A FRAMEWORK FOR SOFTWARE PROJECT MANAGERS TO QUANTIFY THE COST EFFECTIVENESS OF EXTREME PROGRAMMING PRACTICES
S. Kuppuswami, K. Vivekanandan, Paul Rodrigues · 2003
XTREME Programming practices (Xp) is new, innovative and revolutionary software development practices that are being adopted by software companies. Even though the benefits of the Xp are qualitatively discussed, many project managers are reluctant to apply these practices in real projects due to the lack of quantitative proofs. Improvement in productivity of software development is claimed to be one such benefit of the Xp practices. The present research is undertaken to measure the change in software development productivity when the Xp practices are applied. The change in productivity is to be computed by including the other factors that influence productivity. In this paper we propose a framework to measure the effect of extreme programming practices on software development productivity. This framework includes a data analysis and a data collection method. The research model uses multiple linear regression technique as the data analysis method. The above framework was applied and found there is minimum of 25.5 % change in productivity for a change in one level usage of extreme programming practices.
