TechRepublic interviewed Bill Bumgarner about CodeFab's use of eXtreme Programming. I'm a big believer in XP. Unfortunately I haven't been able to work in a shop that truly embraced it.

TechRepublic: A development shop turns to XP to take on the cost of change

Whenever I talk to people about XP they always poo-poo pair programming. Every time I've had a chance to do it I've been absolutely sure it's worth it. Bill very clearly explains why it's a good thing. I can't understand managers who don't think it's important to spread the knowledge of a project among the entire development team. I think insulating developers in silos of knowledge and experience is a fatally-flawed approach.
