The underlying assumption with requirements is often not stated explicitly: that people _can know_ everything in detail, in advance.

If that is the case, surely we can find better ways to uncover the requirements, and better tooling will help solve the problem.

Experience tells me that people don’t know everything beforehand. Thus the key assumption is not valid.

Then the question we should be asking is: how do we most efficiently bring people to where they discover and understand the requirements?

Experience tells me people are much better at giving concrete, specific feedback to a running system than to an abstract requirements document.

Hence iterative development.

In essence requirements are not a document by a process.
