3.3.4 — Error Prevention (Legal, Financial, Data)
Scenario
Setting
A subscription box service's account settings
What’s wrong
Test/exam submissions locking answers instantly on selection.
Example
<button onclick="submitPayment()">Pay Now</button> <!-- no review step -->Why it matters
Everyone in legal, financial, or data-changing flows — especially people prone to input mistakes.
How to test
Submit a test/exam answer: if it locks in instantly on selection with no chance to review, it fails.
How to fix
The submission must be reversible, checked with a chance to correct, or confirmed through an editable review step.
<button onclick="showReviewStep()">Review Order</button><!-- review screen --> <button onclick="submitPayment()">Confirm Payment</button>Legal, financial, or data-deleting submissions need a chance to review, correct, or confirm before they're final.
Outcome
On a subscription box service's account settings, this barrier is gone for everyone in legal, financial, or data-changing flows — they reach the same outcome without extra effort.
Who is affected
Everyone in legal, financial, or data-changing flows — especially people prone to input mistakes.
