The solution in domain-driven design is trivial: divide the ubiquitous language into multiple smaller languages, then assign each one to the explicit context in which it can be applied: its bounded context.

In the preceding example, we can identify two bounded contexts: marketing and sales. The term lead exists in both bounded contexts, as shown in Figure 3-3. As long as it bears a single meaning in each bounded context, each fine-grained ubiquitous language is consistent and follows the domain experts’ mental models.

In a sense, terminology conflicts and implicit contexts are an inherent part of any decent-sized business. With the bounded context pattern, the contexts are modeled as an explicit and integral part of the business domain.
