E47: Oops! The Winston W. Royce Story
Download MP3In 1970, Winston W. Royce published a paper “Managing the Development of Large Software Systems.” Later authors cited it as the justification for what had come to be called the "waterfall process." Yet Royce had quite specifically described that process as one that is "simplistic" and "invites failure."
That's weird. People not only promoted a process Royce had said was inadequate, they cited him as their justification. And they ignored all the elaborations that he said would make the inadequate process adequate.
What's up with that? In this episode, I blame metaphor and the perverse affordances of diagrams.
I also suggest ways you might use metaphors and node-and-arrow diagrams in a way that avoids Royce's horrible fate.
In addition to the usual transcript, there's also a Wiki version.
