• Users should not have to wonder whether different words, situations, or actions mean the same thing.
• Follow platform conventions.

Question 8

Error prevention

Answer 8

Even better than good error messages is a careful design which prevents a problem from occurring in the first place.

Question 9

Recognition rather than recall

Answer 9

• Make objects, actions, and options visible.
• User should not have to remember information from one part of the dialogue to another.
• Instructions for use of the system should be visible or easily retrievable whenever appropriate.

Question 10

Flexibility and efficiency of use

Answer 10

• Accelerators – unseen by the novice user – may often speed up the interaction for the expert user so that the system can cater to both inexperienced and experienced users.
• Allow users to tailor frequent actions.

Question 11

Aesthetic and minimalist design

Answer 11

• Dialogues should not contain information which is irrelevant or rarely needed.
• Every extra unit of information in a dialogue competes with the relevant units of information and diminishes their relative visibility.

Question 12

Help users recognize, diagnose, and recover from errors

Answer 12

• Expressed in plain language (no codes)
• Precisely indicate the problem
• Constructively suggest a solution.

Question 13

Help and documentation

Answer 13

• Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation.
• Help information should be easy to search, focused on the user’s task, list concrete steps to be carried out, and not be too large.
