Which of the following defines the scope of CMMI?

The correct choice defines the scope of CMMI as encompassing all processes that affect performance improvement. This broad perspective is fundamental to CMMI as it aims to enhance the capabilities of organizations across various disciplines, not just limited aspects like software development or manufacturing.

CMMI is designed to be applicable across a wide range of industries and practices, reinforcing the idea that performance improvement can stem from many facets of an organization's operations. This includes project management, development processes, service delivery, and any other processes that contribute to overall effectiveness and efficiency. By broadening the scope, CMMI fosters an integrated approach to addressing quality and performance at all levels of an organization, guiding continuous improvement and capability enhancement.

This inclusiveness ensures that organizations can leverage CMMI as a framework to assess and refine a myriad of practices that contribute to their success, rather than focusing narrowly on a single type of process.
