Make a product accessible before the final polish
Check labels, focus, contrast and recovery in the workflows people actually use.
Start with a complete journey
Choose a common task and test it from entry to confirmation. Accessibility problems often appear between screens, not only inside individual components. In a fictional appointment tool, a visitor must select a date, enter details, understand an error and confirm the booking. Review that sequence with keyboard navigation and enlarged text rather than checking only the opening page.
Use clear names and visible states
Give controls labels that explain the action or the information requested. Do not rely solely on a placeholder that disappears while someone types. Show which item is selected, where keyboard focus sits and whether an action is processing. Colour can reinforce a state, but text or a familiar symbol should also communicate its meaning.
Treat errors as part of the design
Place a specific error near the relevant field and explain the correction. Keep entered values when a submission fails. Move attention thoughtfully to the problem without unexpectedly jumping the page during typing. Ask people using different access methods to try the workflow; an automated scan is useful but cannot explain whether the whole task makes sense.
Make checks repeatable
Add a compact review to each release: keyboard path, focus visibility, labelled controls, readable contrast, enlarged text and understandable errors. Record observed problems with reproduction steps instead of vague comments about usability. Your next action is to complete one primary task without a mouse and note every place where focus, meaning or recovery becomes unclear.
