As an XP guy, I’m a big fan of pair programming.
(Somewhere I have slides of coworkers pairing: I should find them and post them.)
I’ve also had great success with coding dojos that focus on pairing.
(Interesting: locally there are dojos for kids that need mentors. I might apply…)
However, I’ve never really had more than two people coding on the same screen.
Apparently mob programming is now a thing.
Here is a book, and here are some slides from Rachel Davies.
I can’t wait to try this, and to see if I can coach others to try this technique.
