10. CMMI leads to consistent assessment results and ratings.

7. CMMI is based on the best practices and lessons learned reported from usage of the CMM.

At the 2002 SEPG Conference in Phoenix, Arizona, this question was specifically asked of three of the authors of the original CMM for Software. Their presentation was about what they would have included in the CMM, based on what they now know many years later, having assessed or assisted in many implementations in many organizations. The question posed was based on their discussion: were any of these lessons learned included in the CMMI? Their response was a moment of silence and then a reference to Organizational Innovation and Deployment (OID at Level 5). Although the CMMI purports to include the improvements devised under CMM version 2.0, that statement was also heatedly discussed during the same conference in a later presentation. (Buttons were handed out at this presentation that said, "Free version 2.0.") As a contributor to CMM version 2.0, one of the authors of this book does not see much of a resemblance.
