Normally, the business principles, business goals, and strategic drivers of the organization are already defined elsewhere in the enterprise. The constraints will normally be informed by the business principles and Architecture Principles, developed as part of the Preliminary Phase (see 6. In situations where the architecture framework in place is not appropriate to achieve the desired Architecture Vision, revisit the Preliminary Phase and extend the overall architecture framework for the enterprise. Scoping issues addressed in the Architecture Vision phase will be restricted to the specific objectives for this ADM cycle and will be constrained within the overall scope definition for architecture activity as established within the Preliminary Phase and embodied within the architecture framework. The issues involved in this are discussed in 5.5 Scoping the Architecture. Scoping decisions need to be made on the basis of a practical assessment of resource and competence availability, and the value that can realistically be expected to accrue to the enterprise from the chosen scope of architecture work. Phase A also defines what is in and what is outside the scope of the architecture effort and the constraints that must be dealt with. The issues involved in ensuring proper recognition and endorsement from corporate management, and the support and commitment of line management, are discussed in Part VII, 50.1.4 IT Governance.
Phase A starts with receipt of a Request for Architecture Work from the sponsoring organization to the architecture organization. Obtain approval for a Statement of Architecture Work that defines a program of works to develop and deploy the architecture outlined in the Architecture Vision.Develop a high-level aspirational vision of the capabilities and business value to be delivered as a result of the proposed enterprise architecture.Figure 7-1: Phase A: Architecture Vision 7.1 Objectives It includes information about defining the scope, identifying the stakeholders, creating the Architecture Vision, and obtaining approvals.
