The Open Group Updated OGEA-101 Exam Questions and Answers by fergus

The purpose of the Gap Analysis technique is similar to the previous question, but with a focus on the Target Architecture. The technique helps to identify the items that are not included or specified in the Target Architecture, such as capabilities, services, components, standards, or technologies. These items may be essential for achieving the vision and goals of the enterprise, or for addressing the stakeholder concerns and requirements. By identifying the items omitted from the Target Architecture, the technique helps to ensure that the architecture is comprehensive, feasible, and realistic.

The planning horizon, depth, and breadth of an Architecture Project, along with the contents of the EA Repository, are typically framed by Strategy, Portfolio, Segment, and End-to-end Target Architecture. The 'Segment' refers to a part of the organization, typically addressed in a Segment Architecture, while 'End-to-end Target Architecture' encompasses the complete view of the planned architecture across the entire organization.

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 objectives listed in the question correspond to the objectives of different phases of 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.

Based on the above definitions, we can match each objective with the corresponding phase as follows:

Objective 1: Develop the Target Data Architecture that enables the Business Architecture and the Architecture Vision. This objective is achieved in Phase C: Information Systems Architectures, where the data architecture is defined as a subset of the information systems architecture2.

Objective 2: Develop the Target Business Architecture that describes how the enterprise needs to operate to achieve the business goals. This objective is achieved in Phase B: Business Architecture, where the business architecture is defined as a subset of the enterprise architecture3.

Objective 3: Develop a high-level aspirational vision of the capabilities and business value to be delivered as a result of the proposed Enterprise Architecture. This objective is achieved in Phase A: Architecture Vision, where the architecture vision is defined as a high-level description of the target architecture and its benefits4.

Objective 4: Develop the Target Application Architecture that enables the Business Architecture and the Architecture Vision, in a way that addresses the Statement of Architecture Work and stakeholder concerns. This objective is achieved in Phase C: Information Systems Architectures, where the application architecture is defined as a subset of the information systems architecture2.
