EA (Enterprise Architecture) frameworks have evolved over time to help organizations align their business strategy and goals with their IT infrastructure. The first EA frameworks were developed in the 1980s and 1990s, with notable examples including Zachman Framework and TAFIM (Technical Architecture Framework for Information Management).

In the early 2000s, a new generation of EA frameworks emerged, such as TOGAF (The Open Group Architecture Framework) and FEAF (Federal Enterprise Architecture Framework), which were designed to be more comprehensive and flexible than their predecessors. Today, there are many different EA frameworks available, each with their own strengths and weaknesses, and organizations may choose to use one or more of them depending on their specific needs and goals.
