The word design can evoke negative thoughts in the minds of business management. However, DDD is not a heavyweight, high-ceremony design and development process. DDD is not about drawing diagrams. It is about carefully refining the mental model of domain experts into a useful model for the business. It is not about creating a real-world model, as in trying to mimic reality.
The team’s efforts follow an agile approach, which is iterative and incremental. Any agile process that the team feels comfortable with can be used successfully in a DDD project. The model that is produced is the working software. It is refined continuously until it is no longer needed by the business.
