significantly reduce the time to achieve compliance. SEI has maintained statistics on the "time to move up" for organizations adopting the earlier
Software CMM as well as CMMI. These statistics indicate that, since 1987, the median times to move from Level 1 to Level 2 is 23 months, and from Level 2 to Level 3 is an additional 20 months. Since the release of the CMMI, the median times to move from Level 1 to Level 2 is 5 months, with median movement to Level 3 another 21 months. These statistics are updated and published every six months in a maturity profile.

best practices. Of these, class A appraisal is the most formal and is the only one that can result in a level rating. Appraisal teams use a CMMI model and ARC-conformant appraisal method to guide their evaluation of the organization and their reporting of conclusions. The appraisal results can then be used (e.g., by a process group) to plan improvements for the organization.
