> By reducing the size of our team, fewer conversations will be required to make a decision
This was noted a long time ago by Brooks in the Mythical Man-Month. Every person added to a team increases the communication overhead (n(n − 1)/2). Teams should only be as big as they absolutely need to be. I've always been amazed that big tech gets anything done at all.
The other option would be to have certain people just do the work told to them, but that's hard in knowledge based jobs.
