There is a widespread demand for factual information about the impact and benefits of process improvement based on Capability Maturity Model Integration (CMMI) models. Much has been learned since the Software Engineering Institute (SEI) published a special report on this topic over two years ago. There now is evidence that process improvement using the CMMI Product Suite can result in improvements in schedule and cost performance, product quality, return on investment, and other measures of performance outcome. This technical report summarizes much of the publicly available empirical evidence about the performance results that can occur as a consequence of CMMI-based process improvement. In addition, the report contains a series of brief case descriptions that were created with collaboration from representatives from 10 organizations that have achieved notable quantitative performance results through their CMMI-based improvement efforts. The report is meant for members of engineering process groups, middle and first-line management, and other potential process improvement participants who wish to learn more about how CMMI can contribute to measurable improvements It also may be useful for executives and senior managers who are faced with decisions about the allocation of scarce resources for improvement efforts.

There is a widespread demand for evidence about the impact and benefits of process improvement based on Capability Maturity Model Integration (CMMI) models. Much has been documented about the practice of CMM-based process improvement and its value for the development and maintenance of software and software-intensive systems; however, the existing information is sometimes outdated and there are increasing calls for evidence directly based on CMMI experience. This special report presents selected results from 12 case studies drawn from 11 organizations. While still limited, the case studies provide credible evidence that CMMI-based process improvement can help organizations achieve better project performance and produce higher quality products. The report also describes plans for gathering further evidence from organizations using CMMI models.
