How to Define CMMI ?

CMMI stands for Capability Maturity Model Integration.

CMMI is a framework of best practices. The current version, CMMI-DEV, describes best practices in managing, measuring and monitoring software development processes. The CMMI model does not describe the processes themselves; it describes the characteristics of good processes, thus providing guidelines for companies developing or honing their own sets of processes.

CMMI currently addresses three areas of interest:

Product and service development — CMMI for Development (CMMI-DEV),
Service establishment, management, — CMMI for Services (CMMI-SVC), and
Product and service acquisition — CMMI for Acquisition (CMMI-ACQ).
