When I was in a large org, it was a common failure that a manager would come in from a smaller firm - and assume that our design practices etc. were meaningless overhead.

Inevitably they'd try to do a "rapid prototype" of a feature that had been tried a hundred times before and declared "too hard/unworkable/uninteresting." as they wouldn't talk to those who had done this before, or look at any past work... the invariable result was a project shut down within 6 months and the manager would be shown the door some time later.

The main takeaway from the above is to listen to people around you when you join an org, and observe the habits of successful leaders. Odds are good that at least within this particular org under these circumstances... those habits are the ones that work.
