I've wondered what the "optimal" team size is of direct reports to manage. I read a Fortune article a while back that stated some research suggested a team of 6 to 7 is the best. Except for short term projects, I've never managed a team that small. The smallest group was around 10 and I've managed up to 24. I can definitely say 24 is way too big. There's no way to keep track, coach, manage, feedback, one on one, etc. that many people. Personally I've felt under 14 was best for me. Any thoughts out there?
