I just discovered the works of John Gall and I LOVE IT!

Just two quotes for now:

“A complex system that works is invariably found to have evolved from a simple system that worked. The inverse proposition also appears to be true: A complex system designed from scratch never works and cannot be made to work. You have to start over, beginning with a working simple system.”
—John Gall

and

Complex systems tend to produce complex responses (not solutions) to problems.
—John Gall

Wonderful.
