OGEA-103 Exam Dumps - TOGAF Enterprise Architecture Combined Part 1 and Part 2 Exam

Comprehensive and Detailed In-Depth Explanation from Expert in Enterprise Architecture, guiding in TOGAF and ArchiMate:

To answer this question correctly, it is necessary to identify the TOGAF-defined deliverables:

Deliverable 3 is the Request for Architecture Work. This document is formally issued by the sponsoring organization to the architecture function to initiate a new ADM cycle or iteration.

Deliverable 4 corresponds to Architecture Requirements, which are expressed as quantitative, testable statements that implementation projects must satisfy to claim architectural compliance.

Why Option A is correct:

The Request for Architecture Work is a key output of Phase A (Architecture Vision). Phase A formally initiates the ADM cycle, establishes scope, stakeholders, constraints, and secures approval to proceed.

Architecture Requirements form a critical input to Architecture Governance, specifically contributing to the plan for how the architecture is governed, including compliance assessments, checkpoints, and governance controls during implementation.

Why the other options are incorrect:

B. Phase A, an assessment of the changes to the architecture: Impact and change assessments are not the primary formation purpose of Architecture Requirements.

C. the Preliminary Phase, an approach to change for the Implementation and Migration Plan: The Request for Architecture Work is not produced in the Preliminary Phase; that phase focuses on establishing Architecture Capability.

D. the Preliminary Phase, a major component of an implementation project: Architecture Requirements guide implementation but are not classified as a “major component” of the project itself.

TOGAF Architecture Requirements Management

TOGAF Architecture Governance Framework

============

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.

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. 

The TOGAF standard divides Enterprise Architecture into four primary architecture domains: business, data, application, and technology. These domains represent different aspects of an enterprise and how they relate to each other. The business domain defines the business strategy, governance, organization, and key business processes. The data domain describes the structure of the logical and physical data assets and data management resources. The application domain provides a blueprint for the individual applications to be deployed, their interactions, and their relationships to the core business processes. The technology domain describes the logical software and hardware capabilities that are required to support the deployment of business, data, and application services. Other domains, such as motivation, security, or governance, may span across these four primary domains. References:

Comprehensive and Detailed Explanation

TOGAF defines an Architecture Principle as a qualitative statement of intent that should be met by the architecture. To ensure clarity and consistent application, TOGAF provides a standard template for documenting each principle. The template includes four parts:

Name – A clear, precise, and easy-to-remember name for the principle.

Answers the question: What is this principle called?

Statement – A short, unambiguous sentence that communicates the essence of the principle.

Answers the question: What does this principle mean?

Rationale – Explains why the principle is important, the benefits of adopting it, and how it supports the enterprise’s goals.

Answers the question: Why should we adopt this principle?

Implications – Highlights the consequences of adopting the principle, including the impact on business processes, technology, governance, and resources.

Answers the question: How does this affect me?

Therefore, the correct section where the reader would find the answer to “How does this affect me?” is Implications.

Why the other options are incorrect

A. Statement: Defines the essence of the principle but does not address consequences.

B. Rationale: Explains the reasoning and justification for the principle but not its practical effects.

C. Name: Only provides the identifier or title of the principle.
