Prichard 2002 Addison Wesley Design guidelines Use OOD and TDD to produce modular solutions Use OOD for problems that involve data Use TDD to design algorithms for an objects

operations Consider TDD to solve problems that emphasize algorithms over data. Focus on what, not how, when designing ADTs and algorithms. Consider incorporating existing software into your design.
