The document summarizes the Team Software Process (TSP), which is a disciplined engineering practice developed by the Software Engineering Institute to produce reliable software in less time and at lower costs. TSP focuses on improving team performance through self-directed teams, integrated measurements, and quality reviews. Studies have shown that organizations using TSP achieve improvements in schedule, cost, productivity, and quality, including reducing post-release defects by 80% and balancing schedule and cost variances between -20% to 20%. TSP provides training and tools to implement the process over the course of about a month. A growing number of companies and government organizations have adopted TSP.
