A Business Service represents explicitly defined behavior that a Business Role, Business Actor, or Business Collaboration exposes to its environment.

A Business Service is defined as the externally visible ("logical") functionality, which is meaningful to the environment and is realized by business behaviour (Business Process, Business Function, or Business Interaction).

A Business Service exposes the functionality of Business Roles or Collaborations to their environment. This functionality is accessed through one or more business interfaces. A Business Service is realized by one or more Business Processes, Business Functions, or Business Interactions that are performed by the Business Roles or Business Collaborations, respectively.

The name of a Business Service should preferably be a verb ending with "-ing"; e.g., "transaction processing". Also, a name containing the word "service" may be used.
