Implementation & Migration Viewpoints: Project and Migration Roadmaps
Implementation and Migration viewpoints are specifically designed for modeling the management of architecture change, the transition from baseline to target states, and the complex relationships between programs and projects. These viewpoints support critical phases of the TOGAF ADM, including Phase E (Opportunities and Solutions), Phase F (Migration Planning), and Phase G (Implementation Governance). By utilizing specialized elements such as Work Packages, Deliverables, Plateaus, and Gaps, these views allow architects to communicate implementation roadmaps to stakeholders like operational managers and shareholders.
1. The Project Viewpoint
The Project viewpoint focuses on the management of architectural change, modeling the specific projects governed and delivered during a migration. It is used to show the scope of a project and the results it produces to realize architectural goals.
- Key Elements: Work Package, Deliverable, Implementation Event, Goal, Business Actor, and Business Role.
- Practical Example: To organize a technical upgrade, a project manager can use the AI Chatbot with the prompt: “Generate an ArchiMate diagram of the Project viewpoint depicting the timelines, milestones, and dependencies of a hospital information system upgrade project”. The resulting model will visualize the bundle of tasks (Work Packages) and the outputs (Deliverables), such as a new application module.
2. The Migration Viewpoint
The Migration viewpoint entails models and concepts used for specifying the transition from an existing (baseline) architecture to a desired (target) architecture. It provides a historical and future-looking perspective on the evolution of models.
- Key Elements: Plateau and Gap.
- Practical Example: An architect can prompt the AI Diagram Generator: “Generate an ArchiMate diagram of the Migration viewpoint illustrating the phased transition from on-premise ERP to a cloud-based solution for a manufacturing company”. The AI will draft a model showing stable intermediate states (Plateaus) and the specific missing capabilities (Gaps) that need to be addressed at each stage.
3. The Implementation and Migration Viewpoint
This comprehensive viewpoint relates programs and projects to the specific parts of the architecture they implement. It allows architects to model the scope of activities in terms of the plateaus they realize or the individual architecture elements (Business, Application, or Technology) they affect.
- Key Elements: Goal, Requirement, Plateau, Gap, Work Package, Deliverable, and Core Elements.
- Practical Example: For a large-scale modernization effort, an architect might use the prompt: “Generate an ArchiMate diagram of the Implementation and Migration viewpoint showing the rollout plan for migrating a legacy payroll system to a cloud platform”. This produces a multi-layer view that traces how project work packages realize requirements across different technology nodes and business processes.
Summary of Implementation & Migration Roadmaps
| Viewpoint | Primary Purpose | Stakeholder Concerns |
|---|---|---|
| Project | Deciding, Informing | Project delivery, architecture vision, and goal achievement. |
| Migration | Designing, Deciding | Transition states, gap analysis, and model history. |
| Implementation & Migration | Deciding, Informing | Project scope, cross-layer impact, and implementation policies. |
By using Visual Paradigm’s certified ArchiMate 3.2 toolset, architects can automatically generate these roadmaps from simple text prompts, ensuring that complex transition architecture states are clearly communicated and syntactically correct.
