OGEA-102 Exam Dumps - The Open Group Enterprise Architecture Questions and Answers

According to the TOGAF standard, the Target Architecture is the description of a future state of the architecture being developed for an organization. It should be aligned with the Architecture Vision, Principles, and Requirements that have been agreed with the stakeholders. To address the incompatibilities between key stakeholder preferences, the TOGAF standard recommends creating and evaluating multiple alternative Target Architectures that meet different sets of criteria. These criteria should reflect the value preferences and priorities of the stakeholders, as well as the business drivers and objectives. The alternative Target Architectures should be illustrated using a set of architecture views that show the impact of each alternative on the business, data, application, and technology domains. The impact on planned projects should also be identified and analyzed. The strengths and weaknesses of each alternative should be understood and documented. A formal stakeholder review should then be conducted to decide which alternative is the most fit for purpose and should be moved forward with. The funding required for implementing the chosen alternative should also be determined and secured. References:

The scenario states that:

A strategic architecture and roadmap already exist.

Business Architecture is complete, so the work now shifts to Information Systems and Technology Architectures (ADM Phases B–D).

The CTO requires use of the purpose-based EA Capability model (from the TOGAF Series Guide: A Practitioner’s Approach to Developing Enterprise Architecture Following the TOGAF ADM).

The EA team has to plan, organize, and manage the next stage of architecture development, including re-use of existing hardware/software platform components, candidate solutions, feasibility, risks, and prioritization.

Under the purpose-based EA approach, when moving from strategy into defining the next layers of architecture, TOGAF emphasizes:

Using the superior (already-approved) architecture to guide the next ADM cycles– This corresponds to the strategic architecture that is already completed.

Analyzing project dependencies, overlaps, and sequencing

Defining high-level architecture descriptions for the next iteration

Identifying reference architectures and candidate building blocks (especially when reusing existing platform components)

Assessing feasibility, value, cost, and risk for each project

Preparing for stakeholder trade-offs before formalizing the roadmap

These tasks map directly to Option A.

Why Option A is correct

Option A includes exactly what the purpose-based EA approach prescribes at this stage:

“The superior architecture should be used to guide the approach.”✔ Correct — strategic architecture guides the work.

“Review the identified projects, dependencies, and potential overlaps, then decide the order…”✔ Correct — sequencing and dependency assessment are core early tasks in Phases B–D planning.

“Develop high-level architecture descriptions.”✔ Correct — Business Architecture is done; now high-level IS/Tech Architecture descriptions are needed.

“Identify reference architectures and candidate building blocks.”✔ Correct — aligns with TOGAF building-block approach, and specifically fits the scenario where existing platform components will be reused.

“Identify resource needs, considering cost and value.”✔ Correct — mandatory for feasibility and planning.

“Document options, risks, and ways to control them to enable feasibility analysis and trade-off with stakeholders.”✔ Correct — this matches ADM guidelines for preparing options and addressing complexity before deeper development.

This is precisely how TOGAF expects the architecture team to plan, organize, and manage an ADM cycle after strategy is set.

The correct approach is rooted in Phase A: Architecture Vision and the Requirements Management process of the TOGAF ADM (Architecture Development Method).

Stakeholder Management (Phase A): According to the TOGAF standard, one of the first steps in Phase A is to identify stakeholders, their issues, and concerns. The scenario specifically highlights conflicting concerns: efficiency gains vs. job security and cyber resilience. A core TOGAF technique is the assessment of power, influence, and interest . By documenting these " positions, concerns, and cultural factors, " the Enterprise Architect can tailor the Communication Plan and the Architecture Vision to ensure buy-in. This is vital for " architecting with agility, " as it ensures the human and organizational factors are integrated into the design early on.

Defining Views and Viewpoints: TOGAF specifies that the EA team should identify the relevant views for each stakeholder group. For example, a leader worried about security needs a Security View, while an employee worried about job loss needs a Business/Human Resource View. Recording these in the Architecture Vision document ensures that the high-level goals of the AI project align with stakeholder expectations.

Risk Management and Requirements: In TOGAF, risk is not just a technical issue to be handled in Phase G (Implementation Governance) or limited to Security Architecture. It is an integral part of the Architecture Requirements Specification . By recording risk requirements early and using " regular assessments and feedback, " the agency follows a proactive risk management posture. This aligns with the " Requirements Management " circle at the center of the ADM, ensuring that as the AI technology evolves, the risks (like AI hallucinations or data breaches) are continuously monitored against the initial requirements.

Why other options are incorrect:

Option A focuses too heavily on Organization Maps and Business Models. While useful, they don ' t directly address the cultural fears of job loss or the specific risks mentioned in the scenario.

