most of the discussion I've seen of documentation development assumes a
waterfall model for both the product and the documentation.

At some (many?) companies, the process is documented using the waterfall
model but practiced using a spiral model. Each model has strengths and
deficiencies so there is a natural inclination to oscillate between them.
(I'm borrowing the oscillation concept from _The Path of Least Resistance
for Managers_.)
The waterfall model depends on those frozen specs. The spiral model at least
makes a token effort to revise the specs as the changes are made downstream.

Then, there is the white-water model where you just navigate the changes as
they are made and don't bother about looking back, there's no time.
