Back in the 1980s, the United States Air Force wanted to evaluate its contractors so it funded a research at CarnegieMellonUniversity’s Software Engineering Institute (SEI) to create a model. The outcome was the Capability Maturity Model (CMM), which was originally published as the Managing Software Process in 1989.
In 1997, the Under Secretary of Defense (OUSD) initiated a review of SEI activities and the Capability Maturity Model Integration (CMMI). Over the years, many organizations have benefited by adopting the CMM model and achieving one of its five maturity levels. Experts say that the overall return on investment of implementing CMM could be as high as 15-to-1, as the process improvement increases the overall productivity of the organizations.
Moving up the CMM maturity levels brings major performance improvements, including improved stakeholder and customer satisfaction, improved quality and robustness of deliverables and products, shortened and more predictable delivery times and cost reductions. By moving from CMM maturity level 5 to CMMI level 5, Siemens Information Systems Ltd. was able to reduce the cost of poor quality from over 45 percent to less than 30 percent.
Tata Consultancy Services reported over $4.6 million in savings across all development centers by achieving CMMI maturity level 5. Boeing reported 12 percent in cost savings from an earlier
