I define "corporate" as any human org greater than 100 members, including non-profits, academia, military, even your damn scout troop.
Also: never communicate early. Communicate after you've solved the issue to look like a go-getter, avoid prolonged discussions and prevent people from taking credit. If you manage to take credit for someone else's hard work (say, if they're not a good communicator), all the better. That will help with maintaining a low work/politics ratio.
