Will take a look on this, thanks. Your article also reminded me of the one from Marshal Goldsmith - Leadership is a contact sport http://www.strategy-business.com/article/04307?gko=a260c

It 's based on study done to large companies, but the insights are relevant to everyone. In a sense, what the study concluded was that the teams who had the best communication habits had better results (he then describes what those communication habits are) A summary is in the video : https://www.youtube.com/watch?v=Xxwjo-Ne9C8

Again, this is oriented to big cos and HBR readers, but in this case the insights can be applied to everyone. Good stuff.
