It needs to be part of all of them, but you can't do it meaningfully in any one of those steps, because you don't have a working product to actually show the customer until the end.

As-if! '… we need to accept the possibility that we will iterate during the development, perhaps within a given phase (eg reworking a design until it seems that it will give the required performance), or from one phase back to another (eg to correct a faulty design decision that, during construction, is exposed by a failure to be able to implement it). The biggest iteration is the one where we complete the development and, when we see what we have produced, we decide we need to start again and redefine the user requirements in the light of what we have produced. Such iterations happen in the real world and we wanted to accept this fact and put it in our model. Royce first formulated this idea in what he labelled the waterfall model … page 31 'The "oldest" process model is the waterfall model … This shows a similar progression from inception, through definition, the various stages of design, code, unit testing and integration to final acceptance. The fact that that progression is never smooth and monotonic is acknowledged by drawing little backward arrows suggesting iteration." page 39 1990 Strategies for Software Engineering: The Management of Risk and Quality https://www.google.com/books/edition/Strategies_for_Software_Engineering/Wd8mAAAAMAAJ?hl=en&gbpv=1&bsq=waterfall https://www.google.com/books/edition/Strategies_for_Software...

  ...what? Nothing here talks about getting customer feedback on a finished product rapidly.

    Be real.

      I assure you I'm entirely "real". What's not real is the notion that waterfall didn't ever exist. It did. That's objective fact. It was prevalent across the industry, that's also objective fact.

        As before, "… we will iterate during the development … Royce first formulated this idea in what he labelled the waterfall model …" page 31. Seems like you deny that waterfall model.
