This paper presents a technique involving index cards and roleplay to assist in making use case development more accessible and better guided. The technique is based on the established CRC card technique used for object-oriented design. In our technique, essential use cases are recorded on cards, and roleplay is used for development and review. The paper presents the technique, and outlines our experience in applying it. We found the technique did achieve the expected benefits, and was especially useful in determining the system boundary. We also saw other significant benefits, some relating especially to the nature of essential use cases.
