Enterprise architecture

“Although many popular information systems planning methodologies, design approaches, and various tools and techniques do not preclude or are not inconsistent with enterprise-level analysis, few of them explicitly address or attempt to define enterprise architectures.”

“The state of the art in software design is the "enterprise architecture", where separate software components implement data processing (or other application specific-tasks), data storage, and user interface functionality. This approach enables, for example, the replacement of a database engine without changing the software components that process the data and those that support the interaction with the user.”

“With increasing size and complexity of the implementations of information systems, it is necessary to use some logical construct (or architecture) for defining and controlling the interfaces and the integration of all of the components of the system.”

“Architecture discussions frequently focus on technology issues. This paper takes a broader view, and describes the need for an "enterprise architecture" that includes an emphasis on business and information requirements. These higher level issues impact data and technology architectures and decisions... There is not a single correct way to develop an architecture or implement standards for every enterprise; they must be customized to the environment.”

“DOD will create a Department-wide blueprint (enterprise architecture) that will prescribe how the Department's financial and non-financial feeder systems and business processes interact. This architecture will guide the development of enterprise-level processes and systems throughout DOD.”

“The Enterprise Architecture is a combination of the Business and Computing architectures. The Computing Architecture, at the least, identifies hardware, software and data communications.”

“When one enterprise architecture dominates, Grumman plans to use it as a "manager of managers." This single, enterprise-wide network-management architecture will run over all other network-management systems being used: no existing scheme will be scrapped.”

“A key ingredient to an enterprise architecture is the ability to link multiple and disparate systems into a coherent whole. has been gradually putting together the technology that will enable it to offer enterprise LANs that are capable of supporting distributed applications running across a variety of computer Internetworking and multi- routing are essential building blocks.”

“Enterprise Architecture Planning (EAP) results in a high-level blueprint of data, applications, and technology that is a cost-effective, long-term solution; not a quick fix. Management participation provides a business perspective, credibility, and de-mystifies the systems planning process. EAP can be labeled as business-driven or data -driven because”

“A company's enterprise architecture is unique — neither good nor bad, but only appropriate or inappropriate in regard to management's vision of the future. The current enterprise architecture either supports the vision or it does not.”

“An enterprise architecture is an abstract summary of some organizational component's design. The organizational strategy is the basis for deciding where the organization wants to be in three to five years. When matched to the organizational strategy, the architectures provide the foundation for deciding priorities for implementing the strategy.”

“It is within the purview of each context to define its own rules and techniques for deciding how the object-oriented mechanisms and principles are to be managed. And while the manager of a large information system might wish to impose some rules based on philosophical grounds, from the perspective of enterprise architecture, there is no reason to make decisions at this level. Each context should define its own objecttivity.”

“An enterprise architecture is a snapshot of how an enterprise operates while performing its business processes. The recognition of the need for integration at all levels of an organisation points to a multi-dimensional framework that links both the business processes and the data requirements. Such a framework is provided by the Information Systems Architecture (ISA) developed by John Zachman.”

“The presence of an enterprise reference architecture aids an enterprise in its ability to understand its structure and processes. Similar to a computer architecture, the enterprise architecture is comprised of several views. The enterprise architecture should provide activity, organizational, business rule (information), resource, and process views of an organization.”

“Most enterprise architectures are obsolete," says Martin, and "most end-to-end processes are clumsy, slow, expensive, and even harmful; they need to be replaced with routines that are fast and focus on the needs of the customer.”

“The term "information technology architecture," with respect to an executive agency, means an integrated framework for evolving or maintaining existing information technology and acquiring new information technology to achieve the agency’s strategic goals and information resources management goals.”

“One could then consider the enterprise-reference architecture to be a meta model of the enterprise representation. The enterprise-architecture is a component of this meta model.”

“Architecture is that set of design artifacts, or descriptive representations, that are relevant for describing an object, such that it can be produced to requirements (quality) as well as maintained over the period of its useful life (change).”

“A conceptual framework that links the Departmental and Programmatic missions, goals, and objectives, and provides a mapping of the current and future DOE business information required to support them.”

“Establishing an enterprise architecture is like reengineering an aircraft in flight.”

“provides a Reference Architecture (known as the CIMOSA cube) from which particular enterprise architectures can be derived. This Reference Architecture and the associated enterprise modelling framework are based on a set of modelling constructs, or generic building blocks, which altogether form the CIMOSA modelling languages.”

“GERAM (The Generalized Enterprise Reference Architecture Methodology) is a class of enterprise architectures and their associated methodologies as developed by the IFAC/IFIP Task Force on Architectures for in their work during the period 1990-1996”

“This book... provides a formal notational system for drawing and maintaining IT architectures, which I call the Enterprise Information Technology Architecture Blueprinting (EAB for short). This methodology adresses the features required of any formal notational system... In short, EAB defines a communications system that allows a community of IT professionals to visualize architectures in a standard manner.”

“Similar to a computer architecture, the enterprise architecture is comprised of several views, including activity view, organizational view, business rule (information) view, resource view, and process view. These views should be cross-referenced with each other to provide an integrated picture of the enterprise.”

“Architecture : The fundamental organization of a system embodied in its components, their relationships to each other, and to the environment, and the principles guiding its design and evolution.”

“An architecture framework is a tool which can be used for developing a broad range of different architectures [architecture descriptions]. It should describe a method for designing an information system in terms of a set of building blocks, and for showing how the building blocks fit together. It should contain a set of tools and provide a common vocabulary. It should also include a list of recommended standards and compliant products that can be used to implement the building blocks.”

“A well-defined enterprise architecture (EA) is a blueprint for institutional modernization and evolution that consists of models describing how an entity operates today and how it intends to operate in the future, along with a plan for how it intends to transition to this future state. Such architectures are essential tools whose effective development and use are recognized hallmarks of successful organizations.”

“Enterprise Architecture is a complete expression of the enterprise; a master plan which "acts as a collaboration force" between aspects of business planning such as goals, visions, strategies and governance principles; aspects of business operations such as business terms, organization structures, processes and data; aspects of automation such as information systems and databases; and the enabling technological infrastructure of the business, such as computers, operating systems and networks”

“An enterprise architecture framework”

“Since the late 1980s, EA Management Frameworks have emerged within the federal government, beginning with the publication of the National Institute of Standards and Technology framework in 1989. In 1992, the GAO issued EA guidance entitled Strategic Information Planning: Framework for Designing and Developing System Architecture. This EA Management Framework was intended to:”

“Enterprise architecture is the organizing logic for business processes and IT infrastructure reflecting the integration and standardization requirements of a company's operation model... The key to effective enterprise architecture is to identify the processes, data, technology, and customer interfaces that take the operating model from vision to reality.”

“Architecture has two meanings depending upon its contextual usage:”

“Enterprise architecture is the organizing logic for business processes and IT infrastructure reflecting the integration and standardization requirements of the company's operating model. The operating model is the desired state of business process integration and business process standardization for delivering goods and services to customers.”

“Enterprise architecture is a management practice to maximize the contribution of an agency’s resources, IT investments, and system development activities to achieve its performance goals. Architecture describes clear relationships from strategic goals and objectives through investments to measurable performance improvements for the entire enterprise or a portion (or segment) of the enterprise”

“In the case of Enterprise Architecture, the most widely read book ever published with this kind of subject or field of study is entitled Enterprise Architecture as Strategy. By reading this book, you will learn that every company has its own architecture, but unfortunately, some just do not have the right one.”

“Enterprise Architecture is the description and visualization of the structure of a given area of contemplation, its elements and their collaborations and interrelations links vision, strategy and feasibility, focusing on usability durability and effectiveness. Architecture enables construction, defining principles, rules, standards and guidelines, expressing and communicating a vision.”

“Enterprise Architecture is the organizing logic for key business processes and IT capabilities reflecting the integration and standardization requirements of the firm’s operating model.”

“What I wanted to do when I came in... was help the community turn a corner and become relevant in the key initiatives that we need in the federal government... make sure architecture was relevant, it became more agile, it continued to move to have a more business and more strategy focus.”
