Statistical evidence has shown that programmers perform better when following a defined, repeatable process such as the Personal Software Process (PSP).Anecdotal and qualitative evidence from industry indicates that two programmers working side-by-side at one computer, collaborating on the same design, algorithm, code, or test, perform substantially better than the two working alone i.e. pair programming. Bringing these two ideas together, a new Software Process has been formulated. The Hybrid Personal Software Process (HPSP) is a defined, repeatable process for two programmers working collaboratively. The development time and cost of the product are reduced in HPSP when compared with PSP programming.
