## CRC Cards

- In the CRC card method, you create an index card for each class.
- CRC stands for "classes", "responsibilities", "collaborators."
- As you think about the verbs in the task description, pick the card of the class that you think should be responsible, and write that responsibility on the left-hand side of the card.
- For each responsibility, you record on the right-hand side of the card which other classes (the collaborators) are needed to fulfill it.
