Enterprise Architecture Definitions: Views of the EA Experts on what is Enterprise Architecture

Enterprise architecture is one of the fields that is more relevant than ever but is yet fighting for proving the value and viability. From narrow IT-oriented approaches (Enterprise IT Architecture or EITA) to more broad views, the scope, meaning and the importance of Enterprise Architecture vary. Below are some of the enterprise architecture definitions by some top thinkers and firms.

Enterprise Architecture Definitions Summary:

MITRE

An Enterprise Architecture (EA) translates business vision and strategy into effective enterprise change by creating, communicating and improving the essential requirements, principles, drivers, and models that describe the enterprise’s future state and enable its evolution. The EA establishes the organization-wide roadmap to achieve the mission through optimal performance of its core business functions within an efficient information technology (IT) environment. Enterprise architectures are blueprints; they define the organization’s current (baseline) and desired (target) settings, and specify the mechanisms to transform the enterprise to achieve target outcomes systematically.

GARTNER

Enterprise architecture (EA) is a discipline for proactively and holistically leading enterprise responses to disruptive forces by identifying and analyzing the execution of change toward desired business vision and outcomes. EA delivers value by presenting business and IT leaders with signature-ready recommendations for adjusting policies and projects to achieve target business outcomes that capitalize on relevant business disruptions.

An enterprise architecture (EA) is a conceptual blueprint that defines the structure and operation of an organization. An enterprise architecture intends to determine how an enterprise can most efficiently achieve it’s current and future objectives.

MIT CISR

Enterprise Architecture is the organizing logic for crucial business processes and its capabilities reflecting the integration and standardization requirements of the firm’s operating model.

Archimate Foundation

A coherent whole of principles, methods, and models that are used in the design and realization of an enterprise’s organizational structure, business processes, information systems, and infrastructure

Capgemini

Enterprise architecture is a set of principles, rules, standards, and guidelines, expressing and visualizing a vision and implementing concepts, containing a mixture of style, engineering, and construction principles.”

EACOE Definition of Enterprise Architecture

Defined from an Information & Technology Perspective

Enterprise Architecture is explicitly describing an organization through a set of independent, non-redundant artifacts, explaining how these deliverables interrelate with each other and developing a set of prioritized, aligned initiatives and roadmaps to understand the organization, communicate this understanding to stakeholders, and move the team forward to its desired state.

Defined from a Business Perspective

Enterprise Architecture illuminates how an organization and all of its members can achieve its objectives, through the creation of a series of engineered models and project initiatives, which can be easily understood by all of the people associated with the organization.

ORBUS Software

Enterprise Architecture is a rigorous approach for describing the structure of an enterprise. A well-managed enterprise architecture endeavor results in a responsive and nimble company. Enterprise architecture is three things. Firstly it is a discipline. As a discipline, it is a way of thinking about the structure of an enterprise. An enterprise architect is a professional with know-how, skills, and aptitude in this discipline. Secondly, it is a process. There are processes for architecting an enterprise. They cover how architectures are created, how they evolve and change, and how they are managed. Finally, enterprise architecture is a set of work products – a set of models and representations that describe the structure of an enterprise.
