General Development I've been developing software for quite a few years. One of the issues that seems to come up again and again in my work is this concept of design and implementation. I recall it being a significant part of my education at the University of Waterloo's Computer Engineering program as well. The message was always the same. Never write code first. First you must design software by writing a design document, flow charts, pseudo-code, timing charts... then it's merely a trivial matter of implementing it. Make note of the attitude here given towards implementing. The real work is in the design, and it's just a trivial matter of implementing it. It sounds so simple doesn't it? Now, how often does this work out in real life?

Goedel's Second Theorem

Member since:

Another problem is consistency of the specifications.
Goedel's Second Theorem says, informally:

A set of specifications is consistent if and only if
it admits an implementation.

I've seen lots of times the specifications were inconsistent.
