The practical starting point
A site may become harder to use after a seemingly small update: an image loses its description, a table gains ambiguous columns or a new menu obscures keyboard focus. Maintenance needs a short review routine as well as an initial launch checklist.
A workable next step
Assign responsibility for checking changes that affect structure or interaction. Keep a few representative tasks and note which one a change touches. Schedule review around actual updates rather than an empty calendar ritual. W3C planning material provides context for organising this work; your plan still needs named people, realistic time and evidence from the implemented site.
Keep in your notes
- Assign responsibility.
- Keep representative tasks.
- Review changes that affect interaction.
