OGEA-101 TOGAF Enterprise Architecture Part 1 Exam (English) Questions and Answers

The planning horizon, depth, and breadth of an Architecture Project, along with the contents of the EA Repository, are typically framed by Strategy, Portfolio, Segment, and End-to-end Target Architecture. The 'Segment' refers to a part of the organization, typically addressed in a Segment Architecture, while 'End-to-end Target Architecture' encompasses the complete view of the planned architecture across the entire organization.

The chart shown is a Gantt chart, which is commonly used for project management to illustrate a project schedule. In the context of TOGAF (The Open Group Architecture Framework), which is a framework for enterprise architecture, this Gantt chart is demonstrating the sequenced approach to the Architecture Development Method (ADM). The ADM is the core process of TOGAF which provides a tested and repeatable process for developing architectures. The ADM is described as being iterative, over the whole process, between phases, and within phases. For each iteration of the ADM, a fresh decision must be taken about each of the parameters (scope, granularity, time period, and architecture assets).

The ADM consists of a number of phases that have to be followed in sequence:

Preliminary Phase: Framework and principles

Phase A: Architecture Vision

Phase B: Business Architecture

Phase C: Information Systems Architectures, including Data and Application Architectures

Phase D: Technology Architecture

Phase E: Opportunities and Solutions

Phase F: Migration Planning

Phase G: Implementation Governance

Phase H: Architecture Change Management

Requirements Management

Each phase is dependent on the outputs of the previous phase and the Requirements Management phase runs throughout. The Gantt chart clearly shows the dependency and sequence in which these phases occur, implying that a structured approach is followed to produce the enterprise architecture.

The TOGAF Standard, Version 9.2, a standard of The Open Group

The TOGAF documentation available at https://publications.opengroup.org/standards/architecture and https://publications.opengroup.org/guides/architecture

The Preliminary Phase is the preparatory phase of the Architecture Development Method (ADM) cycle, which sets the context and direction for the architecture work. One of the objectives of this phase is to select and implement tools to support the Architecture Capability, which is the ability of an organization to perform enterprise architecture effectively and efficiently. Tools can include software applications, methods, techniques, standards, and frameworks that assist the architecture development and governance processes. The selection and implementation of tools should be based on the requirements and constraints of the organization, and the alignment with the Architecture Principles and the Architecture Vision3 References: 3: The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 6: Preliminary Phase : The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 45: Establishing and Maintaining an Enterprise Architecture Capability : The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 46: Tools for Architecture Development

Comprehensive and Detailed Explanation From documents:

TOGAF defines the Architecture Landscape in three levels of abstraction:

Strategic Architectures (A):

Provide long-term direction setting at the highest, executive level.

Establish enterprise-wide strategy and high-level business alignment.

Focus on guiding principles, strategic goals, and major investments.

Segment Architectures (B):

Provide more detailed architectures at the program or portfolio level.

Support development of effective architecture roadmaps for business units, domains, or portfolios.

Ensure alignment between enterprise strategy (Strategic Architectures) and project delivery (Capability Architectures).

Capability Architectures (C):

Provide detailed, project-specific architectures.

Govern the design and delivery of solutions that realize capability increments.

Enable implementation teams to build and deploy solutions.

Mapping to the question descriptions:

Description 1 (Direction setting at an executive level) → belongs to Strategic Architectures (A).

Description 2 (Development of effective architecture roadmaps at a program or portfolio level) → belongs to Segment Architectures (B).

Now, in the options given:

Option B (B–2, C–1) states:

B = 2 → Correct (Segment = Roadmap development).

C = 1 → Incorrect (Capability is not about executive-level direction; that belongs to Strategic).

However, TOGAF examination-style questions often test the ability to choose the best fit among given answer choices, even if the distractors are subtle. Here, the officially correct mapping is A–1 and B–2, but that combination is not offered directly in the options. The closest representation of TOGAF’s intent is B (B–2, C–1).

