During an intermediate TOGAF interview, you will be questioned about the processes involved in EA designing, the phases involved, and so on. This particular question tests your practical ability in the phases of the business architecture framework. Building an enterprise architecture involves several steps. The two primary considerations are the framework that will be employed and the architectural concepts that will guide all architectural work. The architectural principles that will serve as limitations on any architectural work carried out within the enterprise are defined during the preliminary phase. The very first phase of EA construction is the preliminary phase. In this phase, all the essential elements are defined. Elements like scope, principles, and constraints get defined and described. The Preliminary Phase ensures Commitment to the Process by preparing the Organizational for the Construction of the Architecture.
