Quite a Problem

Problematic pair programming "There's a joke that pairs, like fish and house guests, go rotten after three days," said Zach Brock, an engineering manager. Working out problems with a pairing partner can be a lot like working out problems with a significant other. During one recent rough patch, Jamie Kite, a developer, sat her partner down for a talk. "Hey, it feels like we're driving in different directions," she recalls saying. "It's like any relationship," Ms. Kite said. "If you don't talk about the problems, it's not going to work." When those timeouts don't solve the problem, partners can turn to on-staff coaches who can help with counseling. "People who have been pairing a while, they'll start acting like old married couples," said Marc Phillips, one of the coaches. People can be as much of a challenge as writing software.
