Should we limit the interactivity?

Example: Task = average values across highlighted areas Task input: setHighlightArea > might be a list of area Task output: a number can be a graphical user interface where participants select based on predefined values another can be Task = highest values across highlighted areas Task input: setHighlightedArea Task output: getHighlightedArea > geometry

The task shouldn't have anything to do with MCDA
