What is Enterprise-Wide Technical Architecture (EWITA)?
(as extracted from various documents)

Kentucky -
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.

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.

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.

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.

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 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.

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.

Cal State Northridge
"Enterprise Architecture is an initiative to provide integrated electronic information and processes that enable the success of the University’s mission."

Standford University
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.

UC Berkeley
An ITA is a set of information technology principles, standards, guidelines, and statements of direction intended to facilitate and promote the design and purchase of interoperable systems. Appropriate architecture leads to savings in delivery time, price, training, support, and maintenance.

UC Davis
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 Irvine
Software Architecture research is directed at reducing the cost of application development by focusing attention on high level design issues and increasing reuse.

In order to continue providing high quality administrative computing services to the campus users, AIS needs to make sure that it maintains a strategic technology direction, keeps current with industry developments, and employs the selected technologies appropriately

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

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.

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'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.

Los Alamos Lab
The IA project is the Laboratory-wide effort to develop the framework for the selection, implementation, and support of computing and communications products and services.

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.

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.
