Accessibility and usability
Try the important service without a mouse before judging the redesign
A focused keyboard walkthrough can reveal barriers that a screenshot cannot show.
A redesigned page looks clearer, but a visitor using a keyboard cannot reach the final action. Visual review and a useful service walkthrough answer different questions. Include both when agreeing how an important journey will be checked.
Choose a complete task
For a fictional Estonian organisation, use a service enquiry from reading the offer to receiving the correct acknowledgment. Follow links, choose any options, enter demonstration details and recover from a deliberate error. Observe where focus goes and whether the current action is clear.
Do not limit the exercise to the homepage. A third-party booking step, document viewer or confirmation screen may be part of the actual service a customer needs to complete.
Record an observable barrier
Describe what the person tried to do, what happened and what prevented progress. “The final button cannot be reached by keyboard” is more actionable than a broad label saying the page feels inaccessible.
TTJA's official accessibility guidance addresses service requirements and applicable scope. A limited walkthrough is useful improvement evidence, but it does not establish complete conformance or decide the legal duties of a particular organisation.
Retest the change in context
After a correction, repeat the original task and the nearby error case. Check that the improvement did not move the difficulty elsewhere. Agree when specialist assessment and participation by people with relevant access needs belong in the project.
An accessibility improvement engagement can begin with this focused evidence. A screenshot, an automated score and a successful keyboard task should be reported for what each actually demonstrates.
