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

An Architecture Board is an executive-level group responsible for the review and maintenance of the strategic architecture and all of its sub-architectures1. It is a key element in a successful Architecture Governance strategy2.

An Architecture Board is typically made responsible, and accountable, for achieving some or all of the following goals2:

Providing the basis for all decision-making with regard to the architectures

Consistency between sub-architectures

Establishing targets for re-use of components

Flexibility of the Enterprise Architecture: To meet changing business needs To leverage new technologies

Enforcement of Architecture Compliance

Improving the maturity level of architecture discipline within the organization

Ensuring that the discipline of architecture-based development is adopted

Supporting a visible escalation capability for out-of-bounds decisions

Therefore, the correct answer is option D, which captures one of the goals of an Architecture Board as stated in the TOGAF Standard, Version 9.22.

Option A is incorrect, because conducting assessments of the maturity level of architecture discipline within the organization is not a direct responsibility of an Architecture Board, but rather a part of the Architecture Capability Framework3.

Option B is incorrect, because allocating resources for architecture projects is not a direct responsibility of an Architecture Board, but rather a part of the Architecture Governance Framework4.

Option C is incorrect, because creating the Statement of Architecture Work is not a direct responsibility of an Architecture Board, but rather a part of the Architecture Development Method5. 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).

===========

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.

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

Architecture governance is the practice of ensuring compliance with the enterprise architecture and its principles, standards, and goals. Architecture governance provides the means to establish, monitor, and control the architecture development and implementation processes, and to resolve any issues or conflicts that may arise. Architecture governance also ensures that all stakeholders are represented and involved in the decision-making process, and that their interests and concerns are balanced and aligned. Statements 1 and 2 highlight the value and necessity for architecture governance to be adopted within organizations, as they emphasize the importance of responsibility, accountability, fairness, and transparency in the architectural activities. Statements 3 and 4 are more related to the benefits and outcomes of having a good enterprise architecture, rather than the governance aspect.

The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 50: Architecture Governance : The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 29: Architecture Governance

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

According to the TOGAF standard, the need for the ADM process to be governed is to ensure that the architecture development and implementation activities are conducted in a consistent, coherent, and compliant manner1. Governance provides the means to verify that the method is being applied correctly and effectively, and that the architecture deliverables and artifacts meet the quality and standards criteria1. Governance also enables the management of risks, issues, changes, and dependencies that may arise during the ADM process1.

Some of the benefits of governing the ADM process are2:

•Improved alignment of the architecture with the business strategy and objectives

•Enhanced stakeholder engagement and communication

•Increased reuse and integration of architecture assets and resources

•Reduced complexity and duplication of architecture efforts

•Increased agility and adaptability of the architecture to changing needs and requirements

•Improved compliance and auditability of the architecture outcomes and outputs

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.

Architecture partitioning is not the same as architecture levels (so 1 is incorrect).

It allows different teams of architects to work on different parts of the architecture in parallel (2 is correct).

TOGAF does not prescribe a fixed partitioning model; it provides guidance (so 3 is incorrect).

Partitioning is used to simplify management of Enterprise Architecture in large or complex organizations (4 is correct).

“TOGAF defines **‘enterprise’ as any collection of organizations that has a common set of goals. For example, an enterprise could be a government agency, a whole corporation, a division of a corporation, a single department, or a chain of geographically distant organizations linked together by common ownership.” www.opengroup.org

Business scenarios are a technique for capturing, clarifying, and communicating the functional and non-functional requirements of a system. Business scenarios describe the business environment, the actors involved, the desired outcomes, and the processes or rules that govern the behavior of the system. Business scenarios are useful for ensuring that the architecture addresses the real needs and concerns of the stakeholders, and for validating and testing the architecture against expected situations. Business scenarios are developed in Phase A: Architecture Vision of the ADM cycle, and refined and updated throughout the other phases3 References: 3: The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 26: Business Scenarios : The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 18: Phase A: Architecture Vision

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.

According to the TOGAF standard, the deliverables that match the descriptions are as follows:

1 Architecture Principles: These are general rules and guidelines, intended to be enduring and seldom amended, that inform and support the way in which an organization sets about fulfilling its mission1. They reflect a level of consensus among the various elements of the enterprise, and form the basis for making future IT decisions1.

