Enterprise Architecture Execution and Monitoring

09-Implementation Governance

In the context of the TOGAF Architecture Development Method (ADM), Implementation Governance ensures that the architecture is implemented according to the established design and meets enterprise goals. Key components of Implementation Governance include:

1. Architecture Governance Framework

• These formal agreements between stakeholders (e.g., development teams and business units) define architecture deliverables, standards, principles, and compliance requirements. They are foundational to align implementations with architecture.

• A formal governance structure that involves stakeholders across IT, business, and project management. It establishes accountability, roles, and decision-making criteria for architecture compliance.

• Management Approach : Agile/Big Bang

• RACI Matrix

2. Change Management Processes

• A structured approach for managing changes in scope, requirements, or implementation details. This ensures that changes align with strategic objectives and do not compromise architecture integrity.

• CCB: Change control board formulation

• Approval Process: What is the approval process for the change

3. Key Performance Indicators (KPIs) and Metrics

• Metrics to evaluate the success of the architecture implementation, ensuring it delivers value to the business and aligns with performance expectations set out in the architecture vision.

4. Risk and Issue Management

• Identifying, analyzing, and managing risks related to the architecture implementation. This also involves mitigation plans for issues that may impact project outcomes or compliance.

5. Compliance Assessments

• Regular checks to confirm that implementations align with the defined architecture standards and specifications. This may include architecture reviews and quality assurance checkpoints to detect deviations early.

6. Architecture Review Board (ARB)

• A governance body responsible for evaluating architecture compliance, addressing issues, and providing final approvals on architecture changes and implementations.

7. Core Architecure Principles reforming:

• Use in governance

• Upgrade when change

10-Change Management

What is?

In the TOGAF Architecture Development Method (ADM), change management is crucial to ensure alignment with the enterprise's evolving needs. 

Key Activities

Here are the key activities in ADM change management:

1. Change Request and Approval Process

   • Documenting and validating change requests through formal channels. This includes categorizing changes based on their impact on architecture components and securing necessary approvals.

2. Impact Assessment and Analysis

   • Analyzing the implications of proposed changes on the current architecture, including impacts on systems, business processes, and data. This step helps to understand dependencies and scope out potential disruptions.

3. Architecture Requirements Management

   • Ensuring that all architecture changes align with existing requirements or modifying requirements as necessary to reflect new business needs, facilitating consistency throughout the architecture lifecycle.

4. Updating the Architecture Repository

   • Recording approved changes in the Architecture Repository, including documentation, models, and views. This ensures that all stakeholders have access to updated, accurate information.

5. Stakeholder Engagement and Communication

   • Keeping stakeholders informed of planned changes, timelines, and benefits through structured communication channels, thereby minimizing resistance and promoting buy-in.

6. Alignment with Strategic Objectives

   • Validating that all changes align with the enterprise's strategic goals. This involves ensuring that any adjustments to the architecture support the overall mission and vision of the organization.

7. Risk and Impact Mitigation Planning

   • Identifying risks associated with architecture changes and developing mitigation strategies to prevent disruption to business operations or other architectural domains.

8. Compliance and Quality Assurance

   • Conducting reviews and assessments to ensure that the change adheres to architecture standards, guidelines, and principles. This step includes checking for compliance with industry regulations where applicable.

9. Architecture Governance Board Review

   • Presenting changes to an Architecture Governance Board or similar body for oversight, ensuring that modifications are in line with enterprise-wide architecture policies.

10. Post-Implementation Evaluation

    • Assessing the effectiveness of the change after implementation through feedback loops, performance monitoring, and lessons-learned reviews. This supports continuous improvement in the ADM process.
