Based on the web search results, architecture partitioning is a technique that divides the Enterprise Architecture into smaller and manageable segments or groups, based on various classification criteria, such as subject matter, time, maturity, volatility, etc.12 Architecture partitioning is used to simplify the development and management of the Enterprise Architecture, by reducing complexity, improving governance, enhancing reusability, and increasing alignment and agility12. Therefore, the statement that partitions are used to simplify the management of the Enterprise Architecture is correct.

The other statements are incorrect because:

•Partitions are not equivalent to architecture levels. Architecture levels are different layers of abstraction that describe the Enterprise Architecture from different perspectives, such as strategic, segment, and capability3. Partitions are subsets of architectures that are defined within or across the levels, based on specific criteria1.

•Partitions do not necessarily reflect the organization’s structure. The organization’s structure is one possible criterion for partitioning the architecture, but it is not the only one. Other criteria, such as business function, product, service, geography, etc., can also be used to partition the architecture12.

•Partitions are not defined and assigned to agile Enterprise Architecture teams. Agile Enterprise Architecture is an approach that applies agile principles and practices to the architecture work, such as iterative development, frequent feedback, adaptive planning, and continuous delivery4. Partitions are not a specific feature of agile Enterprise Architecture, but a general technique that can be applied to any architecture method or framework, including TOGAF12.

According to the TOGAF Standard, 10th Edition, a transformation readiness assessment is a technique that evaluates the preparedness of the organization to undergo a change, and identifies the actions needed to increase the likelihood of a successful outcome. A transformation readiness assessment can be conducted in Phase E: Opportunities and Solutions, and the actions resulting from it can be dealt with in Phase F: Migration Planning 1. In Phase E, the transformation readiness assessment can help to identify the major implementation challenges and risks, and to define the critical success factors and key performance indicators for the architecture project. In Phase F, the actions resulting from the transformation readiness assessment can help to develop a detailed and realistic migration plan, and to address the gaps, issues, and dependencies that may affect the transition to the target architecture 1.

Architecture Principles are general rules and guidelines that inform and support the way in which an organization sets about fulfilling its mission. They reflect a level of consensus among the various elements of the enterprise, and form the basis for making future IT decisions. One of the purposes of Architecture Principles is to establish a common understanding of how to control the business in pursuit of strategic objectives, by providing a framework for evaluating and agreeing on the changes that affect the enterprise’s architecture3 References: 3: The TOGAF Standard, Version 9.2, Part III: ADM Guidelines and Techniques, Chapter 23: Architecture Principles : The TOGAF Standard, Version 9.2, Part IV: Architecture Content Framework, Chapter 31: Architecture Principles

According to the TOGAF Standard, Version 9.2, the ADM phases and their objectives are as follows1:

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.

Requirements Management: To manage the architecture requirements throughout the ADM cycle, and to ensure alignment with the business requirements.

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

Objective 1: Ensure that the business value and cost of work packages and transition architectures is understood by key stakeholders. This objective is achieved in Phase H: Architecture Change Management, where the value realization and cost-benefit analysis of the architecture are performed2.

Objective 2: Ensure conformance with the Target Architecture by implementation projects. This objective is achieved in Phase F: Migration Planning, where the conformance requirements and criteria for the implementation projects are defined3.

Objective 3: Ensure that the architecture development cycle is maintained. This objective is achieved in Phase F: Migration Planning, where the architecture roadmap and iteration cycle are maintained3.

Objective 4: Ensure that the Architecture Governance Framework is executed. This objective is achieved in Phase G: Implementation Governance, where the architecture governance processes and procedures are applied to the implementation projects4.
