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 (SCAMPI 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.
