oDevelop the Target Business Architecture that describes how the enterprise needs to operate to achieve the business goals oDefine the Baseline Business Architecture, if not available oPerform a gap analysis between the Baseline and Target Business Architectures oDefine candidate roadmap components for the Business Architecture oResolve impacts across the Architecture Landscape
*Phase C: Information Systems Architecture
oDevelop the Target Data Architecture that enables the Business Architecture and the Architecture Vision oDevelop the Target Application Architecture that supports the Business Architecture and the Architecture Vision oDefine the Baseline Data and Application Architectures, if not available oPerform a gap analysis between the Baseline and Target Data and Application Architectures oDefine candidate roadmap components for the Information Systems Architecture oResolve impacts across the Architecture Landscape

*1C: Develop the Target Data Architecture that enables the Business Architecture and the Architecture Vision
*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 References: 1: The TOGAF Architecture Development Method

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.

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:

The illustration shows the relationship between the Enterprise Continuum, the Architecture Continuum, and the Solutions Continuum, which are key concepts in the TOGAF framework. The Enterprise 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:

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. Iteration enables 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.
