* 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:
oPreliminary Phase: To prepare and initiate the architecture development cycle, including defining the architecture framework, principles, and governance.
oPhase A: Architecture Vision: To define the scope, vision, and stakeholders of the architecture initiative, and to obtain approval to proceed.
oPhase B: Business Architecture: To describe the baseline and target business architecture, and to identify the gaps between them.
oPhase C: Information Systems Architectures: To describe the baseline and target data and application architectures, and to identify the gaps between them.
oPhase D: Technology Architecture: To describe the baseline and target technology architecture, and to identify the gaps between them.
oPhase 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.
oPhase F: Migration Planning: To finalize the implementation and migration plan, and to ensure alignment with the enterprise portfolio and project management.
oPhase G: Implementation Governance: To provide architecture oversight and guidance for the implementation projects, and to manage any architecture change requests.
oPhase 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:
oObjective 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.
oObjective 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.
oObjective 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.
oObjective 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.
