I loved when I found this on Wikipedia on the Waterfall Process for Software Development:
The first formal description of the waterfall model is often cited as a 1970 article by Winston W. Royce, though Royce did not use the term “waterfall” in this article. Royce presented this model as an example of a flawed, non-working model (Royce 1970). This, in fact, is how the term is generally used in writing about software development—to describe a critical view of a commonly used software practice.
Yes, the canonical reference to waterfall, the thing that coined that phrase, was “don’t do this, it doesn’t work”. And yet, for 30 years this dominated the software development industry.
