Abstract:

Card sorting offers a systematic and statistically significant process for answering questions about hierarchy design. However, those of us who have run card sorts know there is an art to conducting successful card sort studies, and there are many variables that can affect the usefulness of results. In this column, I’ll discuss the challenges and limitations of card sorting and review alternative and complementary techniques that designers can leverage when developing an information hierarchy for a large-scale Web site.
