Identify system bottlenecks by running removal tests…
Identify system bottlenecks by running removal tests that ask which single node or connection failures would make specific functions impossible rather than merely slower.
Why This Is a Principle
Derives from The behavior of a system arises from its structure… (system behavior arises from structure) and A production system produces results; roughly 94%… (production problems are system problems). The principle prescribes a diagnostic method (removal tests) that follows from understanding that bottlenecks are structural features. It's actionable and general across multiple system types.