2 Architecture Contracts: These are the joint agreements between development partners and sponsors on the deliverables, quality, and fitness-for-purpose of an architecture2. They are used to ensure that the architecture is implemented and governed according to the agreed-upon specifications and standards2.

3 Request for Architecture Work: This is a document that is sent from the sponsoring organization to the architecture organization to trigger the start of an architecture development cycle3. It defines the scope, schedule, budget, deliverables, and stakeholders of the architecture project3.

4 Architecture Requirements Specification: This is a set of quantitative statements that outline what an implementation project must do in order to comply with the architecture4. It defines the requirements for each architecture domain, as well as the relationships and dependencies among them4.

When considering agile development, Architecture to Support Project will identify what products the enterprise needs, the boundary of the products, and what constraints a product owner has. This defines the enterprise’s backlog. A backlog is a list of features or tasks that need to be done to deliver a product or service. It is prioritized by the product owner based on the value and urgency of each item. Reference: The TOGAF® Standard | The Open Group Website, Section 3.3.5 Architecture to Support Project.

According to the TOGAF Standard, 10th Edition, an architecture contract is “a formal agreement between a service provider and a service consumer that defines the mutual commitments and expectations for the delivery of an architecture” 1. An architecture contract is a governed approach of a particular deliverable that will ensure adherence to the principles, standards, and requirements of the existing or developing architectures, as it specifies the roles, responsibilities, deliverables, quality criteria, and acceptance criteria for the architecture work 1. The other options are not correct, as they are not governed approaches of a particular deliverable, but rather different types of deliverables within the architecture development process. An architecture vision is “a high-level, aspirational view of the target architecture” 1. A statement of architecture work is “a document that defines the scope and approach that will be used to complete an architecture project” 1. An architecture definition document is “a document that describes the baseline and target architectures for one or more domains” 1. References: 1: TOGAF Standard, 10th Edition, Part I: Introduction, Chapter 3: Definitions.

Phase E: Opportunities & Solutions – Steps/Outputs emphasize grouping work packages, dependencies, and planning the roadmap/plan that reflect value/effort:

“Identify and group major work packages… Refine and validate dependencies… Create the Architecture Roadmap & Implementation and Migration Plan.” www.opengroup.org

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.

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

(ADM Inputs/Outputs for early phases include Business Scenario/Architecture Vision content, with “Risks and issues” explicitly listed.) — “Business Scenario / Architecture Vision… Risks and issues …” www.opengroup.org

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.

 1: The TOGAF Standard, Version 9.2 - Content Metamodel 2: TOGAF 9.2 Content Metamodel Framework - A Quick Guide - KnowledgeHut 3: The TOGAF Standard, Version 9.2 - Stakeholder Management 4: The TOGAF Standard, Version 9.2 - Architecture Framework : The TOGAF Standard, Version 9.2 - Architecture Repository

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.

Gap Analysis is a technique that compares the Baseline Architecture and the Target Architecture to identify the differences and gaps between them. The purpose of this technique is to determine the changes and additions that are required to achieve the desired future state of the architecture. One of the main aspects of Gap Analysis is to identify the functions that are missing or overlapping in the current and future architectures, and to plan how to address them. This helps to ensure that the architecture is complete, consistent, and aligned with the business objectives and requirements3

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 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.

(Authoritative Open Group guidance distinguishes conceptual, logical, and physical concerns; at the logical level, component types are identified independently of implementation.) For example, the Open Group’s metamodel guidance emphasizes technology-agnostic structure to ensure consistency within an architecture description, which is precisely what the logical level captures before physical realization.

“The Content Metamodel defines a formal structure… to ensure consistency within the architecture description and also to provide guidance for organizations that wish to implement their architecture within an architecture tool.” Open Group Publications

According to the TOGAF Standard, Version 9.2, the ADM phases and their objectives are as follows1:

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.

Requirements Management: To manage the architecture requirements throughout the ADM cycle, and to ensure alignment with the business requirements.

Based on the above definitions, we can match each objective with the corresponding phase as follows:

Objective 1: Ensure that the business value and cost of work packages and transition architectures is understood by key stakeholders. This objective is achieved in Phase H: Architecture Change Management, where the value realization and cost-benefit analysis of the architecture are performed2.

