Β Readers learn how to use a domain model to make a complex development effort more focused and dynamic. A core of best practices and standard patterns provides a common language for the development team. A shift in emphasisβrefactoring not just the code but the model underlying the codeβin combination with the frequent iterations of Agile development leads to deeper insight into domains and enhanced communication between domain expert and programmer.
