Your development team will become much more efficient than you thought possible. At some point you will find that the XP rules no longer seem like rules at all. There is a synergy between the rules that is hard to understand until you have been fully immersed. This up hill climb is especially true with pair programming, but the pay off of this technique is very large. Also, unit tests will take time to collect, but unit tests are the foundation for many of the other XP practices so the pay off is very great.
People move about, asking each other questions and trading partners for programming.
People spontaneously meet to solve tough problems, then disperse again. Encourage this interaction, provide a meeting area and set up workspaces such that two people can easily work together. The entire work area can be open space to encourage team communication. Copyright 1999 J. Donovan Wells all rights reserved.
