What is an external active structure element that represents a point of access where one or more services are provided to the environment?

Comprehensive and Detailed in Depth

An Interface in ArchiMate represents an access point through which elements interact with services.

It can be a Business Interface, Application Interface, or Technology Interface.

Interfaces serve as a boundary between internal and external systems, allowing controlled

interactions. The ArchiMate 3.2 Specification explicitly states that interfaces expose services to the

environment.
