“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 simple system.” — John Gall, systems theorist
- Gall’s Law says that all complex systems that work evolved from simpler systems that worked.
- If you want to build a complex system that works, build a simpler system first, and then improve it over time.
- Gall’s Law is why Prototypes and Iteration work so well when creating value.
- Creating a complex system from scratch is sure to end in failure.
Questions for Consideration:
- Are you trying to build a complex system from scratch?
- Could you start with a simpler system that already works, then build upon it?
