A complex system cannot be "made" to work. It either works or it does not. A simple system, designed from scratch, sometimes works. Some complex systems actually work. A complex system that works is invariably found to have evolved from a simple system that works. A complex system designed from scratch never works and cannot be patched up to make it work. One has to start over, beginning with a working simple system. https://en.wikipedia.org/wiki/Systemantics
