Enterprise architecture
From Wikiquote
Enterprise architecture (EA) is the science of designing an enterprise in order to rationalize its processes and organisation. In practice it is the process of translating business vision and strategy into effective enterprise change by creating, communicating and improving the key requirements, principles and models that describe the enterprise's future state and enable its evolution.

1980s [edit]
- 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.
- John Zachman (1987) "A framework for information systems architecture". In: IBM Systems Journal, Vol 26, Issue 3, p.276
- 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.
- W. Bradford Rigdon (1989) "Architectures and Standards". In: Information Management Directions: The Integration Challenge E.N. Fong and A.H. Goldfine (eds.). NIST Sept 1989. p.136
- Architecture is defined as a clear representation of a conceptual framework of components and their relationships at a point in time... a discussion of architecture must take into account different levels of architecture. These levels can be illustrated by a pyramid, with the business unit at the top and the delivery system at the base. An enterprise is composed of one or more Business Units that are responsible for a specific business area. The five levels of architecture are Business Unit, Information, Information System, Data and Delivery System. The levels are separate yet interrelated... The idea if an enterprise architecture reflects an awareness that the levels are logically connected and that a depiction at one level assumes or dictates that architectures at the higher level.

- 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.

1990s [edit]
- A key ingredient to an enterprise architecture is the ability to link multiple and disparate systems into a coherent whole.
- Karyl Scott (1992). "Enterprise computing". In: InfoWorld. Vol 14, nr.28, p.96.
- Although the concept of an enterprise architecture (EA) has not been well defined and agreed upon, EAs are being developed to support information system development and enterprise reengineering. Most EAs differ in content and nature, and most are incomplete because they represent only data and process aspects of the enterprise. This paper defines an EA... An EA is a conceptual framework that describes how an enterprise is constructed by defining its primary components and the relationships among these components.

- There can be no enterprise architecture without a direct connection to governance.

- There is no such thing as a standard enterprise architecture. Enterprise design is as unique as a human fingerprint, because enterprise differ in how they function. Adopting an enterprise architecture is therefore one of the most urgent tasks for top executive management. Fundamentally, and information framework is a political doctrine for specifying as to who will have what information to make timely decisions.
- Paul A. Strassmann (1995). The politics of information management: policy guidelines. p.53
- Enterprise architecture. This is the Holy Grail of all systems people. Advanced systems textbooks tell you that every organization must have one. Several CIM program directors attempted to come up with this abstraction, only to fail. Only someone with a depth of understanding about how the Pentagon really works could come up with anything of use."
- Paul A. Strassmann (1995). The politics of information management: policy guidelines. p.422
- Enterprise architecture is a family of related architecture components. This include information architecture, organization and business process architecture, and information technology architecture. Each consists of architectural representations, definitions of architecture entities, their relationships, and specification of function and purpose. Enterprise architecture guides the construction and development of business organizations and business processes, and the construction and development of supporting information systems... Enterprise architecture is a holistic representation of all the components of the enterprise and the use of graphics and schemes are used to emphasize all parts of the enterprise, and how they are interrelated."

- 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.

- The goal of enterprise architecture is to create a unified IT environment (standardized hardware and software systems) across the firm or all of the firm's business units, with tight symbiotic links to the business side of the organization (which typically is 90% of the firm... at least by way of budget). More specifically, the goals are to promote alignment, standardization, reuse of existing IT assets, and the sharing of common methods for project management and software development across the organization.
