When you need to figure out why users keep getting stuck on a specific flow, this walks you through a task step by step from a novice user's perspective. It asks four questions at each action: will they know what to do, can they find the control, does it look like it does what they need, and will they get feedback. You break down something like "create account and add to wishlist" into atomic steps, then systematically identify where confusion happens. The output is concrete, with severity ratings and a predicted success rate for first-time users. It's more surgical than running general heuristics, best when you're debugging a critical journey like checkout or onboarding and need to know exactly where people will bail.
