How Can CMMI Benefit You?

Today, CMMI is an application of the principles introduced almost a century ago to achieve an enduring cycle of process improvement. The value of this process improvement approach has been confirmed over time. Organizations have experienced increased productivity and quality, improved cycle time, and more accurate and predictable schedules and budgets [Gibson 2006].

The benefits of CMMI have been published for years and will continue to be published in the future. See the SEI website for more information about performance results.

Although the cost of CMMI adoption is highly variable depending on many factors (organization size, culture, structure, current processes), regardless of the investment, history demonstrates a respectable return on investment.

Example returns on investment at various organizations using CMMI for Development (CMMI-DEV) include those shown in Table 1.1.

Since the CMMI-SVC model has been recently released, data on the results of its use are not yet available. The SEI will be collecting ROI data as organizations adopt the CMMI-SVC model.

See the CMMI website (www.sei.cmu.edu/cmmi/) for the latest information about CMMI adoption, including presentations by those who have adopted CMMI and want to share how they did it.
