Enterprise Architecture

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

Snippet from Wikipedia: Enterprise architecture

Enterprise architecture (EA) is a business function concerned with the structures and behaviors of a business, especially business roles and processes that create and use business data. An Enterprise Architect is at the top level of the architect hierarchy. This means they have more responsibilities than solutions architects. While solutions architects focus on their solution, an enterprise architect focuses on the overview of the whole organization. An enterprise architect leads over many solutions architects and business functions. By international consensus, Enterprise Architecture has been defined as "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."
