Software quality is growing in importance: we are increasingly dependent on software for everything from transportation to public safety. The Carnegie Mellonreg Software Engineering Institute has pioneered excellent methods for software process improvement, namely its capability maturity model integration (CMMIreg) and Team Software Processtrade (TSPtrade). This paper provides a brief overview of software quality and its history, a short treatment of CMMI, and an introduction to the TSPtrade , the SEI's "how to" guide to achieving process maturity. Empirical results are presented.
