To apply one of my favourite phrases to your post;

"What ineffable twaddle" !

I highly recommend to you the works of David Parnas, Barry Boehm, Fred Brooks, Gerald Weinberg for edification.

Start with the paper; "A Rational Design Process: How and Why to Fake It."

Big fan of all of those already. Fred Brooks in particular is seriously underrated.
