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

(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

“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

Based on the web search results, architecture partitioning is a technique that divides the Enterprise Architecture into smaller and manageable segments or groups, based on various classification criteria, such as subject matter, time, maturity, volatility, etc.12 Architecture partitioning is used to simplify the development and management of the Enterprise Architecture, by reducing complexity, improving governance, enhancing reusability, and increasing alignment and agility12. Therefore, the statement that partitions are used to simplify the management of the Enterprise Architecture is correct.

The other statements are incorrect because:

•Partitions are not equivalent to architecture levels. Architecture levels are different layers of abstraction that describe the Enterprise Architecture from different perspectives, such as strategic, segment, and capability3. Partitions are subsets of architectures that are defined within or across the levels, based on specific criteria1.

•Partitions do not necessarily reflect the organization’s structure. The organization’s structure is one possible criterion for partitioning the architecture, but it is not the only one. Other criteria, such as business function, product, service, geography, etc., can also be used to partition the architecture12.

•Partitions are not defined and assigned to agile Enterprise Architecture teams. Agile Enterprise Architecture is an approach that applies agile principles and practices to the architecture work, such as iterative development, frequent feedback, adaptive planning, and continuous delivery4. Partitions are not a specific feature of agile Enterprise Architecture, but a general technique that can be applied to any architecture method or framework, including TOGAF12.

“The Content Metamodel defines a formal structure for these terms to ensure consistency within the architecture description…” A metamodel used across the enterprise enables consistency and completeness checking of the architecture description against the defined structure. Open Group Publications

The Architecture Landscape is divided into levels known as Segment Strategic and Capability Architectures. These levels correspond to different scopes and purposes of architectures within an enterprise. Segment Architectures are architectures that address specific business units, functions, or processes within an enterprise. Strategic Architectures are architectures that provide a high-level view of the enterprise’s vision, goals, and direction. Capability Architectures are architectures that address specific business capabilities or services that span multiple segments or domains. Reference: The TOGAF® Standard | The Open Group Website, Section 2.4 Architecture Repository.

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, 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.

The Enterprise Continuum provides methods for classifying architecture artifacts as they evolve from generic architectures to Organization-Specific Architectures. Generic architectures are architectures that have been developed for use across a wide range of enterprises with similar characteristics. They provide common models, functions, and services that can be reused and adapted for specific purposes. Organization-Specific Architectures are architectures that have been tailored to meet the needs and requirements of a particular enterprise or a major organizational unit within an enterprise. They reflect the unique vision, goals, culture, structure, processes, systems, and technologies of that enterprise or unit. Reference: The TOGAF® Standard | The Open Group Website, Section 2.3 Enterprise Continuum.

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

An EA Capability is the ability of an organization to perform enterprise architecture effectively and efficiently. It involves establishing and maintaining the appropriate organization structures, roles, responsibilities, skills, processes, tools, and governance mechanisms to support the development and use of enterprise architecture. An EA Capability enables the organization to align its business and IT strategies, deliver value from its investments, manage change and complexity, and improve its performance and agility12 References: 1: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 44: Introduction 2: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 45: Establishing and Maintaining an Enterprise Architecture Capability

Comprehensive and Detailed Explanation

Architecture Partitioning is an ADM technique in TOGAF that addresses how large and complex architectures can be broken down into manageable parts. The intent is to make architecture development more effective, especially in large enterprises with multiple teams, stakeholders, and domains.

Key points from TOGAF:

TOGAF does not mandate a partitioning model. It provides guidelines and techniques to help architects determine whether and how to partition. This means statement 1 is incorrect.

Statement 2: Correct. Architectures may be partitioned to allow different teams to work on different elements in parallel (e.g., by domain, line of business, geographic scope). Partitioning provides clear ownership and reduces overlap or conflict.

Statement 3: Correct. Partitions can be structured in a way that supports architecture re-use, since well-defined partitions (e.g., capability-based or domain-based) enable consistent re-use of architecture building blocks across projects.

Correct Mapping

Statement 1: Incorrect (partitioning is not required by ADM).

Statement 2: Correct.

Statement 3: Correct.

Correct answer is D (2 and 3).

Why the other options are incorrect

A (1, 2 and 3): Incorrect because TOGAF does not require partitioning.

B (1 and 3): Incorrect because 1 is not correct.

C (1 and 2): Incorrect because 1 is not correct.

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

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

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

In the context of TOGAF, a stakeholder is any individual, team, or organization who has interests in, or concerns relative to, the outcome of the architecture. Concerns are those interests which pertain to any aspect of the system’s functioning, development or operation, including considerations such as performance, reliability, and security1. References:

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.

