Detailed Plan

10. CMMI leads to consistent assessment results and ratings.

The SCAMPI method using the CMMI has the same problems as the previous assessment methods using the CMM ” that is, the make-up of the team members and their individual experiences will flavor their interpretations of the model and their interpretations of the implementation of the model in the assessed organization. As discussed previously, SCAMPI teams are having trouble interpreting the practices. They refer to the explanations in the practices in the model and come up lacking. So, most teams have reported simply using their own experiences to interpret the meaning of the practices. While we do not want a book that mandates how to improve our organization, we still need more information on what the details mean. Without this guidance, we see no guarantee that this model supports more consistent results and ratings than the previous model. In fact, with the lack of explanations and examples, we see this model leading to even more inconsistent results.
