Comparison with waterfall model

What is extreme programming

Extreme Programming (XP) is a software development methodology created by Kent Beck during his work on the Chrysler Comprehensive Compensation System (C3) payroll project. Extreme Programming is intended to improve software quality and responsiveness to changing customer requirements. It is a one of the several types of agile software development processes. Extreme Programming is successful because it stresses customer satisfaction. Instead of delivering everything you could possibly want on some date far in the future this process delivers the software you need as you need it. Extreme Programming empowers developers to confidently respond to changing customer requirements, even late in the life cycle. Back to top

Research Conclusion

Research was carried out in Carnegie Mellon University where data collected was from five years of 50 teams, developing the same project each year and the affects of transitioning from Waterfall to Extreme Programming was analyzed. The characteristics between these two methods were evaluated and compared. According to the paper, waterfall teams spent more time creating high ceremony documents where as Extreme Programming teams spent more time writing code and documenting their design in their code.  Surprisingly, the amount of code and features completed were roughly the same for both methods suggesting that on a three month project with three to four developers it didn't matter the method used. Please refer the references for the research paper.
