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

The Architecture Requirements Repository stores all the requirements that are output of the architecture development cycle, as well as the requirements that are input to the architecture development cycle1. The Architecture Requirements Repository includes the following types of requirements1:

•Stakeholder Requirements: These are the high-level requirements and expectations of the stakeholders, derived from the business drivers, goals, and objectives. They are captured and refined in the Architecture Vision phase and the Requirements Management phase.

•Architecture Requirements: These are the detailed requirements that specify what the architecture must do or deliver to meet the stakeholder requirements. They are derived and refined in the Business, Information Systems, and Technology Architecture phases.

•Implementation and Migration Requirements: These are the detailed requirements that specify what the implementation and migration projects must do or deliver to realize the architecture. They are derived and refined in the Opportunities and Solutions and Migration Planning phases.

The Architecture Requirements Repository is used to manage the architecture requirements throughout the architecture lifecycle, ensuring their traceability, consistency, and compliance1. The Architecture Board is the authority that reviews and approves the architecture requirements, as well as the architecture deliverables and artifacts, as part of the architecture governance process2.

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.

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.

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

This statement best describes iteration and the ADM. The ADM is iterative over the whole process between phases and within phases because it allows for feedback loops and refinements at any point in the architecture development and transition process. Iteration enables architects to address changing requirements, assumptions, constraints, and environments; to validate and improve architectures; to manage risks and issues; and to ensure stakeholder satisfaction and value realization. Reference: The TOGAF® Standard | The Open Group Website, Section 3.1 Introduction to the ADM.

The purpose of Enterprise Architecture is to guide effective change by providing a coherent and consistent view of the enterprise’s current and future state, as well as the roadmap and principles for achieving it. Enterprise Architecture helps to align business and IT strategies, optimize resources and investments, reduce complexity and risks, enhance agility and innovation, and deliver value to stakeholders. Reference: The TOGAF® Standard | The Open Group Website, Section 1.3 Executive Overview.

According to the TOGAF Standard, Version 9.2, an architecture view is a representation of a system from the perspective of a related set of concerns1. It consists of one or more architecture models that demonstrate how the system addresses the stakeholder concerns1.

An architecture viewpoint is a specification of the conventions for constructing and using an architecture view to address specific stakeholder concerns1. It defines the perspective, scope, notation, and techniques for creating an architecture view of a system1.

Architects can present architecture views and viewpoints to stakeholders to extract hidden agendas, principles, and requirements that could impact the final Target Architecture, because23:

Architecture views and viewpoints help to communicate and visualize the architecture in a way that is meaningful and relevant to different stakeholders, addressing their specific interests and needs.

Architecture views and viewpoints help to elicit and validate the stakeholder concerns and requirements, ensuring that they are aligned with the business goals and objectives, and that they are consistent and feasible within the architecture context.

Architecture views and viewpoints help to identify and resolve any conflicts, gaps, or trade-offs among the stakeholder concerns and requirements, ensuring that they are balanced and prioritized in the architecture design and decision-making.

Architecture views and viewpoints help to demonstrate and verify the value and benefits of the architecture to the stakeholders, ensuring that they are satisfied and committed to the architecture outcome and governance.

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.

The Implementation Governance Model is a framework that defines the roles, responsibilities, processes, and standards for governing the implementation of the target architecture. It ensures that a project transitioning into implementation also smoothly transitions into appropriate Architecture Governance, which is the practice of ensuring compliance with the enterprise architecture and its principles, standards, and goals. The Implementation Governance Model is part of the Implementation and Migration Plan, which is the output of Phase F: Migration Planning of the Architecture Development Method (ADM)12 References: 1: The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 21: Phase F: Migration Planning 2: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 50: Architecture Governance

The statement "Projects may cycle between ADM phases, in planned cycles covering multiple phases" illustrates the concept of iteration, which is the process of repeating the ADM phases or steps within a phase to refine the architecture outputs and address the changing requirements and stakeholder concerns. Iteration can occur at different levels of granularity and scope, such as within a single phase, across multiple phases, or across the entire ADM cycle. Iteration can also be applied to different architecture domains, such as business, data, application, and technology. Iteration is a key feature of the ADM that enables the development of architectures that are fit for purpose, adaptable, and responsive to change. References: : The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 24: Applying Iteration to the ADM

Business Transformation Readiness Assessment is a joint effort between corporate staff lines of business and IT planners to evaluate the readiness of the organization to undergo change. It involves assessing factors such as vision, commitment, capacity, capability, culture, and motivation that may influence the success of a business transformation initiative. Reference: The TOGAF® Standard | The Open Group Website, Section 3.3.2 Business Transformation Readiness Assessment.

