Something that's been on my mind lately is how organizational structure influences organizational outcome. Alex (Sandy) Pentland is a really interesting guy to follow in this context and in the context of social dynamics in general. He runs the Human Dynamics lab at MIT and has created a device that can measure subconscious signals of communication (tone of voice and things like that) that can predict the quality of interactions and therefore outcome. He calls them 'Honest Signals'. Take a look at this video where he talks about them.
