How to ruin a great team

In following through How to ruin a great team, you will find a great piece about what not to do when you take over a team (soccer, in this case). The two main points I got from the original article is that a manager must be able to communicate and must be able to adapt to the culture of the team (instead of imposing his own from the start).

I believe this to be true whether you are talking about a sports team or a software/system development team!
