Characteristics of Good Design
From The Design of Everyday Things by Don Norman
Discoverability
Can users figure out what actions they can take, along with where and how they can complete these actions?
Signifiers
Signifiers indicate how to correctly use or interact with something.
Example: The type of handle on a door (such as a plate on a door indicating that you have to push to open it).
Constraints
Constraints limit the actions users can take.
Example: Graying out unavailable actions on a menu (such as graying out the Undo and Redo options on a menu when you haven’t taken any actions yet in a document).
Mappings
How obvious is the relationship between an object and its controls?
Example: Stove burners and their dials (such as displaying the dials for four burners in the same orientation that the burners are laid out. So, the upper-left dial controls the upper-left burner, the upper-right dial controls the upper-right burner, and so on).
Feedback
Feedback lets users know that the system is processing a request or action.
Example: Confirmation messages (such as showing a success message after a user successfully submits a form).
Understanding
Is it easy to understand what the application as a whole means?
Is it easy to understand what the individual controls, settings, etc. mean?
How should the application be used?
