In this chapter, we examined two ways to enhance our collective understanding of a problem domain using two lightweight modeling techniques – domain storytelling and EventStorming.
Domain storytelling uses a simple pictorial notation to share business knowledge among domain experts and technical team members. EventStorming, on the other hand, uses a chronological ordering of domain events that occur as part of the business process to gain that same shared understanding.
Domain storytelling can be used as an introductory technique to establish a high-level understanding of a problem space, while EventStorming can be used to inform detailed design decisions of a solution space.
With this knowledge, we should be able to dive deeper into the technical aspects of solution implementation. In the next chapter, we will start the implementation of business logic and model our aggregate, along with commands and domain events.
