Business principles business goals, and business drivers provide context for architecture work, by describing the needs and ways of working employed by the enterprise. They define what the enterprise wants to achieve, how it wants to operate, and what factors influence its decisions and actions. Reference: The TOGAF Standard | The Open Group Website, Section 3.2 Preliminary Phase.

The phase of the ADM labeled as item 1 is Phase F: Migration Planning. This phase conducts implementation planning for the architecture defined in previous phases by creating an Architecture Roadmap and a detailed Implementation and Migration Plan. This phase also identifies and groups major work packages, transition architectures, projects, and dependencies. Reference: https://pubs.opengroup.org/architecture/togaf9-doc/arch/chap19.html

The objective of the ADM Implementation Governance Phase is to provide an architectural oversight of the implementation and to ensure conformance for the target architecture. This phase involves establishing procedures and processes to monitor and control the implementation projects and to verify that they comply with the defined architecture. Reference: The TOGAF Standard | The Open Group Website, Section 3.2.7 Phase G: Implementation Governance.

The purpose of Enterprise Architecture is to guide effective change by providing a coherent and consistent view of the enterprise's current and future state, as well as the roadmap and principles for achieving it. Enterprise Architecture helps to align business and IT strategies, optimize resources and investments, reduce complexity and risks, enhance agility and innovation, and deliver value to stakeholders. Reference: The TOGAF Standard | The Open Group Website, Section 1.3 Executive Overview.

Ensuring compliance with internal and external standards and regulatory obligations is one of the activities included as part of Architecture Governance. Architecture Governance is the practice and orientation by which enterprise architectures and other architectures are managed and controlled at an enterprise-wide level. It involves establishing processes, roles, responsibilities, policies, and standards to ensure that architectures are aligned with the enterprise's strategy and objectives, and meet the quality and performance requirements.
