What is enterprise architecture?
Enterprise architecture (EA) is the practice of analyzing, designing, planning and implementing enterprise analysis to successfully execute on business strategies. EA helps businesses structure IT projects and policies to achieve desired business results and to stay on top of industry trends and disruptions using architecture principles and practices, a process also known as enterprise architectural planning (EAP).
EA began in the 1960s, born from “various architectural manuscripts on Business Systems Planning (BSP) by Professor Dewey Walker,” according to the Enterprise Architecture Book of Knowledge (EABOK). John Zachmann, one of Walker’s students, helped formulate those documents into the more structured format of EA. Both men also worked for IBM during this time, and that’s when Zachman published the framework in the IBM Systems Journal in 1987.
