Re: [extremeprogramming] The principle behind How Test-Driven Development Works

If your audience gets OO programming, a few good TDD session makes dynamic
KISS compelling, especially on whatever they are currently working on

If your audience does not get OO programming, all the compelling
mathematical arguments in the world won't stick after they leave the room
(or put down the article).  In practice, they will still fall back to
planning the whole thing out the first time they find themselves doing any
rework.

I love a good mathematical explanation (having a math degree and having
many times taught all the math courses in the CS curriculum), but the math
literally argues for top-down pre-design when I know in my heart that
effective software development is dynamic because it is about human
interaction, not the math.
