Comments on book review

If you built a house the way some of you seem to think you should build
a program, we'd be in trouble. The software sevelopment cycle is more
that just a textbook approach. It is a reality in the commercial world
of industrial-strength business software.

You gotta plan ahead. If not how do you know what you are going to
build and how will you know when you've built it?
