PSP0: You establish a measured performance baseline

PSP1: You make size, resource, and schedule plans

PSP2: You practice defect and yield management

PSP3: A Cyclic Personal Process

10.3 THE TEAM SOFTWARE PROCESS (TSP)

Using PSP3, programs can be built with more than 10 KLOCs. However, there are two
problems: First, as the size grows so does the time and effort required, and second,
most engineers have trouble visualizing all the important facets of even moderately
sized programs. There are so many details and interrelationships that they may
