Card sorting

Card sorting is a technique that helps uncover how people organise information by having participants sort cards featuring words or phrases into groups. Card sorting informs the design process by showing how participants relate and categorise concepts, which can help create visual and structural relationships that make sense to users . These relationships are then “used to understand the sequence of tasks in an activity, structure databases, organize navigational elements, or name features and interface elements”  . Goodman et al.  describe the different types of card sorting and explain when and how to use them in design research.
