Price-to-Part Theory
A framework for building resilient manufacturing systems.
The Core Principle
Part Count
Drives complexity
Complexity
Drives fragility
Fragility
Drives cost and burden
Every additional part in a system introduces potential failure points, maintenance requirements, and cognitive overhead.
Reducing Unnecessary Complexity
Lowers operational risk
Strengthens resilience
Protects workers
Enhances security
This is both a technical and moral imperative.
Applications
-
Bill of Materials (BOM) Analysis
Question every component. Can two parts become one? Can a sub-assembly be eliminated?
-
Supply Chain Simplification
Fewer unique parts means fewer suppliers, less coordination overhead, and reduced supply chain risk.
-
Software Architecture
The principle extends to code: fewer dependencies, simpler interfaces, reduced cognitive load for maintainers.
-
Critical Infrastructure
Systems that societies depend on must be simple enough to understand, maintain, and secure.
"Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away."Antoine de Saint-Exupery
