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.

The Request for Architecture Work is a deliverable that is sent from the sponsor and triggers the start of an architecture development cycle. It defines the scope, budget, schedule, and deliverables for a specific architecture project. The Statement of Architecture Work is a deliverable that is produced by the architect and defines the approach and resources needed to complete an architecture project. It forms the basis of a contractual agreement between the sponsor and the architecture organization. The Architecture Principles are a deliverable that is produced by the architect and defines the general rules and guidelines for the architecture work. They reflect the business principles, business goals, and business drivers of the organization. The Architecture Requirements Specification is a deliverable that is produced by the architect and defines the requirements that govern the architecture work. It covers both functional and non-functional requirements as well as constraints and assumptions. 

This statement best supports the need to govern Enterprise Architecture. Best practice governance enables the organization to control value realization by ensuring that architectures are aligned with the enterprise’s strategy and objectives, meet the quality and performance requirements, and deliver the expected benefits and outcomes. The Architecture Project does not mandate the governance of the target architecture, but rather follows the governance framework established by the enterprise. The TOGAF standard can be used without executive governance, but it is recommended that executive sponsorship and support are obtained for successful architecture development and transition. The Stakeholders preferences may go beyond the architecture project scope and need control, but this is not the primary reason for governing Enterprise Architecture. Reference: The TOGAF® Standard | The Open Group Website, Section 3.3.6 Architecture Governance.

The Architecture Requirements Specification is one of the TOGAF deliverables that provides a set of quantitative statements that outline what an implementation project must do in order to comply with the architecture12. It is a companion to the Architecture Definition Document, which provides a qualitative view of the solution and aims to communicate the intent of the architect. The Architecture Requirements Specification provides a quantitative view of the solution, stating measurable criteria that must be met during the implementation of the architecture3. It typically forms a major component of an implementation contract or contract for more detailed Architecture Definition4. References:
