The Team Software Process Body of Knowledge (TSP BOK) was drafted to define the fundamental knowledge and skills that set TSP-trained individuals apart from other software professionals. It helps individual practitioners to assess and improve their own skills, provides employers with an objective baseline for assessing the process improvement skills and capabilities of their development team members, and guides academic institutions that want to incorporate TSP into their software and other engineering courses or curricula. The TSP BOK also facilitates the development of TSP certification programs that are based on a well-established standard set of knowledge and skills.
