It’s no secret that we’re keen on building websites that are easy to use here at Brookside Studios. Ensuring proper thought is put into user experience (UX) design is a top priority for us and our web design processes reflect this effort. However, we’re not the first ones to put a fair amount of consideration into website usability. In fact, way back in 1990 Jakob Nielsen, a pioneer in UX design and founder of The Nielsen Norman Group, co-wrote the 10 Usability Heuristics for User Interface Design. In this short composition, Nielsen lays out what can only be taken as the 10 commandments for website usability.
Below you can find all 10 commandments in their entirety. For more explanation on Nielson’s writings, check out this SlideShare he put together with specific examples.
Visibility of system status
The system should always keep users informed about what is going on, through appropriate feedback within reasonable time.
Match between system and the real world
The system should speak the users' language, with words, phrases and concepts familiar to the user, rather than system-oriented terms. Follow real-world conventions, making information appear in a natural and logical order.
User control and freedom
Users often choose system functions by mistake and will need a clearly marked "emergency exit" to leave the unwanted state without having to go through an extended dialogue. Support undo and redo.
Consistency and standards
Users should not have to wonder whether different words, situations, or actions mean the same thing. Follow platform conventions.
Even better than good error messages is a careful design which prevents a problem from occurring in the first place. Either eliminate error-prone conditions or check for them and present users with a confirmation option before they commit to the action.