Option B incorrectly suggests waiting until Implementation Governance to consider risk management. In TOGAF, risk must be managed throughout the entire lifecycle, starting as early as possible.

Option C mentions a Communication Plan, but it lacks the formal TOGAF rigor of documenting stakeholder " power and influence " and integrating risk into the " Architecture Requirements Specification. "

At this stage in the scenario:

A strategic architecture has been completed.

All divisions have completed their Architecture Definition Documents.

Work packages have been defined.

Transition Architectures between Baseline and Target are already identified.

A draft roadmap exists for a multi-year phased migration.

You are now asked to plan the next steps for the migration, which aligns exactly with TOGAF ADM Phase F: Implementation and Migration Planning.

In Phase F, TOGAF prescribes the following key activities:

Evaluate and prioritize projects and work packages

Determine business value, cost, risk, dependencies

Confirm Transition Architectures and sequencing

Update and finalize the Implementation & Migration Plan

Option B is the ONLY answer that correctly follows these required TOGAF steps.

✔ Why Option B is correct

Option B states:

“Estimate the business value for each project by applying the Business Value Assessment Technique … to prioritize the migration projects.”✔ This is a TOGAF-recommended technique specifically for Phase F to evaluate and prioritize transformations using value, risk, and ROI.

“Confirm and plan a series of Transition Architecture phases … using a table of Architecture Definition Increments.”✔ Exactly aligned with TOGAF:

Transition Architectures were identified earlier.

In Phase F, they must be confirmed, sequenced, and documented.

“Update the Implementation and Migration Plan.”✔ This is the required output of ADM Phase F.✔ At this point, the plan must be validated and finalized based on value and prioritization.

Thus, Option B directly matches TOGAF’s prescribed migration planning process.

✘ Why the other options are incorrect

A – Incorrect

Suggests finalizing Architecture Definition documentation—this was already completed by each division.

Introduces an “Implementation Governance Model,” which is not a TOGAF artifact at this stage.

Focuses on lessons learned BEFORE execution, which is not appropriate for migration planning.

C – Incorrect

Focuses only on project selection and resource assignment.

Does not use TOGAF techniques for value/risk evaluation.

Does not reference Transition Architectures, which are central in the scenario.

Oversimplifies Implementation & Migration Planning to resource scheduling.

D – Incorrect

Compliance Assessments occur DURING execution, not before migration planning.

At this stage, no implementation has started, so compliance reviews are premature.

Adjusting performance requirements now has no alignment with TOGAF’s ADM sequence.

The correct answer is C, as it aligns with the key TOGAF principles necessary for guiding enterprise architecture in a merger scenario where retail operations and systems are being consolidated.

Analysis of the Principles in Option C:

Common Use Applications

Since the two companies are merging, it is essential to standardize applications across the enterprise.

Using common applications ensures consistency, reduces costs, and improves efficiency.

TOGAF emphasizes this principle to prevent duplicate or redundant systems, which aligns with the CIO’s goal of reducing the number of applications used.

Data is an Asset

In the scenario, a central inventory management system is a core business function.

Treating data as an asset ensures it is managed properly, shared efficiently, and used strategically across the merged organization.

This principle supports the company’s ability to predict demand, adjust stock levels, and automate reordering.

Common Vocabulary and Data Definitions

The merger requires integrating different systems and data structures.

Having a common vocabulary ensures that all stakeholders (stores, fulfillment centers, and digital platforms) use consistent terminology and data definitions.

This minimizes confusion and ensures interoperability across business functions.

Maximize Benefit to the Enterprise

Every architectural decision should focus on the overall benefit to the business.

By consolidating IT systems and reducing redundancies, the company achieves cost savings, which directly supports this principle.

Business Continuity

The stores operate seven days a week, so system changes must ensure uninterrupted service.

Business continuity ensures that customers are not affected during the transition and that critical retail operations (sales, inventory tracking, and fulfillment) remain functional.

Why Other Options Are Incorrect?

Option A: Control Technical Diversity, Interoperability, Data is an Asset, Data is Shared, Business Continuity

Control Technical Diversity is not the primary concern here. The focus is on system consolidation, not necessarily on limiting technology diversity.

Interoperability is important but not as critical as defining a common system and data structure.

Option B: Service Orientation, Compliance with the Law, Requirements-Based Change, Responsive Change Management, Data Security

While service orientation and compliance are valuable, they are not the most relevant to this specific business transition.

Change management and data security are important but do not address the primary enterprise-wide architectural concerns of system consolidation.

Option D: Ease of Use, Common Use Applications, Data is an Asset, Technology Independence, Business Continuity

Ease of Use is beneficial but is not a core architecture principle in this case.

Technology Independence is useful but does not align directly with the scenario’s priority, which is consolidating applications and data structures.

