To comprehend a company’s business strategy, we have to analyze its business domain. According to domain-driven design methodology, the analysis phase involves identifying the different subdomains (core, supporting, and generic). That’s how the organization works and plans its competitive strategy.

As you learned in Chapter 1, a subdomain resembles a set of interrelated use cases. The use cases are defined by the business domain and the system’s requirements. As software engineers, we do not define the requirements; that’s the responsibility of the business. Instead, we are analyzing the business domain to identify the subdomains.
