Card Sorting

Card Sorting — UX Knowledge Base Sketch #3

The main goal

The main goal of Card Sorting is to improve a website’s or an application’s Information Architecture, to help designing how the information is organized and labelled.

The process

The process of Card Sorting is very straight-forward: we give the participants already written cards (each contains an information type or a function). Then we ask them to group those cards. Card Sorting can be conducted in two different ways:

  • Closed Card Sorting means that we determine the main categories before the test, and the participants have to assign the cards to those predefined groups.
  • Open Card Sorting gives more freedom to the participant: they can not only group the cards, but they can create and name the categories.

Card Sorting also shows if there are any significant differences in the mental model of the user segments.