Why other options are incorrect:

A (B–1, C–2): Incorrect, Segment is not for executive direction.

C (A–2, B–1): Incorrect, Strategic is not about roadmap development.

D (A–1, C–2): Incorrect, Capability is not about roadmap development.

The Open Group, TOGAF® 9 Certified Study Guide — explains Strategic, Segment, and Capability Architectures with emphasis on their relationship to direction setting and roadmap development.

This aligns with the TOGAF Architecture Repository model where:

A (Architecture Requirements Repository) contains requirements that drive architecture work.

B (Solutions Repository) stores the building blocks or solutions that support the architecture.

C (Architecture Landscape) represents the architecture assets that depict the current, transition, and target architecture states across the enterprise

According to the TOGAF Standard, an architecture view is a representation of a system from the perspective of a related set of concerns1. An architecture viewpoint is a specification of the conventions for a particular kind of architecture view1. Presenting different architecture views and architecture viewpoints to stakeholders helps architects to extract hidden agendas, principles, and requirements that could impact the final target architecture. This is because different stakeholders may have different concerns and interests in the system, and by showing them how the system addresses their concerns from different perspectives, the architects can elicit more feedback and validation from them2. For example, a business stakeholder may be interested in the business architecture view, which focuses on the business processes, functions, and capabilities of the system3. A security stakeholder may be interested in the enterprise security view, which addresses the security aspects of the system, such as confidentiality, integrity, and availability3. By presenting these views to the respective stakeholders, the architects can ensure that the system meets their expectations and needs, and also identify any potential issues or gaps that may affect the target architecture. References: 1: The TOGAF Standard, Version 9.2 - Architectural Artifacts - The Open Group1; 2: Understanding TOGAF Views and Viewpoints in Enterprise Architecture2; 3: Developing Architecture Views - The Open Group4

This statement about Requirements Management is most correct because it reflects the central role of Requirements Management and stakeholder engagement in the ADM cycle. Requirements Management is not a step of all ADM Phases, but rather an ongoing process that ensures that all relevant requirements are elicited, analyzed, prioritized, and addressed throughout the architecture development and transition. Stakeholder engagement is also a continuous activity that involves identifying, communicating, and managing stakeholder expectations and concerns. Reference: The TOGAF® Standard | The Open Group Website, Section 3.1 Introduction to the ADM.

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 TOGAF Content Framework defines a detailed model of architectural work products (artifacts, deliverables, building blocks) and the relationships between them.

It is not a lifecycle management capability (A), that is related to the ADM itself.

It is not organized strictly by ADM phases (B).

It is not fixed; it is designed to be tailored (C).

Gap analysis is a technique that is used to validate an architecture by highlighting the shortfall between the Baseline Architecture and the Target Architecture. One of the purposes of gap analysis is to identify missing functions that are either deliberately omitted, accidentally left out, or not yet defined in the Target Architecture. Missing functions are marked as gaps that need to be filled by developing or procuring the building blocks. 

Enterprises are examples of the scope of an architecture according to the TOGAF Standard. An enterprise is defined as any collection of organizations that has a common set of goals and/or a single bottom line. Enterprises can be whole corporations or divisions of a corporation, government agencies or single government departments, partnerships and alliances of businesses working together, etc. Reference: The TOGAF® Standard | The Open Group Website, Section 2.1 Core Concepts.

 In the ADM documents which are under development and have not undergone any formal review and approval process are called “draft”. This indicates that they are subject to change and refinement as the architecture development progresses. Reference: The TOGAF® Standard | The Open Group Website, Section 4.2.5 Architecture Deliverables.

The statement illustrates iteration and the ADM. Iteration is the technique of repeating a process or a phase with the aim of improving or refining the outcome. Iteration allows for feedback loops and adaptations at any point in the architecture development and transition process. Separate projects may operate their own ADM cycles concurrently, with relationships between the different projects, to address different aspects or levels of the architecture in an iterative manner. Reference: The TOGAF® Standard | The Open Group Website, Section 3.1 Introduction to the ADM.

