CMMI and TSP/PSP: Using TSP Data to Create Process Performance Models

This report describes the fundamental concepts of process performance models (PPMs) and describes how they can be created using data generated by projects following the Team Software Process (TSP). PPMs provide accurate predictions and identify factors that projects and organizations can control to better ensure successful outcomes, helping organizations move from a reactive mode to a proactive, anticipatory mode. PPMs are fundamental to the implementation of the high maturity process areas of Capability Maturity Model Integration and are specifically required in the Quantitative Project Management and Organizational Process Performance process areas. The three examples in this report demonstrate how data generated from projects using TSP can be combined with data from other sources to produce effective PPMs.
