Given the competition and the urge to become a major player, companies need to adopt the Personal Software Process (PSP) and Team Software Process (TSP) than that of merely achieving the quality levels of CMM and Six Sigma, said Watts Humphrey, quality guru and propounder of the benchmark Computer Maturity Model (CMM).

Mr Humphrey, who is also the Fellow of Software Engineering Institute atthe Carnegie Mellon University, said that both PSP and TSP will immensely benefit software professionals. They not only fix the bugs with a consistent zero defect delivery system but also will make the corporates be more competitive and withstand all competition.

Mr Humphrey, who was here on a visit to address the software professionals and industry captains, said that PSP is an individual level model that helps individual engineers to plan their work, estimate the size, defects, effort and schedule involved in their work and to track these while working. It has been found that errors have come down sharply and the defects rate go down to less than one in 10,000 lines of code and the overall productivity increases by an order of magnitude, Mr Humphrey said further.

According to him, TSP helps teams (members) to be self-directed, to formulate team goals and to provide a framework that supports team members in achieving the goals to which they are committed. Industry results show that projects carried out in this manner have registered a dramatic fall in delivered defects, very good predictability of effort and schedule and great improvement in team productivity.
