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

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.

Comprehensive and Detailed Explanation From Exact Extract (150–250 words):

Option C is the best answer because it directly aligns with the most critical concerns expressed in the scenario and maps precisely to the example Architecture Principles defined in the TOGAF standard.

The principle Common Vocabulary and Data Definitions is essential in a healthcare environment where standardized medical coding, shared electronic health records, and cross-provider data exchange are core operational requirements. Without consistent data definitions, AI-based solutions would misinterpret clinical information, leading to unsafe or incorrect outcomes.

Data Security is one of the most fundamental principles in regulated industries such as healthcare. The scenario explicitly highlights privacy, prevention of data breaches, system availability, and protection of life-critical systems. This principle ensures confidentiality, integrity, and availability of patient data, all of which are non-negotiable constraints for architecture work in this context.

Requirements-Based Change ensures that architectural decisions are driven by clearly defined business and clinical requirements rather than technology trends alone. This is particularly important for AI initiatives, where stakeholder concerns emphasize patient outcomes, life-critical timing, and minimal disruption. This principle ensures that AI adoption is justified, traceable, and aligned with healthcare priorities.

The other options either focus too broadly on governance, enterprise-wide benefit, or general accessibility, and do not sufficiently address the clinical safety, data integrity, and requirements-driven nature of the project. Therefore, Option C best reflects TOGAF guidance for this scenario.

Business principles business goals, and business drivers provide context for architecture work, by describing the needs and ways of working employed by the enterprise. They define what the enterprise wants to achieve, how it wants to operate, and what factors influence its decisions and actions.

In TOGAF, creating a Business Scenario is a foundational step in defining and understanding the business problem, especially for complex transformations involving multiple stakeholders andsystems, such as in this scenario. This method aligns with Phase A (Architecture Vision) of the TOGAF Architecture Development Method (ADM). Here’s why this approach is the most effective:

Understanding Business Requirements:A Business Scenario provides a structured way to capture and analyze the business requirements, stakeholder concerns, and the contextual elements related to the problem. In this scenario, the company faces challenges in integrating newly acquired companies with existing operations, which includes complex stakeholder concerns across different functional areas. Developing a Business Scenario allows the EA team to break down these complexities into identifiable and manageable parts.

Risk Evaluation and Management:By using the Business Scenario approach, the EA team can not only define the requirements but also assess associated risks systematically. TOGAF emphasizes the importance of risk management through identifying potential risks, evaluating their impact, and defining strategies for handling these risks. The process includes assessing how risks can be avoided, transferred, or reduced—a necessary step in large-scale transformations to ensure that risks are proactively managed.

Residual Risks and Governance:Any risks that cannot be fully resolved should be identified as residual risks and escalated to the Architecture Board, which is aligned with TOGAF’s governance approach. The Architecture Board’s role in TOGAF is to provide oversight and make critical decisions on risks that exceed the control of the EA team. This ensures that unresolved risks are managed at the appropriate level of the organization.

Alignment with TOGAF ADM Phases:The Business Scenario approach directly aligns with the Preliminary and Architecture Vision phases of the TOGAF ADM, which focuses on establishing a baseline understanding of the business context and the strategic transformation required. The detailed understanding of requirements, stakeholder concerns, and risks identified here will guide the subsequent phases of the ADM, including Business Architecture and Information Systems Architecture.

TOGAF Reference (Section 2.6, ADM Techniques):TOGAF provides guidelines on the creation of Business Scenarios as part of ADM Techniques, highlighting the importance of defining a business problem comprehensively to ensure successful transformation. This method includes identification of stakeholders, business requirements, and associated risks, which aligns well with the company's need for strategic and systematic integration of new business units.

By utilizing a Business Scenario, the EA team ensures that all aspects of the transformation are well understood, risks are identified early, and residual risks are managed effectively, aligning with the company's strategic objectives and the TOGAF framework’s guidance on risk management and stakeholder alignment.

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.

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.

In TOGAF, the process of breaking down an initiative into work packages must be grounded in a structured evaluation of gaps, solutions, dependencies, constraints, and implementation factors. Option B precisely follows this guidance. It begins by producing an Implementation Factor Catalog, which is a TOGAF artifact used to record business, technical, regulatory, organizational, and risk considerations that influence implementation. This is especially relevant in the scenario because clinical trials operate under strict regulatory controls, highly sensitive data, and complex coordination across multiple research sites.

Next, Option B calls for creating a gap matrix comparing baseline and target architectures across domains. For each gap, TOGAF requires classification of solution approaches: new development, purchased solution, or reuse of existing components. This aligns directly with the Solutions Continuum and the practice of forming Solution Building Blocks. Grouping similar activities into work packages is also textbook ADM practice, ensuring traceability from architecture gaps into actionable implementation components.

Furthermore, Option B incorporates dependencies analysis and restructures work packages into Capability Increments, which is the TOGAF-recommended method for incremental delivery and Transition Architectures. This matches the scenario's requirement for gradual rollout to minimize disruption to ongoing clinical trials.

Thus, Option B fully reflects the TOGAF standard for structured work package definition.

The Preliminary Phase is the preparatory phase of the Architecture Development Method (ADM) cycle, which sets the context and direction for the architecture work. One of the objectives of this phase is to select and implement tools to support the Architecture Capability, which is the ability of an organization to perform enterprise architecture effectively and efficiently. Tools can include software applications, methods, techniques, standards, and frameworks that assist the architecture development and governance processes. The selection and implementation of tools should be based on the requirements and constraints of the organization, and the alignment with the Architecture Principles and the Architecture Vision3 References: 3: The TOGAF Standard, Version 9.2, Part II: Architecture Development Method (ADM), Chapter 6: Preliminary Phase : The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 45: Establishing and Maintaining an Enterprise Architecture Capability : The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 46: Tools for Architecture Development
