Nature of Enterprise Architecture
Architecture of the Enterprise
Topic Owner: Peter Bryant
Theme: Influencing TOGAF Next
The Open Group is revising and restructuring The Open Group Architecture Framework (TOGAF) standard. It is experimenting with an ultra-simple set of definitions along the following lines.
System = a collection of components — which can also be called parts — working together to fulfil a mission
System has Architecture
Architecture = fundamental concepts or properties of a system in its environment embodied in its elements, their relationships, and in the principles of its design and evolution
Enterprise = any group of organizations with a common set of goals. For example, an enterprise could be a government agency, a whole corporation, a division of a corporation, a single department, or a chain of geographically distant organizations linked together by common ownership. A large project, or endeavour involving multiple agencies, could also be an enterprise, e.g. London Olympics 2012.
Is this characterisation sufficiently explicit and general for our usage?
Enterprise is a class of System
Enterprise Architecture = Architecture of Enterprise (as System)
At first sight this would seem an ideal definition of Enterprise Architecture from a ESE perspective
- Do you agree?
- Is this characterisation sufficiently explicit and general for normal usage?
- Does this conflict with ‘standard’ definitions of EA from the literature? If so, what will be missed?
- How could the characterisation be improved?
I look forward to your comments
