Introduce basic concepts and terminology:
Purpose of Enterprise Architecture
The ArchiMate Context
Fundamentally this is a collection of Organisations that share the same goal.
Division of a Corporation
Geographically distant organisations linked by common ownership
The definition of Enterprise has been taken from TOGAF® 9, and reflects the common heritage that
ArchiMate now has.
The definition of an enterprise is very broad, ranging from mega-corporations and government departments, through to a single department. The point being made that in each of these examples is a range IT-related issues that must be handled by the architect.
However, in reality, these “definitions” can also be recognized as examples of types of enterprise, each having their own characteristics that must be accommodated by Enterprise Architecture.
