This doesn't strike me as being haphazard.   It's just a strategy -
how well it's implemented depends on who's doing it.

The strategy of trying to come out with a complete, best solution as a
first step doesn't seem to me to represent a better methodology.
Indeed, it's a methodology that's fraught with danger - if conceptual
mistakes are made, there's no incremental path to implementation, so
all the work that preceded the discovery of the mistake is likely to
need to be redone.
