When the University of Pittsburgh Medical Center adopted Capability Maturity Model Integration, it benchmarked its performance in developing interfaces between key high-volume, data-intensive health and patient management systems. In mid-2004, it took 160 hours to design the interface and 214 days to deliver it. Those numbers plummeted to 107 hours and 109 days by early this year. Before implementing CMMI, the interface development team's performance in meeting the model's best practices was inconsistent. The team generally performed best practices about 30% of the time, partially performed 40% of the time, and failed to perform 30% of the time. Today, it meets best practices more than 90% of the time.
