An information technology architecture
and related set of standards are necessary to ensure the compatibility
of the current IT projects and other future IT initiatives. The architecture
and standards provide a blueprint for the development of information technology
applications. The information technology architecture provides a framework
for the development of new applications.

Indiana
The architectural objective upon which
the information technology principles are based is organizational efficiency,
effectiveness and responsiveness. Services provided and functions performed
by agencies of the State of Indiana have as their primary goal the improved
quality of life of Indiana citizens.

An information architecture is a planning
tool which helps develop technically compatible systems by providing a
consistent approach to information technology across an organization. It
is an underlying foundation for dealing in a consistent and integrated
manner with the technology, program and organizational issues in an enterprise.
A well-designed information architecture can help create integrated technical
solutions to program needs and can be used to manage complexity and changing
technology.

The Commonwealth is currently in the process
of establishing networking and computing standards aimed at evolving the
State's computing and networking environments toward greater connectivity
and interoperability. The Governor's Council on Information Technology
(GACIT) has drafted standards for desktop computers, for local area networks,
and for network architecture. This document is the standard for network
management.

The 21st century is approaching quickly,
and the pace of the information revolution is so rapid that we cannot anticipate
the advancements in Information Technology that will change the landscape
of society forever. With that in mind, we describe the future ideal state
in terms of outcomes or experiences that define the improvements that impact
how people will conduct their lives in the year 2000.
In the future, Minnesota citizens will
need to easily access information from all over the world. Technology will
allow them to conduct business across boundaries of geography, culture,
and language. Tasks that were once tedious handwork subject to human intervention
can be handled effortlessly and accurately through technology, giving people
increased time to devote to more rewarding and challenging activities.
An increasingly electronic workplace will create opportunities to reengineer
business operations. For instance, travel costs, crowded freeways, air
and noise pollution can be traded for well-understood performance benchmarks.

The new architecture must accomplish four
major objectives.
-
It must support the business and program priorities
of state government. Technology investments must be channeled in areas
that will give measurable improvements in public service. In particular,
the new architecture must enable the development of systems that facilitate
the implementation of new business processes and the creation of innovative
service delivery approaches.
-
It must enable new applications to be developed
faster and modified quickly, as business needs and program requirements
change.
-
It must simplify the support of operations,
so that the state's technical infrastructure can be managed efficiently
and reliably. The new architecture will prescribe appropriate standards
for technology. As a result, old and new systems will work together, and
the greater use of common components, which will be shared on a statewide
scale, will enable the infrastructure to be managed in a cost-effective
manner.
-
It must enable agencies to continue to capitalize
on the state's existing investment in applications and technology, as appropriate,
while enabling a different approach to implementing systems. New applications
and enhancements to old systems will be built by the assembly of standard,
modular and reusable components.

Ohio
Ohio's chief information officer, together
with the Interagency Information Management Group, realizes that in order
for Ohio’s information technology to progress, a structured, coordinated
effort crossing agency boundaries must exist.
To that end, the state of Ohio will adopt
and implement a standards-based technology information architecture which
assures timely, accurate and cost-effective information delivery from source
to consumer, regardless of the platform, technology or location of either.
The state’s architecture will be a coherent
collection of standards, policies and guidelines that directs the acquisition,
implementation and management of information technology resources.

Oregon
To define a Standards-based Information
Technology Architecture which allows for the development of cost effective,
highly portable applications, which are capable of residing on all processing
levels (desktop workstations to large scale systems), and have a high degree
of interconnectability to support cross organization information access,
message handling, and inter/intra state government communication and data
transfer.

Texas
The AFIRM provides guidance to govern
the evolution of the State infrastructure. The AFIRM does not provide a
specific system architecture. Rather, it provides the services, standards,
design concepts, components and configurations which can be used to guide
the development of architectures that meet specific agency requirements.

Deploying IT resources without an architecture
framework is like constructing a city without plans for rights of ways,
utilities, zoning, building codes and a wide range of other services.

Wisconsin
Wisconsin uses Enterprise Information
Technology projects as one important strategy to implement the State Strategic
Information Technology Plan. Enterprise IT projects assist the state in
managing information technology resources effectively and efficiently at
the enterprise level. Enterprise IT projects are business driven and use
a team-based approach that includes experts in both business and information
technology.

Wyoming
Statewide technology strategy is high
level, broad based and far reaching; therefore, this document is presented
as a planning-oriented, future-focused mechanism that views Wyoming's business-of-state
as an enterprise.

The Stanford University Enterprise Architecture
(version 1.0) is the foundation for building and maintaining modular, dynamic,
and open information systems. The publication of the material included
in this web site marks the first in a series of efforts to describe Stanford
University's information technology architecture, including the underlying
concepts, framework, practical guidelines and implementation. The Enterprise
Architecture will help application and infrastructure projects develop
an institution-wide strategy towards more effective systems.

The decentralization of computing requires
a complimentary level of campus-wide standards, centralized services and
support infrastructure to ensure a reliable, coordinated and interoperable
campus-wide computing environment in which institutional information is
readily accessible as well as secure and well managed.

UC
Office of the President
The University of California's operation
and academic mission depend upon ready access to an increasingly complex
array of electronic information resources. If the University is to realize
the full potential that these resources can offer, support services must
be built that will allow members of the University community to navigate
easily and securely throughout this boundless new Information Environment.
This report summarizes the middle layer of infrastructure that will be
required to achieve these goals

DOD
The Technical Reference Model (TRM) for
IM was the initial effort to bring commonality and standardization to the
technical infrastructure. The TRM addresses the services and standards
needed to implement a common technical infrastructure. A single technical
architecture framework was needed to integrate these efforts and drive
systems design, acquisition, and reuse throughout the DoD.

DOE
This foundation work was the basis for
building blueprints or architectures for ER's data, applications, and technology.
These were integrated into a migration strategy which included a technology
deployment plan and an applications deployment plan.

The Department has numerous stovepiped,
non-integrated systems and technologies. An enterprise-wide blue print
is needed to effectively integrate and interoperate information technologies
and applications throughout the Department.

EPA
EPA's Information Technology Architecture
consists of an organized collection of standards and guidelines to be used
in the technical design of Agency information systems. It provides guidance
for the selection and deployment of computing platforms, networks, system
software, and related products that interconnect computing platforms and
make them operate.

A Federal enterprise architecture
is a strategic information asset base which defines the business,
the information necessary to operate the business, the technologies
necessary to support the business operations, and the transitional processes
for implementing new technologies in response to the changing needs of
the business.

Underlying all the information management
efforts at LMES is the enterprise Business Model which maps all the functionality
performed by Energy Systems into several Corporate Mission Business Areas
and over a dozen supporting Business Areas. This model provides a framework
for categorizing elements of the information management program and helps
to establish ownership for processes and information. This model is not
volatile, but does have to be updated at times to reflect changes in the
mission of the organization.

Information Architecture Planning followed
a proven, structured methodology that takes an enterprise-wide, business-centered
approach toward information management. By determining the information
which supports HAF business activities the HAF can more easily establish
a shared data environment for use by all who need it to do their jobs.
The plan promotes the deployment of applications that benefit the entire
enterprise rather than "stovepipe" applications geared toward the needs
of one organizational unit.
http://www.safaq.hq.af.mil/iap/phase1.html
Treasury
The Department of the Treasury has recognized
the need to carefully rethink its information system development strategies
because the cost of maintaining and implementing "stovepipe" systems is
too expensive. Clearly, it can no longer afford to allow an ad hoc approach
to drive information system development—both technology and market forces
move too fast, and the price of errors is too high.
