Review Page That Isn’t Actually Editable Before Final Submission

3.3.4 — Error Prevention (Legal, Financial, Data)

Scenario

Setting

A professional networking site's profile editor

What’s wrong

Review page exists but is not actually editable (can't correct before final submit. "reversible/checked/confirmed" all absent).

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

Reach the review page in a submission flow and try to edit an entry: if the fields aren't actually editable, it fails the 'correct before submit' requirement.

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 professional networking site's profile editor, this barrier is gone for everyone in legal, financial, or data-changing flows — they no longer have to work around this.
