One extremely common pitfall is that attempts to build dev teams in non-tech companies end up creating a clique of "big thinkers" who unfortunately can't code much themselves. They end up convincing the management to contract out the lowly work and essentially become middlemen to other people's work. You possibly can avoid that via good hiring policy if you know what you are doing. However once you quit the chance of things deteriorating is huge.
