XP Game

Today couple of my colleagues conducted XP Game for those of us who had joined ThoughtWorks recently. It was fun. Visit this link for more on the game. We were divided into small teams of 5-6 people and played the role of developers and customers in turns. We estimated the tasks as developers and prioritized the same as customers. We played a couple of iterations and believe me, it was fun. Some observations from this exercise:
1. We were aggressive in our estimates in the first iteration.
2. The second iteration was drastically different and better in estimates as well as implementation due to the lessons learnt in the first iteration.
3. Tasks in the later iterations which were similar to the earlier ones were done almost exactly on time.

Overall, it was fun way of learning XP concepts like velocity, estimation etc.