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

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.

Comprehensive and Detailed Explanation

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

This is the objective of Phase F: Migration Planning, where the Implementation and Migration Plan is developed, addressing costs, business value, and stakeholder concerns.

Ensure conformance with the Target Architecture by implementation projects

This is the focus of Phase G: Implementation Governance, which oversees implementation projects, ensuring they align with and conform to the Target Architecture through architecture contracts.

Ensure that the architecture development cycle is maintained

This belongs to Phase H: Architecture Change Management, which ensures the architecture remains relevant, and that the ADM cycle continues in response to new requirements and changes.

Ensure that the Architecture Governance Framework is executed

Also part of Phase H: Architecture Change Management, where governance is continuously applied to manage change effectively.

Correct Mapping

1 → F

2 → G

3 → H

4 → H

Which corresponds to Option A (1F – 2G – 3H – 4H).

Why the other options are incorrect

B. (1H – 2F – 3F – 4G): Incorrect assignment of phases; for example, conformance is not part of Phase F.

C. (1G – 2H – 3H – 4F): Misplaces objectives; conformance is not Phase H, and governance execution is not Phase F.

D. (1F – 2G – 3G – 4H): Incorrect because maintaining the ADM cycle (3) is not Phase G, but Phase H.

The Open Group, TOGAF® 9 Certified Study Guide — outlines ADM phase objectives and their scope.

Phase G: Implementation Governance provides architectural oversight of the implementation. It ensures that the implementation conforms to the Target Architecture using Architecture Contracts and governance frameworks.

Phase H: Architecture Change Management is about maintaining the architecture lifecycle and handling new requirements, not direct implementation oversight.

Preliminary Phase is about setting up the architecture capability.

Phase A is about developing the Architecture Vision.

(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, 10th Edition, the Preliminary Phase of the Architecture Development Method (ADM) has the purpose to develop an Enterprise Architecture Capability 1. An Enterprise Architecture Capability is the ability of the organization to perform the activities and tasks related to Enterprise Architecture, such as defining the scope, principles, vision, governance, and stakeholders of the architecture. The Preliminary Phase also establishes the architecture framework, the architecture repository, the architecture tools, and the architecture team 1. The other options are not correct, as they have different purposes in the ADM. Phase G: Implementation Governance has the purpose to ensure that the implementation projects conform to the target architecture 2. Phase A: Architecture Vision has the purpose to define the scope, stakeholders, business drivers, and objectives of the architecture project 3. Phase B: Business Architecture has the purpose to describe the baseline and target business architecture, and to identify the gaps between them .

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

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

 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.

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.

A business scenario describes business and technology environment in which those problems occur. It provides a realistic context for identifying and addressing business problems and opportunities, as well as their impact on the enterprise’s architecture. Reference: The TOGAF® Standard | The Open Group Website, Section 3.3.1 Business Scenarios.

business and technology environment in which those problems occur https://pubs.opengroup.org/togaf-standard/business-architecture/business-scenarios.html#_Toc68617078 "

A Business Scenario is a uniform description of: - Real business problems - The business and technology environment in which those problems occur - Value streams enabled by capabilities - The desired outcome(s) of proper execution - The human and computing components (the “actors”) who provide the capabilities"

Strategy Portfolio Project Solution Delivery are the four purposes that typically frame the planning horizon, depth and breadth of an Architecture Project, and the contents of the EA Repository. They correspond to different levels of abstraction and granularity in the architecture development process. Reference: The TOGAF® Standard, Version 9.2 - The Open Group, Section 2.4 Architecture Repository.

TOGAF’s governance guidance distinguishes benefits such as transparency, accountability, and discipline in operating governance processes. Formal TOGAF conformance topics include “The benefits of Architecture Governance,” which include establishing and enforcing processes and controls (discipline) for architecture decision-making and compliance. togaf-cert.opengroup.org

Statements 1 and 3 highlight the value and necessity for Architecture Governance to be adopted within organizations. Architecture Governance is the practice and orientation by which Enterprise Architectures and other architectures are managed and controlled at an enterprise-wide level12. It ensures that architectural decisions are aligned with the organization’s strategy, objectives, and standards. Architecture Governance also involves establishing and maintaining processes, decision-making, and mechanisms to avoid or minimize potential conflicts of interest, such as between different stakeholders, business units, or projects34. Moreover, Architecture Governance requires transparency and accountability for all actions implemented and their decision support, so that they can be inspected and evaluated by authorized parties, such as auditors, regulators, or customers5 .

•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

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:
