Which ADM phase focuses on defining the problem to be solved, identifying the stakeholders, their concerns, and requirements?

Phase A: Architecture Vision is the first phase of the Architecture Development Method (ADM) cycle,

which is the core of the TOGAF standard. The main purpose of this phase is to define the scope and

approach of the architecture development, and to create the Architecture Vision, which is a high-

level description of the desired outcomes and benefits of the proposed architecture. To achieve this

purpose, this phase focuses on defining the problem to be solved, identifying the stakeholders, their

concerns, and requirements, and establishing the business goals and drivers that motivate the

architecture work. This phase also involves obtaining the approval and commitment of the sponsors

and other key stakeholders, and initiating the Architecture Governance process.
