This document outlines the steps for developing an enterprise architecture using frameworks like TOGAF 9 and existing governance models. It discusses establishing an enterprise architecture program, defining the framework and segments, developing governance, and obtaining approvals. The process then involves defining the vision and scope, conducting gap and impact analyses, populating architecture models, and developing work products across phases from the framework. Projects and a roadmap are developed using the outputs to implement the architecture.
