@BrianGoetz @richcampbell @CompSciFact I remember my first college placement to build a system for a small QUANGO. I learned then that not everyone can articulate their requirements in a way that would allow a decent spec to be written. I take the enthusiasm for Agile methodologies to be confirmation
@CompSciFact This happened: "Is there a requirements document for the project?" "Yes. It's in a safe. Developers can't see it. " "Er... why?" "We don't want it leaked to our competitor."
