E47: Oops! The Winston W. Royce Story

E47: Oops! The Winston W. Royce Story

Author: Brian Marick March 14, 2025 Duration: 26:45

In 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.

Brian Marick hosts Oddly Influenced, a podcast that digs into the unusual and often overlooked connections between software development and the wider world. Each episode starts with a concept, theory, or practice that originated far from the realm of code-perhaps in sociology, theater, history, or urban planning-and traces its journey into the hands of software practitioners. The focus is on the concrete application: how these borrowed ideas were adapted, what problems they aimed to solve, and what actually happened when people tried them. You’ll hear about the successes, the surprising failures, and the messy, fascinating reality of translating an abstract principle into working practice. This isn’t about generic inspiration or vague parallels; it’s a detailed look at cross-disciplinary pollination, examining the mechanics of how influence actually works. The conversations are grounded and specific, avoiding hype to explore what we can genuinely learn from fields that don’t think in loops and logic. For anyone in technology or education curious about how innovation often comes from the edges, this podcast provides a unique and thoughtful perspective. It’s for listeners who enjoy deep dives into the history and sociology of their craft, who appreciate hearing stories that aren’t the usual case studies, and who are open to having their own thinking oddly influenced by the end of an episode.
