Before measuring screens or pages, establish the outcome, priority journeys, operating constraints and evidence already available.
Customer and product priorities
Current technical and delivery constraints
Evidence already available
2. Follow the real journey
Review whether a first-time user can understand the offer or task, make the required decisions, recover from problems and reach the intended outcome on relevant screen sizes.
3. Check the foundations
Depending on scope, inspect product behaviour, content, responsive presentation, accessibility observations, integration boundaries, crawl access, metadata and search evidence supplied by the customer.
4. Separate findings from recommendations
A finding records what can be observed. A recommendation explains a proportionate response. Priority depends on customer impact, confidence, effort, risk and dependencies.
5. Verify important changes
Material fixes should be rechecked through the real journey and against the evidence that justified them. Completion means confirming the intended behaviour, not only changing code or copy.
