The Enterprise is
a group of people organized to deliver a product employing technology.
The definition includes people, processes (in "organized") and technology. It is complete because it shows what the term equates to and consists of.
The purpose of the enterprise is the delivery of a product in the most general sense.
the organization of a system and/or its description.
In practice, EA means the organization of the enterprise and its description.
The definitions are proper in the sense that they comply with the initial meanings of the more general terms.
The EA definition assembles the meanings of terms together without adding new ones to the combined terms or invoking superior obscure purposes, as it often happens.
The Description can be consistently, completely and properly realised employing a framework.
An EA Framework is
the scaffolding, that enables the parts to integrate into the whole, and often, in addition, the development methodology.
Too often the scaffolding part is missing from an EA framework rendering the methodology too general to be of practical use.
EA can be done for an entire organization or an unit.
But the enterprise today is not created according to an architecture. Architecture may come in though at a redesign phase for re-engineering the enterprise.
In describing the enterprise, the EA has to document the product delivery, the design activities and the enterprise governance mechanisms for business as usual activities, projects, out of ordinary events etc.
Any Enterprise consists in fact of the following large functions: Governance - Operations (product delivery) - Development - Support .
Hence GODS, a frame and generic business architecture.
The strategy belongs to the enterprise Development function. Strategy has no direct relationship to architecture except that a strategy not based on architecture is hard to realise. The strategy guides the trasformation between the current and the desired state of the enterprise.
