Heuristic Evaluation - Weinschenk and Barker Classification

Weinschenk and Barker Classification

Susan Weinschenk and Dean Barker created a categorization of heuristics and guidelines by several major providers into the following twenty types:

1. User Control: heuristics that check whether the user has enough control of the interface.

2. Human Limitations: the design takes into account human limitations, cognitive and sensorial, to avoid overloading them.

3. Modal Integrity: the interface uses the most suitable modality for each task: auditory, visual, or motor/kinesthetic.

4. Accommodation: the design is adequate to fulfill the needs and behaviour of each targeted user group.

5. Linguistic Clarity: the language used to communicate is efficient and adequate to the audience.

6. Aesthetic Integrity: the design is visually attractive and tailored to appeal to the target population.

7. Simplicity: the design will not use unnecessary complexity.

8. Predictability: users will be able to form a mental model of how the system will behave in response to actions.

9. Interpretation: there are codified rules that try to guess the user intentions and anticipate the actions needed.

10. Accuracy: There are no errors, i.e. the result of user actions correspond to their goals.

11. Technical Clarity: the concepts represented in the interface have the highest possible correspondence to the domain they are modeling.

12. Flexibility: the design can be adjusted to the needs and behaviour of each particular user.

13. Fulfillment: the user experience is adequate.

14. Cultural Propriety: user's cultural and social expectations are met.

15. Suitable Tempo: the pace at which users works with the system is adequate.

16. Consistency: different parts of the system have the same style, so that there are no different ways to represent the same information or behavior.

17. User Support: the design will support learning and provide the required assistance to usage.

18. Precision: the steps and results of a task will be what the user wants.

19. Forgiveness: the user will be able to recover to an adequate state after an error.

20.Responsiveness: the interface provides enough feedback information about the system status and the task completion.

    She is a procession no one can follow after
    But be like a little dog following a brass band.
