We mistakenly think of brainstorming as something you can do in meetings, and teaching as something you can perform through carefully composed documents or lectures. I was part of a number of failed remote R&D attempts. The one time it worked was when we decided to abandon meetings, project documents, tracking tools, etc. Instead, we got a high quality speakerphone so everyone could overhear everyone else’s conversations, and we left it on all day, every day. It wasn’t the same as being together in person, but we did manage to get some of the human friction back.
