6. Permit easy reversal of actions

rule

 

                   As much as possible, actions should be reversible. This feature relieves anxiety, since the user knows that errors can be undone, and encourages exploration of unfamiliar options. The units of reversibility may be a single action, a data-entry task, or a complete group of actions, such as entry of a name-address block. Example of a software that use the 6th rule of shneiderman’s 8 golden rule of interface design is MICROSOFT WORD because it has provided an “undo” and “redo” button that gives the user an easy way to reverse any actions not important to them.
