John Gall's book

Gall’s Law

Today, I discovered an interesting law, Gall’s law from John Gall. Le’s discover how it can be applied to programming.

John Gall in its book Systemantics: How Systems Really Work and How They Fail. states :

“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 with a working simple system.”

This quote is relevant even after 1975 its date of writing. Successful is written first as a simple system. Moreover, a simple system is probably conceived by a person that needs its system, not an engineer. We need to empower people to write their own and at a point, we can make them evolve to enterprise-grade solutions. But skipping this step and you will have software promised to be a failure.


A good reference to read more about it
