Enterprise Architecture

Enterprise architecture (EA) is the process by which organizations standardize and organize IT infrastructure to align with business goals.

What is Enterprise Architecture?

Enterprise Architecture (EA) is an organizational model; an abstract representation of an Enterprise that aligns strategy, operations and technology to create a roadmap for success. There are many definitions of the word enterprise: in EA, an enterprise is a complex organization that is attempting to undergo change. –
Snippet from Wikipedia: Enterprise architecture

Enterprise architecture (EA) is a business function concerned with the structures and behaviours of a business, especially business roles and processes that create and use business data. The international definition according to the Federation of Enterprise Architecture Professional Organizations is "a well-defined practice for conducting enterprise analysis, design, planning, and implementation, using a comprehensive approach at all times, for the successful development and execution of strategy. Enterprise architecture applies architecture principles and practices to guide organizations through the business, information, process, and technology changes necessary to execute their strategies. These practices utilize the various aspects of an enterprise to identify, motivate, and achieve these changes."

The United States Federal Government is an example of an organization that practices EA, in this case with its Capital Planning and Investment Control processes. Companies such as Independence Blue Cross, Intel, Volkswagen AG, and InterContinental Hotels Group also use EA to improve their business architectures as well as to improve business performance and productivity. Additionally, the Federal Enterprise Architecture's reference guide aids federal agencies in the development of their architectures.
