A study was conducted by the SEI (now CMMI Institute) on the metrics data collected from 35 large organizations across the world. These organizations having low as well as high maturity apply CMMI Process Improvement practices to their Software Engineering, System Engineering and other Engineering activities.
In this study Global Software Group (GSG) of Motorola India Electronics had grown to a staff size of 2400 employee in year 2006 which were triple to its size of 800 employees in year 2003. This was observed after initiating and maintaining CMMI Process Improvement activities in the organization.
Figure: Phase Containment Effectiveness
After the CMMI Initiative the Audit Process was automated and as a result the Non-Compliances found in the Process Audits were higher compared to earlier audits of same duration. In year 2005, the 412 non-compliances in 50 audits conducted over a period of three-months. In earlier audits of same time frame, only 109 non-compliances were found in 82 audits. It was contributed to the improve Audit Methodology adopted as a result of CMMI Implementation.

Following quantitative benefits were observed with respect to different defects related metrics:
All this was attributes to the CMMI Process Improvements activities like improved Verification and Organizational Training process areas.
Figure: Cost of Quality
It was also observed that the Cost of quality (COQ) got decreased by 15 percent. It was attributed to the automation done after the institutionalization of processes related to the Verification, Validation, and Organizational Innovation and Deployment process areas
Customer Satisfaction Surveys ratings have increased from an average of 8 (very good) to 9 (excellent) out of 10. This shows an improvement in the customer satisfaction and lesser number of defects in deliveries.
This shows that CMMI Process Implementation can lead to effective audits, lesser defects, higher phase containment rate of defects, reduced cost of quality, improvement in customer satisfaction and product quality.
