The illustration shows an architecture development cycle based on the TOGAF ADM (Architecture Development Method), which is a method for developing and managing an enterprise architecture1.

The ADM consists of nine phases, each with a specific purpose and output. The phases are1:

Preliminary Phase: To prepare and initiate the architecture development cycle, including defining the architecture framework, principles, and governance.

Phase A: Architecture Vision: To define the scope, vision, and stakeholders of the architecture initiative, and to obtain approval to proceed.

Phase B: Business Architecture: To describe the baseline and target business architecture, and to identify the gaps between them.

Phase C: Information Systems Architectures: To describe the baseline and target data and application architectures, and to identify the gaps between them.

Phase D: Technology Architecture: To describe the baseline and target technology architecture, and to identify the gaps between them.

Phase E: Opportunities and Solutions: To identify and evaluate the opportunities and solutions for implementing the target architecture, and to define the work packages and transition architectures.

Phase F: Migration Planning: To finalize the implementation and migration plan, and to ensure alignment with the enterprise portfolio and project management.

Phase G: Implementation Governance: To provide architecture oversight and guidance for the implementation projects, and to manage any architecture change requests.

Phase H: Architecture Change Management: To monitor the changes in the business and technology environment, and to assess the impact and performance of the architecture.

In addition to these phases, there is a central process called Requirements Management, which is labeled as item 1 in the illustration. This process operates throughout the ADM cycle, and its purpose is to manage the architecture requirements throughout the architecture development, ensuring that they are aligned with the business requirements and the stakeholder concerns2.

Therefore, the description that matches the phase of the ADM labeled as item 1 is C. Operates the process of managing architecture requirements.

Gap Analysis is a technique that compares the Baseline Architecture and the Target Architecture to identify the differences and gaps between them. The purpose of this technique is to determine the changes and additions that are required to achieve the desired future state of the architecture. One of the main aspects of Gap Analysis is to identify the functions that are missing or overlapping in the current and future architectures, and to plan how to address them. This helps to ensure that the architecture is complete, consistent, and aligned with the business objectives and requirements3

The Architecture Landscape is divided into levels known as Segment Strategic and Capability Architectures. These levels correspond to different scopes and purposes of architectures within an enterprise. Segment Architectures are architectures that address specific business units, functions, or processes within an enterprise. Strategic Architectures are architectures that provide a high-level view of the enterprise’s vision, goals, and direction. Capability Architectures are architectures that address specific business capabilities or services that span multiple segments or domains.

EA applies architecture principles and practices to analyze, design, plan, and implement enterprise analysis that supports digital transformation, IT growth, and the modernization of IT2. EA also helps organizations improve the efficiency, timeliness, and reliability of business information, as well as the alignment, agility, and adaptability of the architecture to the changing needs and requirements3. Therefore, the best summary of the purpose of EA is to guide effective change.
