Record how they discover the service, what they need before starting and how they know the task has finished. Mark every hand-off where the person must repeat information.'},
{title:'Write a clear action label',kind:'Writing guide',time:'10 minutes',summary:'Name what will happen after a button is activated.',body:'Use a verb and the object of the action. Compare Save draft with Send application and make the distinction explicit. Keep destructive and reversible actions visually and verbally distinguishable.'},
{title:'Review keyboard access',kind:'Checklist',time:'20 minutes',summary:'Inspect focus order, visible focus and recovery.',body:'Work through the page using only the keyboard. Check the first useful control, the order through repeated items, the next-page action and return from a detail view. A selected page and keyboard focus are separate states.'},
{title:'Prepare an error message',kind:'Writing guide',time:'15 minutes',summary:'Explain the issue next to a recoverable action.',body:'State what needs changing and how to change it. Preserve the person’s input. Avoid a generic failure message when the application knows which field or prerequisite is causing the problem.'},
{title:'Test a narrow layout',kind:'Checklist',time:'20 minutes',summary:'Keep reading and actions available on a small screen.',body:'Inspect a long title, two lines of metadata and the pagination controls at a narrow width. Avoid hiding essential actions behind hover. Check that only a genuinely two-dimensional region scrolls sideways.'},
{title:'Record the decision',kind:'Template',time:'10 minutes',summary:'Give the next team enough context to continue.',body:'Record the decision, the evidence used, the person responsible and the condition that would make the team revisit it. A useful record explains the reasoning without presenting an experiment as a settled rule.'}
