openSUSE:YaST styleguide whyconsistency

Why should I care about consistency?

Consistency supports the user in performing tasks in a efficient, effective and satisfying way. It will

• Help user to navigate through different YaST modules following the same procedures.
• Allow user to focus on the task not the tool.

Consistency increases:

• suitability for the task: Does the software support users in performing their tasks?
• self-descriptiveness: Is the software self-explaining and understandable?
• controllability: Can a user influence how to work with the software?
• conformity with user expectations: Does the software fit user's expectations and habits by using a consistent and coherent design?
• error tolerance: How easily can a user recover from errors?
• suitability for individualization: Can users adapt the software to their personal needs without too much effort?
• suitability for learning: Does the design of the software provide an easy way of learning new functions?
