Pair programming is the practice you love to hate! It's been nearly twenty years since Extreme Programming promoted pair programming as a collaborative practice, and it's still here. And if you thought that was bad, now there's mobbing, where the entire team works together on one thing at a time. Does that seem nuts? Yet we often hear teams say, "We go faster because we are mobbing." In this anecdote-heavy session, you'll hear Jeff Langr's history of working through various models for collaboration (or not) across the past several decades, including pairing, solo programming, and mobbing. He'll show you his office blueprints to help put you in his shoes and understand what made for the ups and downs of each model. You'll learn tips for success with each model, pitfalls to watch out for, and Jeff's take on why mobbing or pairing might help us go faster.
