ADM Phases & Objectives - Phase A - Architecture Vision:

• To ensure that this evolution of the architecture development cycle has proper recognition and endorsement from the corporate management of the enterprise, and the support and commitment of the necessary line management
  
  
• To define and organize an architecture development cycle within the overall context of the architecture framework, as established in the Preliminary phase
  
  
• To validate the business principles, business goals, and strategic business drivers of the organization and the enterprise architecture Key Performance Indicators (KPIs)
  
  
• To define the scope of, and to identify and prioritize the components of, the Baseline Architecture effort
  
  
• To define the relevant stakeholders, and their concerns and objectives
  
  
• To define the key business requirements to be addressed in this architecture effort, and the constraints that must be dealt with
  
  
• To articulate an Architecture Vision and formalize the value proposition that demonstrates a response to those requirements and constraints
  
  
• To create a comprehensive plan that addresses scheduling, resourcing, financing, communication, risks, constraints, assumptions, and dependencies, in line with the project management frameworks adopted by the enterprise (such as PRINCE2 or PMBOK)
  
  
• To secure formal approval to proceed
  
  
• To understand the impact on, and of, other enterprise architecture development cycles ongoing in parallel
