Enterprise Architecture (EA) Frameworks

An enterprise architecture framework (EAF) is essentially a structured tool that outlines how to create and use enterprise architecture. An EAF provides principles and practices for creating and using the architecture description of a system. It structures architects’ thinking by dividing the enterprise into domains, layers, or views and offers models – typically matrices and diagrams – to assist in documenting and understanding the enterprise.

These frameworks are not just for documenting technology. They are used to align IT strategy with business strategy, guide the technology investment decisions and manage the complexity of enterprise systems to ensure that the business as a whole is efficient, agile, and durable.
