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:

The image shows a diagram that illustrates the basic concepts of architecture description as defined by the ISO/IEC/IEEE 42010:2011 standard1, which is also adopted by the TOGAF standard2.

According to the ISO/IEC/IEEE 42010:2011 standard, an architecture description is a work product used to express an architecture, and it consists of one or more architecture views1.

An architecture view is a representation of a system from the perspective of a related set of concerns, and it conforms to an architecture viewpoint1.

An architecture viewpoint is a specification of the conventions for constructing and using an architecture view to address specific stakeholder concerns1.

Therefore, the correct answer is option A, which identifies the items labeled as “A” and “B” in the image as an architecture viewpoint and an architecture view, respectively. References:

Comprehensive and Detailed Explanation

The TOGAF ADM defines distinct objectives for Phase E (Opportunities and Solutions) and Phase F (Migration Planning).

Phase E: Opportunities and Solutions

Focuses on generating the initial Architecture Roadmap.

Identifies major work packages, Transition Architectures, and projects.

Determines if an incremental approach is needed, and defines Transition Architectures to ensure delivery of continuous business value.

Therefore:

Statement 1 (incremental approach and Transition Architectures) belongs to Phase E.

Statement 2 (initial Architecture Roadmap based on gap analysis) also belongs to Phase E.

Phase F: Migration Planning

Finalizes the Architecture Roadmap.

Develops the detailed Implementation and Migration Plan.

Ensures stakeholders understand the business value and cost of work packages and Transition Architectures.

Therefore:

Statement 3 (finalizing the Roadmap and Plan) belongs to Phase F.

Statement 4 (ensuring value and cost are understood by stakeholders) belongs to Phase F.

Correct Mapping

Phase E Objectives = Statements 1 and 2

Phase F Objectives = Statements 3 and 4

Thus the correct answer is A (1 & 2).

===========

The Preliminary Phase establishes the Organization Model for Enterprise Architecture, defines principles, and sets up the Architecture Capability.

The Architecture Vision is developed in Phase A.

The Architecture Roadmap comes from Phase E and Phase F.

The Implementation Governance Model is part of Phase G.

According to the TOGAF standard, the two statements provided refer to different scopes within which architecture can be developed:

Groups of countries, governments, or governmental organizations working together typically align with broader, often international, scopes of architecture that transcend individual enterprise boundaries.

Partnerships and alliances of businesses working together, such as a consortium or supply chain, refer to collaborative efforts that can define architecture at a scope involving multiple enterprises.

In both cases, the term "Architectures Scopes" is appropriate because it reflects the varying levels and contexts in which architectures can be defined, ranging from single business units to collaborative inter-organizational efforts.

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 TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 5: Introduction to the ADM : The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 18: Phase A: Architecture Vision : The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 18.3: Inputs : The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 18.4: Steps

These domains provide a consistent way to describe and understand the architecture from different perspectives, such as business, information, and technology12. Each domain has its own set of concepts, models, views, and artifacts that define the structure and behavior of the architecture within that domain12.

The other options are incorrect because:

•Logical and Physical are not architecture domains, but rather levels of abstraction that can be applied to any domain. Logical architecture describes the functionality and behavior of the system, while physical architecture describes the implementation and deployment of the system3.

•Information and Data are not distinct architecture domains, but rather aspects of the same domain. Information architecture describes the meaning and context of the data, while data architecture describes the structure and format of the data4.

•Capability and Segment are not architecture domains, but rather levels of granularity that can be applied to any domain. Capability architecture describes the current and desired states of a specific business capability, while segment architecture describes a subdivision of the enterprise that has a clear business focus5.

The illustration shows an architecture development cycle based on the TOGAF ADM (Architecture Development Method), which is a method for developing and managing an enterprise architecture1.

The ADM consists of nine phases, each with a specific purpose and output. The phases are1:

Preliminary Phase: To prepare and initiate the architecture development cycle, including defining the architecture framework, principles, and governance.

Phase A: Architecture Vision: To define the scope, vision, and stakeholders of the architecture initiative, and to obtain approval to proceed.

Phase B: Business Architecture: To describe the baseline and target business architecture, and to identify the gaps between them.

Phase C: Information Systems Architectures: To describe the baseline and target data and application architectures, and to identify the gaps between them.

Phase D: Technology Architecture: To describe the baseline and target technology architecture, and to identify the gaps between them.

Phase E: Opportunities and Solutions: To identify and evaluate the opportunities and solutions for implementing the target architecture, and to define the work packages and transition architectures.

Phase F: Migration Planning: To finalize the implementation and migration plan, and to ensure alignment with the enterprise portfolio and project management.

Phase G: Implementation Governance: To provide architecture oversight and guidance for the implementation projects, and to manage any architecture change requests.

Phase H: Architecture Change Management: To monitor the changes in the business and technology environment, and to assess the impact and performance of the architecture.

In addition to these phases, there is a central process called Requirements Management, which is labeled as item 1 in the illustration. This process operates throughout the ADM cycle, and its purpose is to manage the architecture requirements throughout the architecture development, ensuring that they are aligned with the business requirements and the stakeholder concerns2.

Therefore, the description that matches the phase of the ADM labeled as item 1 is C. Operates the process of managing architecture requirements.
