Service Oriented Architecture is the next wave of application
development. Services and SOA are all about designing and building
systems using heterogeneous network addressable software components.
SOA is an architecture with special properties, comprised of
components and interconnections that stress interoperability
and location transparency.
It often can be evolved based on existing system investments
rather than requiring a full scale system rewrite; it leverages
an organization's existing investment by taking advantage of
current resources, including developers, software languages,
hardware platforms, databases, and applications, and will thus
reduce costs and risks while boosting productivity. This adaptable,
flexible style of architecture provides the foundation for shorter
time-to-market and reduced costs and risks in development and
maintenance. Web services is a set of enabling technologies
for SOA, and SOA is becoming the architecture of choice for
development of responsive, adaptive new applications.

A Framework for Information Systems Architecture
In summary, by studying fields of endeavour external to the
information systems community, specifically those professions
involved in producing complex engineering products (eg. architecture/construction,
manufacturing etc), it is possible to hypothesize by analogy
a set of architectural representations for information systems.
The resultant "framework for information systems architecture"
could prove quite valuable for :-
- Improving professional communications within the information
systems community
- Understanding the reasons for and risks of not developing
any one architectural representation
- Placing a wide variety of tools and/or methodologies in
relation to one another
- Developing improved approaches (including methodologies
and tools) to produce each of the architectural representations,
as well as possibly rethinking the nature of the classic "application
development process" as we know it today.

The US Chief Information
Officers (CIO) Council
For information on the Federal Enterprise Architecture Framework
(FEAF) and Enterprise Architecture in general, go to the section
on Enterprise
Architecture. The Federal Enterprise Architecture Framework
(FEAF) was established in the U.S. by the Chief Information
Officers (CIO) council. The FEAF aims to facilitate development
of common architectural approaches amongst government agencies
in the U.S.
Clinger-Cohen
Act
In 1996 the US Congress passed the Information Technology Management
Reform Act. Known as the Clinger-Cohen Act, US Federal agencies
are now required to integrate IT management processes, improve
IT efficiencies and take inventories of all IT equipment. The
Act effectively mandated Enterprise Architecture. This link

of Health Maryland, USA.
C4ISR
Framework
In 1996, the U.S. Air Force introduced the Command, Control,
Comunications, Computers, Intelligence, Surveillance, and Reconnaissance
(C4ISR) Framework as means of collecting, archiving and displaying
defence-related architectural information. In 2003, the Department
of Defence adopted C4ISR as its standard. This link is from
the Armed Forces Communications and Electronics Association
(AFCEA).
C4ISR Case Study
The Enterprise Architecture Interest Group's voluntary professional
membership seeks to influence the practice and development of
a common body of knowledge regarding Enterprise Architecture
(EA). This should help the processes and profession mature while
ensuring the appropriate use of standards, accepted proven methods,
models and best practices. We intend to do this in a collaborative,
governance-based approach that ensures professional acceptance.
