- Everything public in Slack. Create a fun-sounding moto that discourages DMs. Even if a DM happens, and the back and forth resulted in a consensus, share that consensus in a public channel (which makes it searchable).
- Record your team meetings, preferably with software that can AI-summarize. Folks on vacation / leave can get the rundown easily.
- Encourage the sharing of solutions to various problems (technical or otherwise) in Slack. If a developer is stuck, and someone helped them in a huddle or a pairing app, share the solution afterwards (again, makes it searchable). Discourage the over-sharing of screenshots (of your application and other things). Again, not searchable. If one must be shared, describe it. For instance, many devs share a picture of a stack-trace. Not super helpful for others. Grab the text and dump it to Slack.
- Have a good pairing software setup, unblocks for when Slack back and forth is too tedious. I like Tuple (tuple.app).
- Connect your issue tracker to Slack, if you use one, makes creating issues easy. Linear does this well.
- If feasible, have your team meet in person, cadence up to you, but at least once. Meeting the people in real life humanizes them more. I know it sounds silly to say, but it's very true in my experience. Your people will seem even lovelier.
