Task appropriateness
In usability research, the appropriateness of a task is a criterion that describes whether the functions of a system (e.g. machine, software or website) serve to achieve the goals that a user is pursuing with them.
definition
The DIN EN ISO 9241 -110 defined: "A dialogue is task-appropriate if it helps the user to do its task effectively and efficiently."
More generally, one can say that task appropriateness exists if the user is not distracted from the actual task goal through the use of the system, but achieves this with less or the same effort and also does it more completely or at least in the same way as before. The appropriateness of the task is distinguished from the appropriateness of the process .
Examples
That means, for example, that
- Input and output save the user unnecessary work steps (simply save and close, as well as reopening a document)
- the user is relieved by means of automated processes and presettings (automatic start procedures, presetting with standard values, positioning the mouse cursor, etc.)
- no superfluous information display or assistance is given.
