Introduction
Welcome to the world of TOGAF Architecture Development Method (ADM) Phase G: Implementation Governance. In this crucial phase, the strategic visions and meticulous planning from previous stages begin to materialize. Phase G serves as the vigilant overseer, ensuring that the architectural designs are not just ideas on paper but seamlessly integrate into the operational fabric of the enterprise.
Let’s delve into the intricacies of Phase G, exploring its objectives, steps, and the orchestrated dance between implementation and governance.
Overview:
The Implementation Governance phase (Phase G) in TOGAF aims to provide oversight and ensure the successful implementation of the architectural vision. This involves offering recommendations for individual projects, constructing an Architecture Contract, performing governance functions, and ensuring adherence to the defined architecture. The approach involves establishing an implementation program and a phased deployment schedule based on business priorities and the Architecture Roadmap.
Objectives:
- Recommendations for Each Project:
- Action: Review outputs of migration planning.
- Objective: Identify priorities, issues, and building blocks.
- Result: Produce recommendations and perform gap analysis related to Solution Building Blocks.
- Architecture Contract Establishment:
- Action: Connect implementation and architecture organizations.
- Objective: Use the Architecture Contract to align activities.
- Result: Ensure coordinated efforts between implementation and architecture teams.
- Deployment Program Development:
- Action: Establish an implementation program.
- Objective: Enable delivery of transition architectures agreed upon in the Migration Planning phase.
- Result: Develop a phased deployment schedule based on business priorities and the Architecture Roadmap.
Inputs to Phase G:
- Architecture Reference Materials
- Request for Architecture Work
- Capacity Assessment
- Organizational Model for Enterprise Architecture
- Tailored Architecture Framework
- Statement of Architecture Work
- Architecture Vision
- Architecture Repository
- Architecture Definition Document
- Architecture Requirements Specification
- Architecture Roadmap
- Transition Architectures
- Implementation Governance Model
- Architecture Contract
- Implementation and Migration Plan
Steps in Phase G:
- Confirming Scope and Priorities for Deployment:
- Action: Review migration planning outputs.
- Outcome: Recommendations, identification of priorities, issues, and building blocks, gap analysis related to Solution Building Blocks.
- Identifying Deployment Resources and Skills:
- Action: Identify required system development methods.
- Outcome: Ensure methods allow feedback to the architecture team on designs.
- Guiding Development of Solutions Deployment:
- Action: Formulate recommendations, document the Architecture Contract, and update documentation or repositories.
- Outcome: Updated documentation, Architecture Contract, and recommendations for projects.
- Performing Compliance Reviews:
- Action: Review governance and compliance for each building block.
- Outcome: Post-development reviews, closure of the development portion of deployment projects.
- Implementing Business and IT Operations:
- Action: Carry out deployment projects.
- Outcome: Published Baseline Architectures, updated repositories.
- Performing Post-Implementation Review:
- Action: Conduct reviews after implementation.
- Outcome: Published reviews, closure of completed projects.
Expected Outputs:
- Architecture Contract
- Compliance Assessments
- Change Requests
- Architecture-Compliant Solutions

This tabular summary provides a quick overview of the key aspects, objectives, approach, inputs, steps, and expected outputs of the TOGAF ADM Phase G: Implementation Governance.
Conclusion
TOGAF ADM Phase G is the bridge between envisioning an architectural future and realizing it in the present. With a clear focus on providing recommendations, constructing a robust Architecture Contract, and performing governance functions, this phase is the linchpin in the successful deployment of architectural solutions. From confirming scope and priorities to performing post-implementation reviews, Phase G meticulously guides the implementation journey, ensuring not only compliance with the defined architecture but the actualization of a resilient and adaptable enterprise. The outputs, ranging from the tangible Architecture Contract to compliance assessments, are the tangible fruits of a well-executed Implementation Governance phase.
The Implementation Governance phase ensures a smooth transition from planning to implementation by providing oversight, aligning activities through the Architecture Contract, and ensuring compliance with the defined architecture. The outputs include essential documents and assessments that contribute to the success of the deployment projects.
