If you have reviewed or used a CMMI model before, you will quickly recognize the CMMI concepts discussed and the best practices presented. The differences between version 1.2 and version 1.1 are explained in detail on the SEI Web site in the version 1.2 release notes. These differences reflect the enhancements suggested by the users of version 1.1.

The following improvements were made to version 1.2:

·   Both representations are presented together.

·   The advanced practice and common feature concepts have been removed.

·   The generic goal and practice descriptions were moved to Part Two.

·   Hardware amplifications were added.

·   All definitions were consolidated in the glossary.

·   IPPD practices were consolidated and simplified. There are no longer any separate IPPD process areas.

·   Supplier Agreement Management (SAM) and Integrated Supplier Management (ISM) were consolidated and Supplier Sourcing was removed.

·   Generic practice (GP) elaborations were added to the level 3 GPs.

·   An explanation of how process areas support the implementation of GPs was added.

·   Material was added to ensure that standard processes are deployed to projects at their startup.
