3.3.6: Error Prevention (All)

What it means

At AAA, users must be able to review and confirm before any submission, or reverse submissions afterward. This extends error prevention to all forms, not only legal or financial ones.

Even low-risk forms get a confirmation path.

How to fix it

• Show a summary screen before every significant form submission.
• Offer edit links on the confirmation view.
• Allow users to cancel or undo soon after submit when technically possible.
• Log submissions so support can help recover from mistakes.

Quick examples

• Good: A job application review page lists all answers with Edit links before Send.
• Bad: Survey submits on the last question with no chance to review answers.
• Good: Users can recall a sent message within 30 seconds.
• Bad: Profile changes save field-by-field with no summary or undo.
