Using cognitive walkthroughs to review designs
summary
Cognitive walkthroughs test real task flows using concrete personas, not vague guidelines: a keyboard-only review finds 90 tabs to reach checkout on a supermarket site, prompting added skip links to trolley and login. Process: pick an accessibility persona (example persona Joe with hand tremors), list tasks and step-by-step actions, perform the walkthrough with keyboard, screen reader or a paper magnifier window, log failures against five user-focused questions, then fix design or retrofit before spending time on full user testing.