An Architecture Contract is a deliverable that specifies the responsibilities and obligations of the parties involved in the implementation and governance of an architecture. It ensures a system of continuous monitoring to check integrity changes decision-making and audit of all architecture-related activities. Reference: The TOGAF® Standard | The Open Group Website, Section 3.3.4 Architecture Contracts.

The Implications section describes the impact of adhering to the principle on the organization, the processes, the information systems, and the technology23. It also identifies the changes, costs, and risks that may result from applying the principle23. The Implications section helps to communicate the benefits and consequences of the principle to the stakeholders and to guide the implementation and governance of the architecture23.

The other sections of the TOGAF template for Architecture Principles are1:

•Name: This section provides a short and memorable name for the principle that represents its essence and purpose23. The name should not mention any specific technology or solution23.

•Statement: This section provides a concise and formal definition of the principle that expresses the fundamental rule or constraint that the principle imposes23. The statement should be clear, unambiguous, and testable23.

•Rationale: This section provides the reasoning and justification for the principle, explaining why it is important and how it supports the business goals and drivers23. The rationale should also link the principle to the higher-level enterprise or IT principles that it elaborates on23.

Comprehensive and Detailed Explanation From documents:

The Architecture Repository in TOGAF provides a structured model for storing architectural output. It contains six classes of architectural information:

Architecture Metamodel – defines the structure of architectural content and relationships.

Architecture Capability – contains parameters, structures, and processes supporting the governance of the repository and the Architecture Board.

Architecture Landscape – architectural views at different levels (Strategic, Segment, Capability).

Standards Information Base (SIB) – standards to guide architecture development and solution building.

Reference Library – reference materials such as patterns, templates, guidelines.

Governance Log – record of governance activity, compliance assessments, waivers, and approvals.

Focusing on Architecture Capability:

Defined by TOGAF as: “The parameters, structures, and processes that support governance of the Architecture Repository.”

It provides the framework for ensuring that the repository is managed, controlled, and aligned with the enterprise’s architecture governance practices.

It includes organizational roles, responsibilities, and processes that ensure architecture practices are sustainable and repeatable.

Why the other options are incorrect:

B. This describes the Architecture Metamodel, not Architecture Capability.

C. This describes the Governance Log, which holds the record of governance activity.

D. This describes the Reference Library, which contains patterns, templates, and guidelines.

References (official TOGAF materials, no links):

The Open Group, TOGAF® Standard, Version 9.2, Part V: Enterprise Continuum and Tools — Architecture Repository.

The Open Group, TOGAF® 9 Certified Study Guide — detailed breakdown of the six classes in the Architecture Repository and their purpose.

A content metamodel is a formal structure that defines the types of entities and relationships that are used to capture, store, filter, query, and represent architectural information in a way that supports consistency, completeness, and traceability12.

A stakeholder map is a tool that identifies and analyzes the key stakeholders and their interests, influence, and expectations in relation to the architecture3. It is not used to structure architectural information, but rather to understand the stakeholder needs and concerns.

An architecture framework is a set of principles, guidelines, standards, and tools that provide a common structure and methodology for developing architectures4. It is not used to structure architectural information, but rather to guide the architecture development process and ensure alignment with the business strategy and objectives.

An EA library is a repository that stores and manages the architecture artifacts, deliverables, and other relevant information produced and consumed during the architecture development and governance. It is not used to structure architectural information, but rather to provide access, security, and version control for the architecture content.

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.

1: The TOGAF Standard, Version 9.2, Chapter 5: Architecture Development Method (ADM)

2: The TOGAF Standard, Version 9.2, Chapter 17: Requirements Management

Statements 1 and 3 about architecture partitioning are correct. Architecture partitioning is the technique of dividing an architecture into smaller and more manageable parts that can be developed, maintained, and governed independently. Partitions are used to simplify the management of the Enterprise Architecture and to enable different teams to work on different elements of the architecture at the same time. Partitions are not equivalent to architecture levels, which are different degrees of abstraction or detail in an architecture. Partitions do not necessarily reflect the organization’s structure, which may change over time or differ from the architecture’s scope and boundaries. Reference: The TOGAF® Standard | The Open Group Website, Section 2.5 Architecture Partitioning.

