your SharePoint implementation, decide where to invest, and demonstrate progress, the SharePoint Maturity Model framework can help you. I developed it as a veteran of over 50 SharePoint implementations, and it has been vetted and refined by experts around the globe. It will evolve as the product evolves, and it will guide your implementation through its own evolution, providing direction to the iterations and phases that lead to a mature solution.
