Before you start: gather the right information
Write down the current environment, version numbers or business requirements. For a live website, create a known-good backup and make potentially disruptive changes on staging first. For business documents, confirm the client, scope and acceptance criteria before using a sample.

How to verify the result
Check the output from the perspective of the person who will use it. Test the critical workflow, note what was changed and preserve enough evidence to reverse a failed update. For public-facing sites, repeat the check while logged out and on a mobile browser. For templates, verify totals, wording and payment or ownership terms before sharing.
Common mistakes to avoid
- Do not teach that every page must use identical breakpoints.
- Avoid saying Bootstrap is required for responsive design.
