It isn’t just pair programming that is really useful. I had a problem that I found horrendously complicate to resolve, and I got on the phone with the rest of the team, trying to explain to them what I wanted and how I wanted to achieve that.
Luckily for me, they were too polite to tell me that I am being stop and that I should stop whining. But they were able to guide me toward an elegant solution in about fifteen minutes. Until at some point I had to say: “I really don’t understand why I thought this was hard.”
Getting feedback is important, be it on code or design.
