Poka-yoke: a structural design intervention that makes errors detectable or impossible through environmental changes rather than relying on human memory, vigilance, or self-regulation
Why This Is a Definition
This definition establishes the genus (structural design intervention) and differentia (makes errors detectable or impossible through environmental changes). It specifically distinguishes poka-yoke from human-based error prevention methods like memory or vigilance. The definition captures the core principle that poka-yoke works through structure rather than human behavior, which is central to the lesson's example of the spring-counting dish. It's precise enough to distinguish this concept from general design principles or error prevention methods.
