Understand the roles of stakeholders, views, and viewpoints in architectural design
Understanding the roles of stakeholders, views, and viewpoints is essential in enterprise architecture (EA), especially within the TOGAF® Standard, 10th Edition framework. These concepts ensure that architectural designs are aligned with the needs of different individuals and groups within an organization.
Let’s break them down:
👥 Stakeholders
🔍 Definition:
A stakeholder is any individual, team, or organization that has an interest in, or will be affected by, the outcome of the enterprise architecture.
🎯 Purpose:
To ensure that the architecture addresses the concerns , needs , and expectations of all relevant parties involved.
📋 Common Stakeholder Types in EA:
| Stakeholder | Role / Concern |
|---|---|
| C-Level Executives (CEO, CIO) | Strategic alignment, ROI, risk management |
| Business Managers | Business capabilities, process efficiency |
| IT Architects | Technical consistency, integration, scalability |
| Project Managers | Delivery timelines, resource allocation |
| End Users | Usability, performance, accessibility |
| Regulatory Bodies | Compliance, data privacy, governance |
| Vendors / Partners | Interoperability, integration points |
✅ Best Practice:
Use a Stakeholder Map to identify and prioritize stakeholders early in the Architecture Development Method (ADM) — particularly in Phase A: Architecture Vision .
👀 Views
🔍 Definition:
A view is a representation of a system from the perspective of a related set of concerns. It provides a tailored depiction of the architecture relevant to a particular stakeholder.
🎯 Purpose:
To communicate specific aspects of the architecture that address the unique concerns of a stakeholder or group.
🧩 Example Views:
| View Type | Description | Audience |
|---|---|---|
| Business Process View | Shows workflows and business functions | Business Analysts, Managers |
| Data Entity-Relationship View | Depicts how data entities relate | Data Architects |
| Application Interaction View | Shows how apps communicate | IT Teams, Integration Architects |
| Technology Stack View | Illustrates hardware/software infrastructure | Infrastructure Teams |
✨ Note:
Each view is derived from one or more architecture domains (Business, Data, Application, Technology) and should be clearly defined using viewpoints .
🎨 Viewpoints
🔍 Definition:
A viewpoint is a specification of the conventions for constructing and using a view. It defines what kind of information appears in the view and how it is represented.
🎯 Purpose:
To provide a template or pattern for creating consistent, meaningful views that address specific stakeholder concerns.
🛠️ Components of a Viewpoint:
| Component | Description |
|---|---|
| Concerns | The questions or issues the viewpoint addresses |
| Stakeholders | Who uses this type of view |
| Modeling Notation | Diagram types or symbols used (e.g., UML, ArchiMate) |
| Content Guidance | What elements to include in the view |
| Constraints & Assumptions | Rules or limitations guiding the view’s creation |
📚 Example Viewpoints:
| Viewpoint | Concern | Stakeholder | Output View |
|---|---|---|---|
| Business Footprint Diagram | How business services map to locations | Business Executives | Business Location View |
| Use Case Viewpoint | Functional requirements of a system | Developers, Analysts | Use Case Diagram |
| Logical Data Model Viewpoint | Structure of data entities | Data Architects | ER Diagram |
| Infrastructure Landscape Viewpoint | Physical servers, networks, cloud platforms | IT Operations | Infrastructure Diagram |
🔁 Relationship Between Stakeholders, Viewpoints, and Views
[ Stakeholders ]

🧩 2. Architecture Building Blocks (ABBs) vs. Solution Building Blocks (SBBs)
These are reusable components used throughout the ADM process.
🔲 Architecture Building Block (ABB)
- Abstract : Defines the required capability without specifying implementation.
- Used in early phases (e.g., visioning, planning).
- Example: “User Authentication Service”
▶️ Solution Building Block (SBB)
- Concrete : Implements an ABB using specific technologies or products.
- Used in later phases (e.g., migration, implementation).
- Example: “Okta Identity Cloud” or “Microsoft Azure AD”
💡 ABB → SBB Relationship : One ABB can be implemented by multiple SBBs depending on context and technology choices.
📄 3. Common Architecture Artifacts
Artifacts provide detailed descriptions of the architecture. They come in three main types:
🗂️ Catalogs
- Lists of architecture elements
- Examples:
- Application Catalog : All applications in use
- Data Entity Catalog : Business data entities
- Technology Component Catalog : Hardware/software inventory
🔗 Matrices
- Show relationships between elements
- Examples:
- Actor/Application Matrix : Who uses which application?
- Data/Function Matrix : What data supports each function?
- Interface Matrix : How do applications interact?
🖼️ Diagrams
- Visual representations of architecture components
- Examples:
- Business Process Diagram : End-to-end workflows
- Application Interaction Diagram : System integrations
- Technology Stack Diagram : Infrastructure layers
- Use Case Diagram : Functional system behavior
🔄 Integration with the ADM Cycle
Here’s how these components are typically used in each phase of the ADM :
| ADM Phase | Key Deliverables | Key Artifacts & Building Blocks |
|---|---|---|
| Preliminary | Architecture Principles, Governance Framework | Foundation Architectures, Standards Information Base |
| A – Vision | Architecture Vision, Communications Plan | Stakeholder Map, Business Scenarios |
| B – Business | Business Architecture Description | Business Function Catalog, Process Diagrams, Actor/Application Matrix |
| C1 – Data | Data Architecture Description | Data Entity Catalog, Data Flow Diagrams, Data/Function Matrix |
| C2 – Application | Application Architecture Description | Application Catalog, Interface Matrix, Application Interaction Diagram |
| D – Technology | Technology Architecture Description | Technology Component Catalog, Technology Stack Diagram |
| E – Opportunities | Work Packages, Solution Building Blocks | Gap Analysis Reports, Candidate Roadmaps |
| F – Migration | Implementation & Migration Plan | Project Plans, Cost/Benefit Analysis, Risk Assessments |
| G – Governance | Architecture Contract, Compliance Assessment | Governance Logs, Audit Reports |
| H – Change Management | Change Request Log, Updated Repository | Updated Views, Revised Building Blocks |
✅ Best Practices for Using Deliverables, Artifacts, and Building Blocks
- Tailor to Stakeholders : Use views and viewpoints to present relevant content.
- Leverage Reuse : Start with Foundation and Common Systems Architectures from the Enterprise Continuum.
- Maintain Consistency : Ensure all artifacts align with the Architecture Metamodel and Content Framework.
- Document Thoroughly : Store deliverables and artifacts in the Architecture Repository.
- Iterate and Refine : Update deliverables as more information becomes available during the ADM cycle.

| Type | Purpose | Examples |
|---|---|---|
| Deliverables | Formal documentation shared with stakeholders | Architecture Vision, ADD, IMP, Contracts |
| Artifacts | Models, diagrams, and structured data | Catalogs, Matrices, Diagrams |
| Building Blocks | Reusable components | ABBs (abstract), SBBs (concrete) |