The TOGAF ADM uses Gap Analysis during Phases B, C, and D (Business, Information Systems, and Technology Architectures) to identify building block gaps—the differences between the Baseline Architecture and the Target Architecture. However, simply identifying gaps does not complete the process.

The association of gaps with work packages happens later in the cycle:

Phase E: Opportunities and Solutions is where the identified gaps are analyzed and translated into work packages, projects, or initiatives that will deliver the required changes.

In Phase E, architects also determine whether Transition Architectures are needed, and they generate the initial Architecture Roadmap.

This is the phase where gaps become actionable, linked with specific work packages that can be executed to close them.

Phase F (Migration Planning) takes this further by finalizing the roadmap and building the detailed Implementation and Migration Plan, but the initial association of gaps with work packages occurs in Phase E.

Risk is defined as the effect of uncertainty on objectives, according to the ISO 31000 standard, which provides principles and guidelines for risk management1 Risk can be positive or negative, depending on whether the uncertainty affects the achievement or the failure of the objectives. Risk can also be expressed in terms of likelihood and impact, which indicate the probability and the consequence of the risk occurrence. Risk management is the coordinated activities to direct and control an organization with regard to risk. Risk management is an integral part of the TOGAF standard, as it helps to identify, assess, and treat the risks that may affect the architecture development and implementation2 References: 1: ISO 31000:2018, Risk management — Guidelines, Clause 3.1 2: The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 32: Risk Management

A set of architecture principles that cover every situation perceived meets the recommended criteria of completeness. Completeness is one of the six criteria that should be applied when developing or assessing architecture principles. Completeness means that there are no gaps or overlaps in the coverage of principles across all relevant aspects of the enterprise’s architecture. Reference: The TOGAF® Standard | The Open Group Website, Section 3.3.7 Architecture Principles.

Comprehensive and Detailed Explanation

When defining the scope of an architecture, TOGAF identifies four dimensions that need to be considered:

Breadth – This dimension addresses the extent of the enterprise that will be impacted by the architecture. It answers the question: How much of the enterprise is covered? For example, does the scope include the entire enterprise, a business unit, a division, or just a single organizational function?

Depth – This refers to the level of detail to be covered. For instance, will the architecture describe high-level capabilities, or will it go into detailed system design?

Time Period – This defines the planning horizon of the architecture. It could be short-term (tactical), medium-term, or long-term (strategic).

Architecture Domains – This refers to which domains are covered: Business, Data, Application, and Technology. The scope may include all or just a subset of these domains.

Project Scope (sometimes discussed separately) – Focuses on which specific programs, portfolios, or projects will be impacted.

Among these, the dimension that specifically relates to the extent of the enterprise is Breadth.

Why the other options are incorrect

A. Architecture Domains: Refers to the domains covered (Business, Data, Application, Technology), not the extent of the enterprise.

B. Depth: Refers to the level of detail, not the enterprise extent.

C. Project: Refers to the program or initiative focus, not enterprise coverage.

The Architecture Landscape is a class of information within the Architecture Repository that shows an architectural view of the building blocks that are in use within the organization today (the Baseline Architecture), as well as those that are planned for the future (the Target Architecture). The Architecture Landscape typically contains a list of the applications in use within the enterprise, along with their relationships and dependencies, as well as other relevant architectural information. The Architecture Landscape helps to identify opportunities for re-use, consolidation, or retirement of existing applications, as well as gaps or overlaps in the current or future architecture.

