Benefits of CMMI

CMMI provides guidance for efficient, effective improvement across multiple process disciplines in an organization.

It benefits the organization by providing a common, integrated vision of improvement. The ultimate benefit is improved performance that means decreased costs, improved on-time delivery, improved productivity, improved quality, and improved customer satisfaction.

Another benefit is return on investment. Such a program more than pays for the monetary investment required. These are all reasons why CMMI is the choice for process improvement in multiple industries.

Below are some examples of the benefits to real-world companies:
