This question is intended to be dodged to check your theoretical knowledge in enterprise architecture. You can expect this question as it records in all levels of enterprise architecture TOGAF interview questions. As Enterprise architecture is the base of TOGAF, you must know how an EA roadmap works. Start by explaining what a roadmap is and why one is required. An EA roadmap is a visual blueprint that communicates the operations involved in EA and how its goals will get achieved. Such a roadmap will map how the enterprise's business and IT goals can be achieved simultaneously. This roadmap displays all the projects and tasks to arrive at the specific architecture. More specifically, you can say, "The enterprise architecture roadmap includes all the data, business plan, and technical architecture for each project." The EA roadmap lists all the required elements like risk and issues, cost estimates, strategies, success rates, and so on to achieve the proposed architecture.
