SEI has produced a number of models that focus on process improvement
Capability Maturity Models® (CMMs®) assist organizations in maturing their people, process, and technology assets to improv long-term business performance. The SEI has developed CMMs for software, people, and software acquisition, and assisted in the development of CMMs for Systems Engineering and Integrated Product Development.
Software engineers trained in the Personal Software ProcessSM (PSPSMmake accurate and realistic estimates and then routinely produce on schedule, with reduced development time and significantly reduced numbers of defects in delivered code.
The Team Software ProcessSM (TSPSM) builds on the foundations of the CMM and PSP to guide organizations in forming and managing high-performance integrated product teams.
