The field of [[information architecture]] is founded on the study of the structure of information. If an accepted and standardized [[Taxonomy (general)|taxonomy]] exists for a subject, it would be natural to apply that taxonomy to organize both the information in the environment, and any navigation to particular subjects or functions.{{Citation needed|date=April 2017}} Card sorting is useful when:
* The variety of items to organize is so great that no existing taxonomy is accepted as organizing the items.
* Similarities among the items make them difficult to divide clearly into categories.
* Members of the audience that uses the environment differ significantly in how they view the similarities among items and the appropriate groupings of items.{{Citation needed|date=April 2017}}
==Basic method==

To perform a card sort:
# A person representative of the audience receives a set of index cards with terms written on them.

===Reverse card sorting===
In a '''reverse card sort''' (more popularly called [[tree testing]]), an existing structure of categories and sub-categories is tested. Users are given tasks and are asked to complete them navigating a collection of cards. Each card contains the names of subcategories related to a category, and the user should find the card most relevant to the given task starting from the main card with the top-level categories. This ensures that the structure is evaluated in isolation, nullifying the effects of navigational aids, visual design, and other factors. Reverse card sorting is '''evaluative'''—it judges whether a predetermined hierarchy provides a good way to find information.
===Modified-Delphi card sorting===
Created by [[Celeste Paul]], The Modified-Delphi card sort is based on the [[Delphi method]]. Rather than each participant creating their own card sort, only the first participant does a full card sort of organizing and arranging items. The next participant iterates on the first participant's model, then the third participant iterates on the second's model, and so on. The idea is that with each iteration the card sort gets more refined with fewer participants and consensus is built sooner. <ref>{{cite journal |last1=Paul |first1=Celeste Lyn |title=A modified Delphi approach to a new card sorting methodology |journal=Journal of Usability Studies |date=November 2008 |volume=4 |issue=1 |pages=7–30 |url=https://dl.acm.org/doi/10.5555/2835577.2835579}}</ref>
==Analysis==
Various methods can be used to analyze the data. The purpose of the analysis is to extract patterns from the population of test subjects, so that a common set of categories and relationships emerges. This common set is then incorporated into the design of the environment, either for navigation or for other purposes. Card sorting is also evaluated through [[dendrogram]]s. There is some indication that different evaluation methods for card sorting provide different results.<ref>{{cite

Card sorting is an established technique with an emerging literature.<ref>{{cite book |last=Spencer |first=Donna |date=2009 |title=Card Sorting: Designing Usable Categories |url=http://www.rosenfeldmedia.com/books/card-sorting/ |publisher=Rosenfeld Media |___location=Brooklyn, NY |isbn=
==Online (remote) card sorting==
A number of web-based tools are available to perform card sorting. The perceived advantage of web-based card sorting is that it reaches a larger group of participants at a lower cost. The software can also help analyze the sort results. A perceived disadvantage of a remote card sort is the lack of personal interaction between card sort participants and the card sort administrator, which may produce valuable insights.<ref>{{cite web|last1=Tullis|first1=Tom|title=Card-sorting Tools|url=http://measuringuserexperience.com/cardsorting/index.htm|website=Measuring User Experience|page=1|accessdate=29 August 2017|date=3 March 2015}}</ref>
