This chapter is based on our experience while working for a software outsourcing company that was built around the XP methodology. One of the difficulties we had in adopting XP was that the original "white book" (Extreme Programming Explained), though inspiring and persuasive, was somewhat short on detail. We feel that it would be valuable to the XP community if groups doing real projects would provide detailed accounts of their experiences in applying XP. Finally, some issues took on additional significance for us because our client had outsourced their project to us.
