Does Complexity Facilitate Vision?

Andy Stanley had an interesting quote at the Catalyst Conference (h/t Mark Beeson),

The more complex your church government, the more that complexity will war against your vision.

That’s a pretty simple statement, and we could qualify and debate it all day long.  However, I just want to pose a question.  Does the complexity of the United Methodist Church facilitate its vision or compete with it?  What about in local churches?  What do you think?
