Tata Consultancy Services (TCS) is a large information technology consulting, services, and business process outsourcing organization interested in reducing the costs of conducting process improvement appraisals at its multiple locations. TCS initiated a pilot to determine whether appraisals could be performed at the enterprise level instead of at each location or center while preserving the integrity of the Standard CMMI® Appraisal Method for Process Improvement V1.1 (SCAMPISM V1.1). The pilot was also used to determine whether a single type of appraisal could be effective in an organization compliant with multiple models.
A pilot Class A SCAMPI appraisal for the People Capability Maturity Model® (People CMM®) was performed jointly with a Class A SCAMPI appraisal for Capability Maturity Model Integration (CMMI) across TCS in 2004. This report includes the draft interpretation guide used for four mini-appraisal pilots and the final enterprise-wide Class A appraisal at TCS. The information in this report could serve as an example for other organizations and is fully applicable to any size SCAMPI appraisal with People CMM.
