>What we should have realized by now is that we never did waterfall right because it's inventor Winston Royce required it to be done TWICE for each project. Two iterations.

Reading the original waterfall paper was eye opening for me. I saw that we're falling into patterns that are decades old. Someone insightful tries to explain that learning and building are two sides of the same coin, and companies read it as "ok, I need a learning team and a doing team" and run with it in the wrong direction. Taking the conceptual structure of some paper of manifest and applying it cookie-cutter style is missing the point entirely.

What Conway and Royce were trying to convey is that the social process that underlies software matters. What people do with it on the field is using the examples employed in the explanation and mistaking them for the solution to their lack of respect for the intricacies of social processes.