A Request for Architecture Work is a document that describes the scope, approach, and expected outcomes of an architecture project. A Request for Architecture Work is usually initiated by the sponsor or client of the architecture work, and approved by the Architecture Board, which is a governance body that oversees the architecture work and ensures compliance with the architecture principles, standards, and goals. A Request for Architecture Work triggers a new cycle of the Architecture Development Method (ADM), which is the core process of the TOGAF standard that guides the development and management of the enterprise architecture12

An Architecture Vision is a high-level description of the desired outcomes and benefits of the proposed architecture. An Architecture Vision is the output of Phase A: Architecture Vision of the ADM cycle, which is the first phase of the architecture development. An Architecture Vision defines the scope and approach of the architecture work, and establishes the business goals and drivers that motivate the architecture work. An Architecture Vision also involves obtaining the approval and commitment of the sponsors and other key stakeholders, and initiating the Architecture Governance process3

A trade-off analysis is a technique that can be used to evaluate and compare different architecture alternatives and select the most suitable one. A trade-off analysis involves identifying the criteria and factors that are relevant to the decision, such as costs, benefits, risks, and opportunities, and assessing the strengths and weaknesses of each alternative. A trade-off analysis also involves balancing and reconciling the multiple, often conflicting, requirements and concerns of the stakeholders, and ensuring alignment with the Architecture Vision and the Architecture Principles.

Therefore, the best answer is D, because it proposes the best approach for architecture development to realize the CEO’s change in direction for the company. The answer covers the Request for Architecture Work, the Architecture Vision, and the trade-off analysis techniques that are relevant to the scenario.

 1: The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 7: Request for Architecture Work 2: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 50: Architecture Governance 3: The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 18: Phase A: Architecture Vision : The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 30: Trade-Off Analysis

In the context of the TOGAF standard, stakeholder management and addressing stakeholder concerns are critical components, especially for high-impact initiatives like adopting an AI-first approach. Here’s why the selected answer aligns best with TOGAF principles and the scenario:

Stakeholder Analysis and Engagement:Conducting a stakeholder analysis is essential as it helps identify and document the concerns, issues, and cultural factors influencing each stakeholder group. This aligns with TOGAF’s emphasis on understanding and managing stakeholder concerns, particularly in the Preliminary and Architecture Vision phases of the ADM (Architecture Development Method). Since the scenario highlights diverse concerns about AI, understanding each group ' s unique perspective will help the EA team tailor the architecture to address these effectively.

Architecture Vision Document:By documenting these concerns in the Architecture Vision document, the EA team can provide a clear, high-level representation of how AI will be adopted, its benefits, and how it addresses specific stakeholder concerns. This is critical for communicating the intent and value of the AI-first approach in a way that aligns with the agency ' s strategic goals, including addressing apprehensions about job security, skill development, and cyber resilience.

Risk Management and Architecture Requirements Specification:TOGAF highlights the importance of identifying and managing risks early in the process. By documenting the requirements related to risk in the Architecture Requirements Specification, the EA team ensures that these concerns are formally integrated into the architecture and addressed throughout the ADM phases. Regular assessments and feedback loops will provide a mechanism for continual risk monitoring and adjustment as the AI-first initiative progresses.

Alignment with TOGAF’s ADM Phases:The approach specified aligns with TOGAF’s guidance on managing risk and stakeholder concerns during the early ADM phases, specifically Architecture Vision and Requirements Management. In these phases, the framework emphasizes identifying and addressing risks associated with stakeholders ' concerns to build a resilient and widely accepted architecture.

Reference to TOGAF Stakeholder Management Techniques:TOGAF’s stakeholder management techniques underscore the importance of understanding and addressing stakeholder needs as a foundational step. This involves assessing the influence and interest of various stakeholders and integrating their views into architectural development, ensuring that the architecture aligns with both business goals and operational realities.

In conclusion, by conducting a thorough stakeholder analysis and documenting concerns in both the Architecture Vision and Architecture Requirements Specification, the EA team can ensure that stakeholder concerns are addressed, that the architecture supports AI adoption effectively, and that potential risks are managed proactively. This approach will foster acceptance among stakeholders and ensure that the architecture aligns with the agency’s strategic goals and risk management requirements as recommended by TOGAF.

The Chief Engineer is concerned that implementation across multiple plants and mixed teams (internal + contractors) may be inconsistent and of poor quality.

The question asks: How should Architecture Contracts be used to address this concern according to the TOGAF standard?

TOGAF states that an Architecture Contract must:

Define obligations of both architecture and implementation organizations

Specify metrics, measures, acceptance criteria, and success factors

Identify risks and mitigation

Support Architecture Governance through compliance reviews

Apply to BOTH internal teams and external suppliers (external contracts must be legally enforceable)

Option C is the only one that correctly reflects these TOGAF requirements.

