Poke-yoke is a japanease word which means “mistake-proofing” or “inadvertent error prevention”.
The Poke-yoke is the art of designing the User Experience in an efficient way that grants a good understanding of The interface to prevent User Errors and to avoid Unconscious Slips.
Example1 : Adding a ““Remove account‘’ Button next to “Edit Profile” button is very dangerous because the user may delete his account with a wrong click instead of editing his account information.
Example2 : A wrong UX design by facilitating access to an action of “sending Missile Alert” which happened in Hawaii.
By mistake and because of a bad Human interface design, a terrifying message was sent to all residents of Hawaii . They received an emergency alert that a ballistic missile is on the way.
So How can we Prevent the same UX mistakes ?
The Answer is :
1- Sort the User actions By Levels : Low,Medium,High.
2- Keep the interface simple and easy to use for daily basic actions or Low level actions.
3- Keep the administrative actions (high level): removing access, deleting accounts,unsubscribing, unfriending people” harder to access and manipulate … with popups, alerts and confirmations windows, To Push the user to think Twice before making his decision( or destroying a state ).
The more the Risk is, the more you have to aim for complexity in the UX and the Interactions. Risky Actions should be Hardly Reachable.
