Open your store, choose one important customer journey and apply each section to the decisions your team is making now.
Frame the decision
Design for the smaller decision surface first: essential information, comfortable targets, predictable controls and fast feedback. Then enhance the layout when more room is available.
What to inspect
Test sticky actions, filters, media galleries, variants, keyboards and error states on real devices. These interactions expose issues that static screen reviews miss.
Evidence worth keeping
Analytics checks, annotated screens, customer questions, technical profiles and a prioritised decision log make recommendations easier to act on.
Turn the finding into action
Keep content honest about available space. A shorter, clearer hierarchy usually performs better than hiding a desktop volume of copy inside accordions.
Make the recommendation useful: assign an owner, a success signal and a review date.
