What are CRC cards in agile?
Definition. CRC cards (for Class, Responsibilities, Collaborators) are an activity bridging the worlds of role-playing games and object-oriented design.
Why do we design CRC cards in XP model?
Although CRC cards were originally introduced as a technique for teaching object-oriented concepts, they have also been successfully used as a full-fledged modeling technique. My experience is that CRC models are an incredibly effective tool for conceptual modeling as well as for detailed design.
