In a way it was awful. It was sort of like anti-agile. There was absolutely no dialog between the devs and the customer. If the requirements said the throttle had to be on the touchscreen (to use an example from another comment), that's what we did, even if we strongly suspected this was a really bad idea. I was too far down the food chain to know where these requirements came from, it was like they were handed down to Moses on stone tablets. How fast could we develop? In addition to the requirements, we were also handed a schedule (a PERT chart, if anyone still knows what that is). It was laughably padded. Padded so much that it would have been impossible to fall behind schedule. I almost always finished my work for the day before lunch. Sometimes I would then go for a three martini lunch with the sales guys, or spend the afternoon in the library or flying the F-14 simulator. Sometimes I would spend the afternoon working on tools to make debugging easier. It was a fun job, but ultimately unsatisfying and I left after two years.
