- maturity model (p.191): CMM/CMMI is the collective term for two models: CMM, and CMMI. CMM is a formal model that contains only the software engineering discipline. As successful software development should include not only software engineering, systems engineering, but also people (including suppliers) and process management. Therefore, all of the required disciplines are comprehensively integrated into one model, that is, CMMI, in which “I” stands for integration. The process focused CMM/CMMI suggests that sustainable software development relying on processes that define and manage software development. In this regard, the CMM/CMMI identifies sets of recommended practices in a number of key process areas that comprehensively cover the lifecycle of technical software development and both the organization and project level of managing the development. (†1460)
- maturity model (p.191-192): Specifically, in CMM/CMMI, process area (PA) is a cluster of functionally related practices. Each process area has Specific Goals (SGs) which must be satisfied, and each SG contains several Specific Practices (SPs) for achieving the SG. The aforementioned process areas and their process ingredients tell software organizations what to do in implementing quality software development. In order to help organizations to sustain their process implementation continually, CMMI/CMMI has established a concept that is called “Level of Institutionalization”. In the models of CMM/CMMI, institutionalization of process implementation has different levels, each level must be satisfied by achieve their Generic Goal (GG) and Generic Practices (GP). (†1461)
- maturity model (p.192): The usage of CMM/CMMI has two representations, continuous and staged. If an organization would like to concentrate on a particular process area, they may choose the continuous representation of CMM/CMMI. In this case, the continuous representation uses capability levels to characterize the state of the organization’s processes relative to individual process areas, and provides a recommended order for approaching process improvement within each specified process area. If organizations would like to receive a collective result, they may choose the staged representation of CMM/CMMI. The staged representation focuses on overall maturity as measured by maturity levels, and uses maturity levels to characterize the overall state of the organizational performance relative to a set of related process areas as a whole.
