CONSISTENCY THE INTERFACE DESIGN IS IN HARMONY AND THE SAME APPLIES TO ALL SCREEN IN A SOFTWARE. Every user interface uses the same words or commands perform the same functions.

CLARITY CLEARNESS OF LABELS ON ALL ICONS TO MAKE THE SYSTEM EASY TO UNDERSTAND Developer should use relevant icons or graphics to indicate the information. Icons, word or commands should be clearly labeled so that users can understand them easily.

NAVIGATION USERS CAN MOVE AROUND THE MENUS, HELP FILES OR OTHER SCREENS IN A SYSTEM. It should be clear on how to exit or proceed from screen to screen in a program
