Gall’s law, or: Release early, release often

I didn’t know a pediatrician, John Gall, had stated an early version of the iterative paradigm:

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.
— John Gall, “Systemantics: How Systems Really Work and How They Fail”

I believe this is a variant of the release early, release often software development philosophy that has been proven to work in many cases. Gall didn’t limit his statement to software.