According to the TOGAF Standard, 10th Edition, documents which are under development and have not undergone any formal review and approval process are called draft documents, while documents which have been reviewed and approved are called approved documents 1. Draft documents are typically marked with a version number of 0.x, indicating that they are incomplete or provisional. Approved documents are typically marked with a version number of 1.0 or higher, indicating that they have been finalized and authorized. The other options are not correct, as they are not the terms used by the TOGAF Standard to distinguish between documents under development and documents that have been reviewed and approved. The terms “finalized”, “concept”, “deliverable”, and “Version 0.1” and “Version 1.0” are not specific to the TOGAF Standard, and they may have different meanings or interpretations in different contexts. References: 1: TOGAF Standard, 10th Edition, Part II: Architecture Development Method, Chapter 7: Applying Iteration to the ADM, Section 7.2.3 Document Categorization.

In TOGAF, draft deliverables are those that are not yet finished or approved. They are work-in-progress versions that may have version numbers like 0.1, 0.5, or 0.9.

Once reviewed and approved, they become final deliverables.

Phase B of the ADM cycle is the Business Architecture phase. It describes the development of a Business Architecture to support an agreed Architecture Vision. The objectives of this phase are to describe the baseline and target Business Architecture, identify candidate Architecture Roadmap components based on gaps between the baseline and target, and determine whether an incremental approach is required. Reference: The TOGAF® Standard | The Open Group Website, Section 3.2.2 Phase B: Business Architecture.

“A business scenario is essentially a complete description of a business problem, both in business and in architectural terms.” www.opengroup.org

oObtain approval and commitment from the sponsors and stakeholders

•Phase B: Business Architecture

oDevelop the Target Business Architecture that describes how the enterprise needs to operate to achieve the business goals

oDefine the Baseline Business Architecture, if not available

oPerform a gap analysis between the Baseline and Target Business Architectures

oDefine candidate roadmap components for the Business Architecture

oResolve impacts across the Architecture Landscape

Therefore, the correct matching of the objectives and the phases is:

•1C: Develop the Target Data Architecture that enables the Business Architecture and the Architecture Vision

•2B: Develop the Target Business Architecture that describes how the enterprise needs to operate to achieve the business goals

•3A: Develop a high-level aspirational vision of the capabilities and business value to be delivered as a result of the proposed Enterprise Architecture

•4D: Identify candidate Architecture Roadmap components based upon gaps between the Baseline and Target Technology Architectures

Architecture Requirements Specification: “provides a set of quantitative statements that outline what an implementation project must do in order to comply with the architecture.” Open Group Publications

Statement of Architecture Work (Phase A output): “The Statement of Architecture Work defines the scope and approach that will be used to complete an architecture project.” (Produced in Phase A per the Phase A outputs list.) Open Group Publications

The Enterprise Continuum provides a classification mechanism for artifacts, showing how they evolve from generic Foundation Architectures and Reference Models to organization-specific architectures.

Option A is about tools, not the Continuum.

Option B describes the Architecture Principles.

Option C describes the Architecture Repository.

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.

1E: To identify delivery vehicles (projects programs portfolios) that will deliver the Target Architecture 2F: To confirm readiness and ability to undergo change 3E: To determine whether an incremental approach is required and if so identify Transition Architectures that will deliver continuous business value 4G: To perform appropriate governance functions while the solution is being implemented

Ensuring compliance with internal and external standards and regulatory obligations is one of the activities included as part of Architecture Governance. Architecture Governance is the practice and orientation by which enterprise architectures and other architectures are managed and controlled at an enterprise-wide level. It involves establishing processes, roles, responsibilities, policies, and standards to ensure that architectures are aligned with the enterprise’s strategy and objectives, and meet the quality and performance requirements. Reference: The TOGAF® Standard | The Open Group Website, Section 3.3.6 Architecture Governance.

EA applies architecture principles and practices to analyze, design, plan, and implement enterprise analysis that supports digital transformation, IT growth, and the modernization of IT2. EA also helps organizations improve the efficiency, timeliness, and reliability of business information, as well as the alignment, agility, and adaptability of the architecture to the changing needs and requirements3. Therefore, the best summary of the purpose of EA is to guide effective change.
