The CBA IPI method was developed and field tested in 1994. After factoring in lessons
learned from the community feedback, the SEI released CBA IPI V1.0 in May 1995. The
method and documentation were upgraded to CBA IPI V1.1 in March 19962. The CBA IPI
method explicitly uses CMM V1.1 as a reference model. The data collection is based on key
process areas (KPAs) of the CMM as well as non-CMM issues. CBA IPI is intended to establish
consistency among CMM-based assessments so that results from one assessment can be
compared to those of another. The CBA IPI method complies with the CAF, so results from a
CBA IPI are intended to be consistent with results from other CAF-compliant methods. The
CBA IPI method is described in more detail in the following sections of this report. Appendix
B contains descriptions of the method roles and responsibilities, while Appendix C contains a
glossary of terms commonly used in a CBA IPI.
