I did a talk to a team at work yesterday about #PairProgramming. They’ve been trying it out, but they’re all new to it, so I recommend @LlewellynFalco’s Strong Style Pair Programming. But while I was digging out some references, I came across this: scribd.com/doc/25304465. It talks about the hit that engineers get from tinkering with code until it works, then moving on.
