The Open Group OGEA-103 Dumps - Pass TOGAF Enterprise Architecture Combined Part 1 and Part 2 Exam in 2026

The purpose of the Architecture Roadmap is to provide a high-level view of how the Baseline Architecture will transition to the Target Architecture over time. It lists work packages on a timeline showing progress towards the Target Architecture, as well as dependencies, risks, and benefits. The Architecture Roadmap forms part of the Implementation and Migration Plan and guides the execution of the architecture projects.

The Enterprise Continuum consists of two complementary concepts: the Architecture Continuum and the Solutions Continuum1. The Architecture Continuum provides a consistent way to describe and understand the generic and reusable architecture building blocks, such as models, patterns, and standards, that can be applied and tailored to specific situations2. The Solutions Continuum provides a consistent way to describe and understand the specific and implemented solution building blocks, such as products, services, and components, that realize the architecture building blocks3. The Enterprise Continuum enables the reuse and integration of architecture and solution assets across different levels of abstraction, scope, and detail, ranging from foundation architectures to organization-specific architectures1.

The Enterprise Continuum is used when developing an enterprise architecture to support the following activities1:

*Selecting relevant architecture and solution assets from the Architecture Repository or other sources, based on the business drivers, goals, and requirements

*Adapting and customizing the architecture and solution assets to suit the specific needs and context of the enterprise

*Defining and developing the target architecture and the architecture roadmap, based on the gaps and opportunities identified between the baseline and the target states

*Defining and developing the implementation and migration plan, based on the architecture roadmap and the solution building blocks

*Governing and managing the architecture and solution assets throughout the architecture lifecycle, ensuring their quality, consistency, and compliance

An Enterprise Architecture Capability is the ability of the organization to perform effective and efficient architecture work, including the definition, governance, and management of its architectures2. The Preliminary Phase involves the following activities1:

*Reviewing the organizational context, scope, and drivers for conducting Enterprise Architecture

*Establishing the Architecture Capability desired by the organization, including the maturity level, roles, responsibilities, processes, and tools

*Defining and establishing the Organizational Model for Enterprise Architecture, which describes how the architecture function is organized and integrated within the enterprise

*Defining and establishing the Architecture Governance framework, which provides the mechanisms for ensuring the quality, consistency, and compliance of the architecture work

*Selecting and implementing the tools that support the Architecture Capability, such as repositories, modeling tools, and communication tools

*Defining the Architecture Principles that will guide and constrain the architecture work, based on the business principles, goals, and drivers of the organization

*Defining the Organization-Specific Architecture Framework, which is an adaptation of the generic TOGAF ADM to suit the specific requirements, standards, and practices of the organization

The Preliminary Phase is essential for preparing the organization for the successful development and implementation of its architectures, as well as for ensuring the alignment of the architecture work with the business strategy and objectives1.

The ability to develop, use, and sustain the architecture of a particular enterprise using architecture to govern change is an EA Capability. An EA Capability is a set of skills, processes, roles, responsibilities, tools, and techniques that enable an enterprise to successfully develop and maintain its Enterprise Architecture and achieve its desired outcomes. An EA Capability is part of an enterprise's overall capability portfolio and should be aligned with its strategy and objectives.

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.
