Agile methods and user-centred design: the original debate
The issue of integrating agile methods and user-centered design has been discussed for several years, although interest in the CHI community has now lessened. There is a lot of information about agile methods available on the Internet, but less is written concerning the integration of these two approaches. However there is a yahoo discussion group at http://groups.yahoo.com/group/agile-usability. One popular agile method is eXtreme Programming (XP), and a good starting point to find out more about XP is www.extremeprogramming.org. Also see the Connextra case study on this site. Background information about agile methods is at http://www.martinfowler.com/articles/agileStory.html
