The CMMI for Development (CMMI-DEV) is probably the best known CMMI model. This is the de-facto standard for quality engineering throughout the world.

CMMI for Devlopment is aimed at organizations that perform engineering work, any type of engineering work, and are organized in projects. The evolutionary scale of the CMMI model allows elementary or foundational practices to be implemented first, then build on the lessons learned from these practices for continuous improvement throughout an organization.
