Error Prevention (UX)

Good interfaces try to prevent mistakes before they happen rather than only reporting errors afterward. Error prevention in UX can involve understandable labels, sensible field constraints, clear explanations of required information, and a chance to review a consequential choice. A handyman booking form might confirm the selected service date and address before a request is submitted. People should be able to correct problems without starting over. The right safeguards depend on the consequence of a mistake; a minor typo and an irreversible payment are not equivalent. Error prevention differs from form validation, which checks entered information against rules, although validation can support a wider prevention strategy.
