When we think about our Domains, there can be different categories. This is where Domain Facets comes in.

We can start by describing the intrinsic ones. Intrisic phenomena are phenomena that can be found in any instance of the domain, no matter what that specific domain contains. For example, a plane is intrinsic for an Airport because no matter which airport we might utilize to model, they will always have a plane. In contrast, a security checkpoint is not intrinsic to all of the airports because there might be some private airports that don't utilize these checkpoints.

Another facet we can model for s the business processes. Phenomena that are part of the business processes facet are phenomena that are involved with the integral workings of the business. The Passenger Screening Process is one of these.
