VARIATIONS ON A THEME: CARD-BASED TECHNIQUES FOR PARTICIPATORYANALYSIS AND DESIGNINTRODUCTIONIn this tutorial, participants gain hands-on experience with three related participatory methods throughwhich groups can share and co-create their visions. We presented a panel based on this idea at UPA’97,and it was very well received. One of the recommendations from the evaluations of the panel was toexpand it into a full-day tutorial. We are proposing to meet this request.The tutorial presents three card-based methods for participatory analysis and participatory design:• CARD (Collaborative Analysis of Requirements and Design)• CUTA (Collaborative Users' Task Analysis)• TOD (Task Object Design)The CARD technique was discovered by Tudor in 1992, and was subsequently refined by her andcolleagues (Tudor et al., 1993). Using physical materials similar to playing cards, CARD is a participatorytechnique through which users and software professionals (and other stakeholders) may collaborativelyanalyze an existing or proposed task flow, or may design a new task flow. The materials and the processesaround the materials support participatory work in several ways: The materials become a low-tech "common language" that supports rich communication among thestakeholders. The process of using the materials makes sure that no single participant may "own" the cards, whichthen become the "property" of the group. The simple low-tech physical form of the cards allows ...
