Sandy wishes to log into the system. After she enters her name and password into the Login Interface, she is presented with the Main Menu. Suppose Sandy wishes to place an order for 40 kilograms of banannas - she clicks on the Orders button on the Main Menu and is taken to the Orders interface.
If Sandy were to press the Security button (because she's curious as to which employees have access to the different modules of the system), but according to her Security level profile, she should not be permitted access to the Security Interface - her pressing the greyed out Security button will have no effect - no action is taken, and Sandy is left at the Main Menu until she makes a valid choice (ie a choice to which she has access to according to her Security level).
