Developing Domain Storytelling, or: How DDD influenced modeling practices

Domain Storytelling is a modeling technique that transforms domain knowledge into effective business software. Domain experts and software developers learn from each other by telling stories and drawing them as easy-to-understand pictures. These pictures help to find context boundaries, derive requirements, and design domain models.

In my talk, I will briefly introduce the method and highlight how DDD has influenced modeling practices in general and the development of Domain Storytelling in particular. Key insights that I will discuss:

• Domain language is context-specific and bounded contexts are a game-changer for modeling.
• Software development can be viewed as a series of conversations, facilitated by modeling.
• Eric Evans’ model exploration whirlpool is a powerful, yet underappreciated metaphor for model-driven development.

This talk is for everyone who wants to reflect on their own modeling practices or learn about an additional modeling technique for your DDD toolbox.
