Let people check before they commit

How to do it

Show a review step with every entered value and an edit link before the final submit. Or ask for confirmation, or offer undo for a stated time. Do this for every payment, contract, test answer and account deletion. See also let people undo or confirm destructive actions.

Example

<h2>Check your order</h2>
<dl>
  <dt>Delivery address</dt><dd>12 High Street <a href="/checkout/address">Change</a></dd>
  <dt>Total</dt><dd>€48.00</dd>
</dl>
<button type="submit">Place order</button>

How to check

A browser test runs each such flow. Before the final action it finds a review step, a confirmation or an undo control.
