I believe it all starts with the right people. If you have the right people in your team, i.e. open minded, willing to learn and improve etc., they will naturally tend to perpetuate the right kind of environment.

In this situation you have to first build a whole lot of trust among the team members and management before trying to slowly introduce ideas like this. Often projects finish before such a level of trust can be established.
