Card Sorting
Card sorting asks participants to group and label items the way they expect, helping teams design an information architecture that matches users' mental models.
Card sorting is a method for designing structure. Participants sort a set of items into groups that make sense to them, and optionally name those groups. The patterns across many participants reveal how users expect content to be organised.
In an open sort, participants create and name their own groups. In a closed sort, they place items into categories you provide. Open sorts help you discover structure; closed sorts help you validate one.
It is an early-stage, generative method. It shapes the architecture before you test whether people can navigate it with tree testing, or use the finished interface with usability testing.
OpenScouter focuses on behavioural usability testing of real flows. Card sorting and tree testing are best run in dedicated information-architecture tools, then validated with behavioural sessions once the design is built.
