I recently had the chance to work with two managing directors of an successful company which has been around for many centuries and which employee base is quiet mature. The 2 MDs have very different views on where the company should head in the future and what to do in order to prepare for that. It reminded me of an pre-web2.0 start-up is was working with, where the managing board consisted of 5 company VPs and the VCs. Operationally one of the problems was that there also decisions where hard to come by. That was because it was hard to get an mutual agreement between the 5 VPs. Mgmt decisions within a start-up should be joint and shared by all members of the mgmt, otherwise you are Hearing for trouble somewhere along the Way in the future. So what is the perfect Number of member of the mgmt? In old as in new companies there seems to be a trade off between speed of decisions and involvement.