✔ Why Option C is correct

1. Architecture Contracts must specify goals, measures, acceptance terms, and risks

TOGAF explicitly states that Architecture Contracts should include:

Statement of Architecture Work

Performance metrics and measures

Acceptance criteria

Risks and issues

Compliance and conformance requirements

Option C includes all of these.

2. Third-party contracts must be legally enforceable

True — TOGAF states that when external suppliers are involved, Architecture Contracts often take the form of legally binding contracts.

Option C:

“Third-party contracts must be legally enforceable.”

Correct.

3. Compliance reviews must be scheduled

TOGAF’s Architecture Governance Framework prescribes scheduled Architecture Compliance Reviews to ensure that implementation conforms to the Architecture Contract.

Option C:

“establish a schedule of compliance reviews at key points”

Correct — this directly addresses the Chief Engineer’s concern about consistency and quality.

4. Deviations must be reviewed by the Architecture Board and any dispensations should be time-bound

TOGAF allows dispensations but requires:

Formal review

Approval by the Architecture Board

Time-bound accommodations rather than permanent exceptions

Option C includes exactly this guidance.

The scenario clearly states that:

The overall objective is known,

BUT the EA team is expected to define the scope, shared vision, and requirements,

The company uses an iterative approach,

The CEO wants repurpose and reuse rather than replace,

This is a major strategic shift (new markets, new products, new crop mix).

According to the TOGAF standard, when the problem must be understood, and scope, vision, and requirements are not yet defined, the correct starting point is Phase A: Architecture Vision, using an iteration cycle.

This is also consistent with the “baseline-first” approach recommended in the TOGAF Series Guides for situations where:

the business direction is known but high-level,

detailed impacts must be discovered,

and the organization wants to reuse existing capabilities rather than replace them.

Option B is the only answer that:

Begins by understanding the problem,

Defines the structure of the change,

Uses iteration cycles starting with a baseline-first approach,

Leads into transition planning,

Supports clarification of the shared vision and requirements,

Fits the CIO’s instruction to “define the scope, shared vision, and requirements.”

This matches exactly what TOGAF prescribes in early-cycle Architecture Vision and initial iterations.

In this scenario, the enterprise is undergoing significant transformation due to a merger and the adoption of new technology (hand-held devices). Several key principles from TOGAF ' s ADM Techniques—particularly those focused on promoting enterprise-wide standardization, adaptability, and data utilization—are pertinent here:

Maximize Benefit to the Enterprise:This principle emphasizes that all architectural decisions should deliver maximum business value. Given that the company is integrating systems to cut costs and improve offerings, maximizing the benefit is crucial. Ensuring that the EA efforts align with enterprise-wide benefits supports the goal of optimizing costs and enhancing offerings, which aligns with the CEO’s vision for the merger.

Common Use Applications:Standardizing applications across the merged entity will be essential to achieve cost savings and to simplify operations. The goal of reducing the number of applications fits with this principle, ensuring that reusable and widely adopted applications support business functions across the organization. Adopting this principle will also aid in harmonizing the systems from both organizations and avoiding unnecessary diversity.

Data is an Asset:Data plays a central role in the company ' s operations, especially with the use of AI-driven inventory management and the integration of systems. Treating data as an asset is essential for reliable and accurate decision-making. This principle ensures that data is viewed as a critical enterprise resource and is managed with care, maintaining integrity, accuracy, and value.

Responsive Change Management:The organization’s ability to adapt quickly and effectively to changes, such as integrating new handheld devices and merging systems, is essential. This principle will facilitate the smooth transition required for integrating the new handheld devices and the merger-related system updates while minimizing disruption to store operations.

Technology Independence:Since the enterprise will likely encounter varied technologies from the merger, it is crucial to maintain flexibility. This principle advocates for using technology solutions that are adaptable and not bound to a single vendor or specific technology. This ensures that the enterprise can integrate various technological components from both organizations and evolve with minimal constraints.

These principles align well with TOGAF ' s broader recommendations for guiding architectural changes, as found in Section 2.6 of the TOGAF ADM Techniques. They ensure that the EA practice is aligned with business objectives while maintaining flexibility, data integrity, and a focus on enterprise-wide benefits. These guiding principles are critical for the successful execution of the integration and adoption of new technologies while achieving cost efficiencies and improving service delivery.

For reference, TOGAF ' s ADM Techniques highlight the importance of architectural principles in guiding transformational initiatives, ensuring that decisions are made consistently across the enterprise. Each principle supports organizational agility, system integration, and the efficient use of technology resources, all of which are vital for the enterprise ' s stated objectives.
