The Evolution of Complex Systems 20 Sep 2012
An excerpt from Object Oriented Analysis and Design quoting J. Gall’s 1986 work: How Systems Really Work and How They Fail:

A complex system that works is invariably found to have evolved from a simple system that worked…. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over, beginning with a working simple system.

The last 6 words of this excerpt say it all – begin with a working simple system.
