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?

It has been said,


While testing can establish with certainty that
a piece of software has bugs, no amount of testing
can ensure that it has no bugs.

This statement is slightly too strong; there are a few
cases where there is a finite and small number of inputs
and one can "test" the program by running it on all
possible cases. For an example, consider a tic-tac-toe
program.

Most real-world programs do not deal with such a simple
situation.
