Apply the principle of the Weakest Link — a system''s reliability is determined by its least reliable component, not by the average. Use when designing critical-path workflows, evaluating dependencies for risk, deciding where to invest in robustness, auditing onboarding or checkout flows for the step most likely to fail. The user''s experience of the product is dominated by its worst step. Improving the average without improving the weakest step often doesn''t improve the experience at all.

From the source SKILL.md

The metaphor comes from physical engineering, but the principle applies broadly. In a workflow, the user's experience is dominated by the worst step they encounter. In a system of dependencies, total uptime is bounded by the least reliable dependency. In a feature set, the perceived quality is dragged down by the most-broken feature. Average quality is the wrong metric; weakest-link quality is closer to what users actually experience.
