On requirements and Agile: One of the discussions I’ve frequently had with co-workers concerns invariants in the system and known requirements. Most people could probably tell you a number of requirements for a (e.g.) radio off the top of their head, but I’ve heard developers claim those requirements don’t exist until a systems engineer writes them down. Not only that, but those known requirements are often not viewed as invariants that can be modeled and reused in every radio under development. The major problems with requirements change is the lack of recognition and capture of the invariants in the system and poor separation of concerns.
