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

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, Phase E (Opportunities & Solutions) is the first phase that transitions from architecture models into actionable implementation. Within Phase E, architects identify candidate implementation projects or work packages, assess dependencies, cost/benefit, constraints, and derive a highlevel implementation and migration strategy and initial plans. That means the first planning around how to carry out the architecture begins in Phase E. Later phases refine and govern the implementation (e.g. in Phase F and G), but the initial planning belongs in Phase E. Thus Phase E includes the initial implementation planning.

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 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.
