In one of my domain driven-design classes, a participant once noted: “You said that DDD is about aligning software design with business domains. But where are the bounded contexts in real life? There are no bounded contexts in business domains.”

Indeed, bounded contexts are not as evident as business domains and subdomains, but they are there, as domain experts’ mental models are. You just have to be

conscious about how domain experts think about the different business entities and processes.

I want to close this chapter by discussing examples demonstrating that not only are bounded contexts there when we are modeling business domains in software, but the notion of using different models in different contexts is widespread in life in general.
