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.
