Enterprise Architecture Execution and Monitoring

01.Introduction

At Migration planning phase, We Discuss how to move from the existing as-is-architecture to the to-be model

Use the Capabilities Gap analysis to :

2.Migration Scope

• • Finalize Capabilities Gap analysis

  • Formulate Final architecture roadmap

  • build acquire and develop data architecture 

  • Acquire and develop application architecture 

  • develop technology architecture 

3.Change Development

• • Maintain existing process  

  • Maintain existing policies

  • Maintain existing organization structure

  • Create training programs

4.Projects Management

• • Create Migration projects portfolio

  • Issue RFPs for the migration

  • Create Management approach

  • Create staged upgrade model and management approach

  • Resources and budget planning

  • Communication plan

1.Introduction

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:

2.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

3. 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

4. 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.

5. 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.

6. 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.

7. Architecture Review Board (ARB)

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

8.Core Architecure Principles reforming:

• Use in governance

• Upgrade when change
