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.

Statements 1 and 3 highlight the value and necessity for Architecture Governance to be adopted within organizations. Architecture Governance is the practice and orientation by which Enterprise Architectures and other architectures are managed and controlled at an enterprise-wide level12. It ensures that architectural decisions are aligned with the organization's strategy, objectives, and standards. Architecture Governance also involves establishing and maintaining processes, decision-making, and mechanisms to avoid or minimize potential conflicts of interest, such as between different stakeholders, business units, or projects34. Moreover, Architecture Governance requires transparency and accountability for all actions implemented and their decision support, so that they can be inspected and evaluated by authorized parties, such as auditors, regulators, or customers5 .

* 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.

The TOGAF standard divides Enterprise Architecture into four primary architecture domains:
business, data, application, and technology.
These domains represent different aspects of an enterprise and how they relate to each other.
The business domain defines the business strategy, governance, organization, and key business processes.
The data domain describes the structure of the logical and physical data assets and data management resources.
The application domain provides a blueprint for the individual applications to be deployed, their interactions, and their relationships to the core business processes.
The technology domain describes the logical software and hardware capabilities that are required to support the deployment of business, data, and application services.
Other domains, such as motivation, security, or governance, may span across these four primary domains.

An EA Capability is the ability of an organization to perform enterprise architecture effectively and efficiently. It involves establishing and maintaining the appropriate organization structures, roles, responsibilities, skills, processes, tools, and governance mechanisms to support the development and use of enterprise architecture. An EA Capability enables the organization to align its business and IT strategies, deliver value from its investments, manage change and complexity, and improve its performance and agility12 Reference: 1: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 44: Introduction 2: The TOGAF Standard, Version 9.2, Part VI: Architecture Capability Framework, Chapter 45: Establishing and Maintaining an Enterprise Architecture Capability
