Foley-
Jeff is right, there is such a thing as too much organization. My opinion is that you should build the organization around the goals that your team has set - don't build the organization before setting the goals.
If people are getting hung up on their job title it can sometimes be a problem - maybe "responsibility" is a better way to think of it than "title."
One idea that I think is very important is to CLEARLY define what responsibilities people have, and DON'T make two people jointly responsible for something. If one person is responsible, they don't need to have a meeting/discussion/argument to make a decision (unless, of course, they are schizophrenic, but thats an entirely different problem
).
hth,
