What
from Wikipedia: Enterprise Architecture is the description of the (current/future)
structure
behaviour
of an organization’s
processes,
information systems,
personnel and
organizational sub-units,
aligned with the organization’s
core goals and
strategic direction.

What
EA is associated strictly with information technology, but it relates more
broadly to the practice of business optimization in that it addresses
business architecture,
performance management,
organizational structure and
process architecture as well.

Who
Modelling the Enterprise Architecture is becoming a common practice
within the U.S. Federal Government to inform the Capital Planning and
Investment Control (CPIC) process. The Federal Enterprise Architecture
(FEA) reference models serve as a framework to guide Federal Agencies in
the development of their architectures. The primary purpose of creating an
enterprise architecture is to ensure that business strategy and IT
investments are aligned. As such, enterprise architecture allows traceability
from the business strategy down to the underlying technology.
Companies such as BP, Intel and Volkswagen AG also have applied
enterprise architecture to improve their business architectures as well as to
improve business performance and productivity.
