Yes, you still should get together in the same room.
You need human interaction. You need whiteboard sessions. You need to shoot the crap. You need to sit around a conference table and haggle over some stuff. You need to shake hands.
It’s about more than work; it’s about building a cohesive unit.
You need regular, if infrequent, get-togethers. Not every day or every week, but find the rhythm that works with the team and within your budget. That rhythm may change as the arc of the project changes.
With my current team, we would gather about every four to six weeks for a few days to a week. As we got to know each other better, we found that once a quarter or so works well for us now.
When you get together, don’t expect to work the same way or even do the same kind of work that you do when you’re sitting in your home office. That time together is all about being together. Use it to do the things that are a hard remotely. The watercooler conversation may be the most important piece. Let it be.
Maybe it’s once a month for you, or maybe once a year. Find the rhythm that works for you and your team. Once you do, you’ll be unstoppable.
