OGEA-101 Questions and Answers

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

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.

Phase A: Architecture Vision is the first phase of the Architecture Development Method (ADM) cycle, which is the core of the TOGAF standard. The main purpose of this phase is to define the scope and approach of the architecture development, and to create the Architecture Vision, which is a high-level description of the desired outcomes and benefits of the proposed architecture. To achieve this purpose, this phase focuses on defining the problem to be solved, identifying the stakeholders, their concerns, and requirements, and establishing the business goals and drivers that motivate the architecture work. This phase also involves obtaining the approval and commitment of the sponsors and other key stakeholders, and initiating the Architecture Governance process.

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

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 sectionshould 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.

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. Iterationenables 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.

This statement best supports the need to govern Enterprise Architecture. Best practice governance enables the organization to control value realization by ensuring that architectures are aligned with the enterprise’s strategy and objectives, meet the quality and performance requirements, and deliver the expected benefits and outcomes. The Architecture Project does not mandate the governance of the target architecture, but rather follows the governance framework established by the enterprise. The TOGAF standard can be used without executive governance, but it is recommended that executive sponsorship and support are obtained for successful architecture development and transition. The Stakeholders preferences may go beyond the architecture project scope and need control, but this is not the primary reason for governing Enterprise Architecture. Reference: The TOGAF® Standard | The Open Group Website, Section 3.3.6 Architecture Governance.

The illustration shows the relationship between the Enterprise Continuum, the Architecture Continuum, and the Solutions Continuum, which are key concepts in the TOGAF framework. TheEnterprise Continuum is a view of the Architecture Repository that shows how generic foundation architectures can be leveraged and specialized to support the requirements of an individual organization. The Architecture Continuum specifies a structured classification for architectural artifacts, such as models, patterns, and descriptions, that can be reused and adapted across different domains and levels of abstraction. The Solutions Continuum identifies implemented solutions that support various stages of business and IT capability evolution, such as common systems, industry solutions, and organization-specific solutions. The illustration also shows how the architecture context and requirements are influenced by external factors, such as business drivers, stakeholders, and standards, and how they shape the generic and specific architectures and solutions. The illustration also shows how the deployed solutions become part of the architecture context for future iterations of the architecture development cycle. References:

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 organizationsworking together typically align with broader, often international, scopes of architecture that transcend individual enterprise boundaries.
• Partnerships and alliances of businessesworking 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.

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.

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

 According to the TOGAF template for Architecture Principles, the Rationale section should describe the relationship to other principles, as well as the business benefits and the intentions of adhering to the principle. The Rationale section should use business terminology and point to the similarity of information and technology principles to the principles governing business operations. The Rationale section should also explain how the principle supports the achievement of the business objectives and key architecture drivers. References:

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.

• A-Architecture Repository: This is a part of the Architecture Metamodel that contains artifacts structured according to the metamodel. It includes the Architecture Landscape which is adopted by the enterprise and governed by certain standards and practices.
• B-Governing Board: The Governing Board ensures visibility and escalation, meaning it oversees and manages the capability of the architecture landscape. It plays a crucial role in governance.
• C-Enterprise Capability: This refers to how well an enterprise can execute its mission, meet business objectives or satisfy its stakeholders’ needs and expectations. It’s influenced by both internal factors (like resources, processes) and external ones (like market trends).

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.

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 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

These domains provide a consistent way to describe and understand the architecture from different perspectives, such as business, information, and technology12. Each domain has its own set of concepts, models, views, and artifacts that define the structure and behavior of the architecture within that domain12.

The other options are incorrect because:

•Logical and Physical are not architecture domains, but rather levels of abstraction that can be applied to any domain. Logical architecture describes the functionality and behavior of the system, while physical architecture describes the implementation and deployment of the system3.

•Information and Data are not distinct architecture domains, but rather aspects of the same domain. Information architecture describes the meaning and context of the data, while data architecture describes the structure and format of the data4.

•Capability and Segment are not architecture domains, but rather levels of granularity that can be applied to any domain. Capability architecture describes the current and desired states of a specific business capability, while segment architecture describes a subdivision of the enterprise that has a clear business focus5.

 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 image shows a diagram that illustrates the basic concepts of architecture description as defined by the ISO/IEC/IEEE 42010:2011 standard1, which is also adopted by the TOGAF standard2.
• According to the ISO/IEC/IEEE 42010:2011 standard, an architecture description is a work product used to express an architecture, and it consists of one or more architecture views1.
• An architecture view is a representation of a system from the perspective of a related set of concerns, and it conforms to an architecture viewpoint1.
• An architecture viewpoint is a specification of the conventions for constructing and using an architecture view to address specific stakeholder concerns1.
• Therefore, the correct answer is option A, which identifies the items labeled as “A” and “B” in the image as an architecture viewpoint and an architecture view, respectively. References:
• 1: ISO/IEC/IEEE 42010:2011 - Systems and software engineering — Architecture description1

Based on the illustration, the phase of the ADM labeled as item 2 is the Implementation Governance phase. This phase provides architectural oversight for the implementation. It ensures that the implementation project conforms to the architecture. It also provides a framework for monitoring and managing the implementation.

The Implementation Governance phase involves the following activities:

• Finalizing the Architecture Roadmap and the supporting Implementation and Migration Plan
• Assigning an Architecture Board to oversee the implementation
• Establishing Architecture Contracts with the implementation partners
• Reviewing and approving the implementation project plans and deliverables
• Performing Architecture Compliance reviews to ensure alignment with the architecture
• Performing Architecture Audit reviews to ensure quality and performance of the architecture
• Resolving any architecture issues or change requests that arise during the implementation
• Maintaining the architecture lifecycle and ensuring its continuity

The Implementation Governance phase is essential for ensuring that the architecture is realized as intended and that it delivers the expected business value and outcomes.
