Pair programming is a technique about which we hear a great deal. But how do you prepare someone to pair-program? How does someone learn to deal with the inevitable disagreements and relative strengths and weaknesses? Dan Quan is not just a software developer, but also a former policeman. In this talk, he describes how police work provided an excellent introduction to how pairing can and should work. How do you divide labor between partners?  How can (and should) you depend on your pair?  What do you communicate to your pair before you start work for the day?  If you are interested in pairing, then this talk should help you to prepare better and to understand what’s involved.
