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 an analytical discipline that provides methods to comprehensively define, organize, standardize, and document an organization’s structure and interrelationships in terms of certain critical business domains (physical, organizational, technical, etc.) characterizing the entity under analysis. The goal of EA is to create an effective representation of the business enterprise that may be used at all levels of stewardship to guide, optimize, and transform the business as it responds to real-world conditions. EA serves to capture the relationships and interactions between domain elements as described by their processes, functions, applications, events, data, and employed technologies.
