Applying the object-oriented paradigm to the development of software requires individuals and teams to think and act differently than when designing procedural projects. While proponents of the object paradigm often say identifying objects is a simple and intuitive process, experienced developers know that this is not always true. The solution is the CRC (Classes, Responsibilities, Collaboration) Card method, a proven technique for identifying classes and visualizing and testing different class-based models during the design phase.

The CRC Card Book covers the CRC method from start to finish, illustrating its application in three different in-depth case studies which supply tips and pointers drawn from real world experience. The case studies are presented in the engaging style of a novella to demonstrate how personalities and organizational culture come into play when using the CRC technique. C++, Java, and Smalltalk experts provide implementation examples in each language. The CRC Card Book demonstrates how to:

• Discover classes through team brainstorming
• Refine project requirements
• Test the conception of the system and evaluate potential paths of collaboration using role play
• Manage an object-oriented project
• Implement a CRC design in C++, Java, and Smalltalk; all source code is available via the World Wide Web.

Includes language implementation examples from such noted experts as:

• Java: Cay Horstman, San Jose State University
  
• Smalltalk: Larry Smith, IBM Corp.
  
• C++: Jeremy Raw, Interactive Software
