Traditional waterfall model doesn't allow for iteration between the main steps, and this was followed historically, and caused absolutely massive delays and cost overruns in projects through the 70s, 80, and 90s. Popping iteration onto Waterfall model and still calling it Waterfall model is being disingenuous.

But a 9-figure project I was (fortunately briefly, though not brief enough, around 1 year) on was several years late and delivered only half the features the users needed. Why? Because they made the plan in the mid-00s, and the circumstances changed but the plan didn't. They did what Waterfall describes, they committed to their initial analysis and plan and never looked back. Fortunately they learned after that, but it was a costly exercise.
