Heuristic Evaluation - A System Checklist

 1. Visibility of System Status

The system should always keep user informed about what is going on, through appropriate feedback within reasonable time.

2. Match Between System and the Real World

The system should speak the user’s 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.

2.21

Does the system automatically enter commas in numeric values greater than 9999?

O O O

 

2.22

Do GUI menus offer activation: that is, make obvious how to say "now do it"?

3. User Control and Freedom

Users should be free to select and sequence tasks (when appropriate), rather than having the system do this for them. 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. Users should make their own decisions (with clear information) regarding the costs of exiting current work. The system should support undo and redo.