Objective 2: Ensure conformance with the Target Architecture by implementation projects. This objective is achieved in Phase F: Migration Planning, where the conformance requirements and criteria for the implementation projects are defined3.

Objective 3: Ensure that the architecture development cycle is maintained. This objective is achieved in Phase F: Migration Planning, where the architecture roadmap and iteration cycle are maintained3.

Objective 4: Ensure that the Architecture Governance Framework is executed. This objective is achieved in Phase G: Implementation Governance, where the architecture governance processes and procedures are applied to the implementation projects4.

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

The class of information known as the Reference Library within the Architecture Repository contains guidelines and templates used to create new architectures. The Reference Library provides a set of resources that can be leveraged or customized for specific architecture development purposes. It includes generic building blocks, patterns, models, standards, frameworks, methods, techniques, best practices, etc. Reference: The TOGAF® Standard | The Open Group Website, Section 2.4 Architecture Repository.

Risk Management is the process of identifying, assessing, and responding to risks that may affect the achievement of the enterprise’s objectives. Risk Management involves balancing positive and negative outcomes resulting from the realization of either opportunities or threats. Reference: The TOGAF® Standard | The Open Group Website, Section 3.3.3 Risk Management.

The four dimensions used to scope an architecture are Breadth, Depth, Time Period, and Architecture Domains1, p. 8.

Breadth refers to the extent of the enterprise covered by the architecture, which can range from a specific business unit to the entire organization1, p. 8.

Depth refers to the level of detail and completeness of the architecture, which can vary depending on the purpose, scope, and stakeholders of the architecture1, p. 8.

Time Period refers to the temporal aspects of the architecture, such as the current state, the target state, and the transition plan1, p. 8.

Architecture Domains refers to the classification of the architecture into four domains: Business, Data, Application, and Technology1, p. 8.

These four dimensions help define the scope and boundaries of the architecture and ensure that it meets the needs and expectations of the stakeholders.

1: The Open Group (2018). The TOGAF® Standard, Version 9.2. 1

Risk management is a generic technique that can be applied across all phases of the Architecture Development Method (ADM), as well as in the Preliminary Phase and the Requirements Management Phase2. Risk management involves the following steps1:

•Risk identification: This step involves identifying the potential risks that may affect the architecture project, such as technical, business, organizational, environmental, or legal risks. The risks can be identified through various sources, such as stakeholder interviews, workshops, surveys, checklists, historical data, or expert judgment.

•Risk classification: This step involves categorizing the risks based on their nature, source, impact, and priority. The risks can be classified according to different criteria, such as time, cost, scope, quality, security, or compliance. The classification helps in prioritizing the risks and allocating resources and efforts to address them effectively.

•Initial risk assessment: This step involves assessing the likelihood and impact of each risk, and determining the initial level of risk. The likelihood is the probability of the risk occurring, and the impact is the severity of the consequences if the risk occurs. The initial level of risk is the product of the likelihood and impact, and it indicates the urgency and importance of the risk. The initial risk assessment helps in identifying the most critical risks that need immediate attention and mitigation.

Comprehensive and Detailed Explanation

Let’s examine each statement against the TOGAF ADM principles:

All ADM activities are carried out within an iterative cycle of continuous architecture definition and realization

Correct. The ADM is iterative in three dimensions: across the cycle, between levels (enterprise, segment, capability), and within phases. This means architecture development is never linear but part of a continuous cycle of definition and realization.

The Requirements Management phase is a continuous phase

Correct. Requirements Management is central to the ADM cycle. It operates continuously, ensuring requirements are identified, stored, and addressed throughout all phases, not only in a single step.

Output from an early phase may be modified in a later phase

Correct. The ADM is iterative and allows feedback between phases. For example, new requirements identified in later phases may lead to modifications of deliverables from earlier phases.

When a phase starts, the previous phase closes

Incorrect. The ADM is not strictly sequential. Phases can overlap, iterate, and provide feedback loops. One phase starting does not imply that the previous phase is closed; instead, phases interact dynamically.

Correct Mapping

Statements 1, 2, and 3 are correct.

Statement 4 is incorrect.

Correct answer is B (1, 2 & 3).

Why the other options are incorrect

A (2, 3 & 4): Includes statement 4, which is incorrect.

C (1, 2 & 4): Includes statement 4, which is incorrect.

D (1, 3 & 4): Includes statement 4, which is incorrect.
