Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it.

Architecture description languages (ADLs) are used in several disciplines: system engineering, software engineering, and enterprise modelling and engineering. The system engineering community uses an architecture description language as a language and/or a conceptual model to describe and represent system architectures .
For example, some EA artifacts can describe the current state of an organization as well as the planned changes to this state in both the short-term and mid-term future, while other EA artifacts can describe some timeless imperatives for an organization which were relevant in the past, are relevant now and will be relevant in the future
