Wow. This one really caught my eye. Fred Brooks of Mythical Man-Month fame, whose wisdom on software is still applicable decades later, wrote an article in 1987 that damn near predicted the Agile movement. This isn't Agile in the name-brand TDD sense, but a more general recognition that the most effective way to develop complex software is to iteratively "grow" it. Build one to throw away becomes a "spike". I can definitely see the evolution of the ideas a bit more clearly now.

It's worth reading this one, as quoted by Indefinite Articles, quoted originally by Jeff Sutherland. Observe also that he's quoting even older work for the concept. This is 1987! Why the heck did Waterfall survive so long?