According to the TOGAF Standard, 10th Edition, a stakeholder is “an individual with an interest in a system” 1. A stakeholder can be anyone who is affected by the system, or who can influence or be influenced by the system. Stakeholders can have different roles, perspectives, and concerns regarding the system, and they can be internal or external to the organization. Stakeholder management is a technique that helps to identify, analyze, and engage the stakeholders of an architecture project, and to address their needs and expectations 2. The other options are not correct, as they are not the term used by the TOGAF Standard to describe an individual with an interest in a system. A consumer is “an individual or group that uses a product or service” 1. A lead architect is “an individual who is responsible for leading the development of an architecture” 1. A sponsor is “an individual who provides funding and support for an architecture project” 1. References: 1: TOGAF Standard, 10th Edition, Part I: Introduction, Chapter 3: Definitions. 2: TOGAF Standard, 10th Edition, Part III: ADM Guidelines and Techniques, Chapter 24: Stakeholder Management.

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

According to the TOGAF standard, the objectives of each ADM phase are as follows1:

•Phase E: Opportunities and Solutions

oDetermine whether an incremental approach is required, and if so identify Transition Architectures that will deliver continuous business value

oIdentify and group major work packages within the Architecture Roadmap

oIdentify and group major implementation projects to realize the Architecture Roadmap

oIdentify dependencies between increments and projects

oEstimate cost, benefit, and risk at a high level for each increment and project

oConduct initial prioritization and sequencing of the Architecture Roadmap and projects

•Phase F: Migration Planning

oGenerate the initial complete version of the Architecture Roadmap, based upon the gap analysis and candidate Architecture Roadmap components from Phases B, C, and D

oConfirm the Transition Architectures with relevant stakeholders

oCreate the Implementation and Migration Plan, including Transition Architectures, work packages, projects, and other activities

oConfirm and agree the Architecture Roadmap and Implementation and Migration Plan with relevant stakeholders

•Phase G: Implementation Governance

oFinalize the Architecture Roadmap and the supporting Implementation and Migration Plan

oEnsure conformance with the Target Architecture by implementation projects

oPerform appropriate Architecture Governance functions for the solution and any implementation-driven architecture Change Requests

oEnsure that the architecture lifecycle is maintained

oEnsure that the Architecture Governance Framework is executed

•Phase H: Architecture Change Management

oEnsure that the business value and cost of work packages and Transition Architectures is understood by key stakeholders

oManage risks and issues related to the Architecture Roadmap and Implementation and Migration Plan

oMonitor the implementation projects and Transition Architectures

oManage changes to the architecture baseline

oManage changes to the Architecture Capability

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

•1G: Determine whether an incremental approach is required, and if so identify Transition Architectures that will deliver continuous business value

•2E: Generate the initial complete version of the Architecture Roadmap, based upon the gap analysis and candidate Architecture Roadmap components from Phases B, C, and D

•3F: Finalize the Architecture Roadmap and the supporting Implementation and Migration Plan

•4F: Ensure that the business value and cost of work packages and Transition Architectures is understood by key stakeholders

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. 

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

The Business Transformation Readiness Assessment technique is used to evaluate the readiness of the organization to undergo change and to identify the actions needed to increase the likelihood of a successful business transformation. These actions should be incorporated in the Implementation and Migration Plan, which is the detailed plan to transition from the Baseline Architecture to the Target Architecture. The Implementation and Migration Plan also includes the Transition Architectures, the Architecture Building Blocks, the Work Packages, the Implementation Governance Model, and the Architecture Contract12 References: 1: The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 27: Business Transformation Readiness Assessment 2: The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 21: Phase F: Migration Planning

The table describes the output, outcome, and essential knowledge of an ADM phase that oversees the implementation of changes necessary to reach the adjusted target state. This corresponds to Phase G, also known as Implementation Governance, which ensures that the architecture defined in earlier phases is realized, and it oversees the development and implementation of projects to align with this architecture. The essential knowledge required during this phase includes understanding constraints on the implementation team and adjusting stakeholder priority and preference in response to success, value, effort, and risk of change. References: TOGAF Version 9.1 - 1

“In addition to the method itself being iterative, there is also iteration within the ADM cycle, both among the individual phases and among the steps within a phase.” www.opengroup.org

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:

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.

