Reviewing the CRC Model
1.  All participants in the review (of the CRC model) are given a
subset of the CRC model index cards.
2.  All use-case scenarios (and corresponding use-case
diagrams) should be organized into categories.
3.  The review leader reads the use-case deliberately. As the
review leader comes to a named object, she passes the token
to the person holding the corresponding class index card.
4.  When the token is passed, the holder of the class card is
asked to describe the responsibilities noted on the card. The
group determines whether one (or more) of the responsibilities
satisfies the use-case requirement.
5.  If the responsibilities and collaborations noted on the index
cards cannot accommodate the use-case, modifications are
made to the cards.
