The UX frameworks behind every TYPENORM evaluation
A browsable, citable library of the literature we evaluate against — Nielsen's usability heuristics, the Laws of UX, and the UX Snapshot rubric. The rubric is the transparent basis for the UX Index methodology: both are derived from the same calibrated scoring model.
Nielsen's 10 Usability Heuristics
Jakob Nielsen's ten general principles for interaction design — the heuristic-evaluation checklist behind the UX Snapshot's usability lens.
Laws of UX
Named, citable heuristics drawn from psychology — Jakob's, Hick's, Fitts's and more — that explain why interfaces feel effortless or frustrating.
The UX Snapshot Rubric
The exact lenses, weights, grade bands, and severity scale that score every UX Snapshot — the transparent, calibrated basis for the TYPENORM UX Index.
