Amélie Boucher's 12 Ergonomic Criteria are rooted in the French HCI tradition, codifying what ergonomics research has found about how people actually interact with software. Where Anglo-American heuristics tend to be high-level rules of thumb, Boucher's criteria are closer to ergonomic measurements: workload, adaptability, error management, compatibility between user mental models and the system.
Each criterion maps to concrete interface symptoms a reviewer can check for. The "workload" family, for example, splits into brevity, information density, and grouping — each one a separate lens to hold over a screen. That granularity makes Boucher's criteria especially useful for teams that want evaluations to produce reproducible, specific findings rather than subjective judgements.
Reach for Boucher when you're evaluating a complex professional tool, a data-entry product, or any interface where cognitive load is the main concern. They pair well with Nielsen's heuristics for general UX and ISO 9241 for a more formal review.
