Case Study about Investigation of Applying the Delphi Method to a New Card Sorting Technique
Abstract: Open card sorting is a quantitative predesign method which is used by information architects to gather information from users to aid in the design of an information architecture. There are a number of drawbacks to the method, some severe enough to compromise the quality and validity of the results. A modified approach to open card sorting called Modified Delphi Card Sorting is proposed, modeled after a forecasting technique called the Delphi method which has been used in business, military and technology knowledge gathering. Instead of independent participant results which must then be analyzed as a whole, the proposed method conducts the study centered around a single result structure which can be more easily analyzed.
Introduction: Card sorting is a participatory usercentered design activity which information architects use to gain insights how users of their designs organize and navigate information. Participants of a card sorting study are given a set of cards which contain a piece of information on each individual card. The participant then sorts the cards in to piles and labels them. This method is used to draw out underlying mental models of information and provide an artifact of those models which can be used by the information architect to find patterns for aiding in creating or validating a design.
