By gathering requirements on story cards extreme programming (XP) makes requirements collection easy. However it is less clear how the story cards are translated into a �finished product. We propose that a formal specification method based on X-Machines can be used to direct this transition. Extreme X-Machines �t in to the XP method well, without large overheads in design and maintenance. We also investigate how such machines adapt to change in the story cards and propose how this could be further enhanced
