- CRC cards are very useful indeed in the early stages of design when one
- is identifying objects, their responsibilities and their relationships
- with other objects (how's that for obfuscating everything which is
- implied in their name?).
-
- An implementation in Smalltalk? Hmm. A good student project perhaps
- but in practical terms a 5" by 3" card box, a supply of cards, a pencil
- and a rubber (eraser for North American readers) are all that is
- required to make use of this technique. Advanced practitioners also
- make use of black or white boards together with the appropriate chalk or
- pens.
-
- There was a good article about using CRC cards in "The C++ Report"
- Volume 3 Number 8 (September 1991).
