I interned in the software process group for a defense company building sattelites. It had the other extreme of the process spectrum- true waterfall/CMMI processes in place, but they were so painful that people just did work and then figured out how to claim they followed the process afterwards. They actually had a couple good processes that I walked away with (different levels of formality for code reviews, structured and a risk based QA processes), but overall it was about frustration and a molasses like movement. I was glad to end up on consumer software for a while after college.