Building blocks are reusable components of business, IT, or architectural capability that can be combined to deliver architectures and solutions. Building blocks can be defined at various levels of detail, depending on the stage of architecture development. In the earlier phases of the ADM cycle (A to D), building blocks are defined in generic terms, such as logical or physical, to provide a high-level view of the architecture. In Phase E: Opportunities and Solutions, building blocks become implementation-specific, meaning that they are linked to specific products, standards, technologies, and vendors that are available in the market. This phase also identifies the delivery vehicles, such as projects, programs, or portfolios, that will realize the building blocks12 References: 1: The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 23: Phase E: Opportunities and Solutions 2: The TOGAF Standard, Version 9.2, Part IV: Architecture Content Framework, Chapter 36: Building Blocks

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.

According to the TOGAF Standard, 10th Edition, the rationale section of the architecture principles template should highlight the business benefits of adhering to the principle, as well as the business risks of not adhering to it 1. The rationale section should explain the reasoning behind the principle, and provide evidence or arguments to support it. The rationale section should also link the principle to the business drivers, goals, and objectives of the enterprise, and show how the principle contributes to the value and success of the enterprise. The other options are not correct, as they have different purposes in the architecture principles template. The name section should provide a short and memorable name for the principle, such as “Information is an Asset” or “Business Continuity” 1. The statement section should provide a concise and formal statement of the principle, such as “The enterprise’s information is recognized as a core asset, and is managed accordingly” or “The enterprise’s ability to provide critical services and products must be maintained in the event of a disaster” 1. The implications section should identify the impact of the principle on the enterprise, such as the changes, costs, benefits, and risks that may result from applying or violating the principle 1. References: 1: TOGAF Standard, 10th Edition, Part III: ADM Guidelines and Techniques, Chapter 23: Architecture Principles, Section 23.3 Developing Architecture Principles.

“Modeling these items would help the clarification process, and in particular would highlight any ambiguities or conflicts that involved trade-offs and/or prioritization… the architecture principles… likewise help clarify ambiguities or conflicts that involve trade-offs.” Open Group Publications

The scope of an architecture is the extent and level of detail of the architecture work. The scope of an architecture can be defined along four dimensions: project, breadth, depth, and architecture domains. The project dimension considers the boundaries and objectives of the architecture project, such as the time frame, budget, resources, and deliverables. The breadth dimension considers the coverage and completeness of the architecture across the enterprise, such as the organizational units, business functions, processes, and locations. The depth dimension considers the level of detail and specificity of the architecture, such as the granularity, abstraction, and precision of the architectural elements and relationships. The architecture domains dimension considers the aspects or segments of the architecture, such as the business, data, application, and technology domains.

Therefore, the depth dimension is the one that considers to what level of detail the architecting effort should go.

The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 25: Architecture Scope : The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 25.2: Scope Dimensions : The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 25.2.1: Project, Breadth, Depth, and Architecture Domains

One of the key responsibilities of an Architecture Board within the context of TOGAF is to achieve consistency between sub-architectures. This board is typically responsible for overseeing the development and maintenance of the enterprise architecture, ensuring that it aligns with the organization's overall strategy and objectives. They play a critical role in ensuring that all sub-architectures (like Business Architecture, Data Architecture, Application Architecture, and Technology Architecture) work together cohesively and support the overall enterprise architecture vision and strategy.

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.

According to the TOGAF Standard, 10th Edition, architecture governance is “the practice by which enterprise architectures and other architectures are managed and controlled at an enterprise-wide level” 1. Architecture governance ensures that the architecture development and implementation are aligned with the strategic objectives, principles, standards, and requirements of the enterprise, and that they deliver the expected value and outcomes. Architecture governance also involves establishing and maintaining the architecture framework, repository, board, contracts, and compliance reviews 1. The other options are not correct, as they are not the term used by the TOGAF Standard to describe the practice by which the enterprise architecture is managed and controlled at an enterprise-wide level. Corporate governance is “the system by which an organization is directed and controlled” 2, and it covers aspects such as leadership, strategy, performance, accountability, and ethics. IT governance is “the system by which the current and future use of IT is directed and controlled” 2, and it covers aspects such as IT strategy, policies, standards, and services. Technology governance is “the system by which the technology decisions and investments are directed and controlled” 3, and it covers aspects such as technology selection, acquisition, deployment, and maintenance.
