Step-by-Step Tutorial: How to Build a Complete Enterprise Architecture Using TOGAF ADM, ArchiMate, C4, and Visual Paradigm (with AI Support)

In a world that’s constantly changing, one thing remains true: curiosity drives progress. Whether we’re exploring new ideas, uncovering hidden truths, or simply trying to understand the world around us, the journey begins with a single step—often, a thoughtful introduction.

This is more than just an opening; it’s a gateway. A moment to pause, reflect, and set the stage for what’s to come. So let’s begin—not with answers, but with questions. Not with certainty, but with possibility.

Because every great story, every powerful idea, starts with an intro.

Perfect for Enterprise Architects, Solution Architects, and DevOps Teams
🛠️ Tools Used: Visual Paradigm (Free Trial Available), TOGAF ADM, ArchiMate 3.2, C4 Model
📌 Goal: Build a full enterprise architecture for an e-commerce system—from business vision to code-ready diagrams—with AI-powered automation and traceability.


✅ Step 0: Set Up Your Environment

🔧 What You Need:

  • Visual Paradigm (Download from www.visual-paradigm.com)

  • Free Trial available (no credit card required)

  • Internet connection

  • Optional: GitHub account (for code integration)

📌 Steps:

  1. Go to https://www.visual-paradigm.com

  2. Click “Download” → Choose Visual Paradigm Community Edition (free).

  3. Install and launch the application.

  4. On startup, select “Create New Project” → Choose “Enterprise Architecture” template.

  5. Name your project: “RetailX E-Commerce Migration”

✅ You now have a fully configured TOGAF ADM workspace with ArchiMate and C4 support.


🟦 Step 1: Define the Architecture Vision (TOGAF Phase A)

🎯 Goal: Model business goals, drivers, and high-level system context.

🛠️ Steps:

  1. In the Project Explorer, right-click “Architecture Vision” → Select “Create New Diagram” → Choose “ArchiMate Motivation”.

  2. Add:

    • Business GoalReduce checkout time to under 3 seconds

    • Business DriverCustomer experience improvement

    • CapabilityFast Order Processing

  3. Click “AI Assistant” (top-right) → Type:

    “Generate a high-level context diagram for an e-commerce system serving customers with payment and inventory integration.”

  4. Visual Paradigm auto-generates:

    • C4 Level 1 (Context) diagram showing:

      • Person: Customer

      • Software System: E-Commerce Platform

      • External Systems: Payment Gateway, Inventory System

    • ArchiMate Motivation Diagram showing goal → driver → capability.

✅ Pro Tip: Use the “Sync” button to link ArchiMate elements to C4 diagrams automatically.


🟨 Step 2: Model Business Architecture (TOGAF Phase B)

🎯 Goal: Break down business processes and services.

🛠️ Steps:

  1. Go to “Business Architecture” → Create a new ArchiMate Business Process Diagram.

  2. Add:

    • Business Actor: Customer

    • Business Process: Place Order

    • Business Service: Order Validation

    • Data Object: Order Details

  3. Use drag-and-drop to connect:

    • Customer → Place Order

    • Place Order → Order Validation

    • Order Validation → Order Details (data flow)

  4. Open AI Assistant → Type:

    “Suggest improvements to the ‘Place Order’ process and identify missing components.”

  5. AI responds:

    • Suggests adding “Inventory Check” and “Payment Processing” services.

    • Recommends splitting the process into sub-processes.

  6. Update your diagram accordingly.

✅ Now your business process is complete, traceable, and AI-optimized.


🟥 Step 3: Model Information Systems Architecture (TOGAF Phase C)

🎯 Goal: Model application components, data flows, and integration.

🛠️ Steps:

  1. Go to “Information Systems Architecture” → Create ArchiMate Application Landscape.

  2. Add:

    • Application Component: Order Service

    • Application Component: Payment Service

    • Application Component: Inventory Service

    • Data Object: Order Data

  3. Add relationships:

    • Realization: Order Service → Order Validation (shows how it’s supported)

    • Data Flow: Order Service → Payment Service

    • Dependency: Payment Service → Inventory Service

  4. Use AI Assistant → Type:

    “Generate a C4 Level 2 (Container) diagram based on these components.”

  5. Visual Paradigm auto-generates:

    • Container Diagram showing:

      • API Gateway (container)

      • Order Microservice (container)

      • Payment Service (container)

      • Database (PostgreSQL) (container)

    • Interaction arrows: HTTPS, REST, gRPC

✅ Your architecture now spans enterprise modeling (ArchiMate) and technical clarity (C4).


🟩 Step 4: Model Technology Architecture (TOGAF Phase D)

🎯 Goal: Define infrastructure, deployment, and cloud environment.

🛠️ Steps:

  1. Go to “Technology Architecture” → Create ArchiMate Technology View.

  2. Add:

    • Technology Node: AWS EC2 (for Order Microservice)

    • Technology Node: Kubernetes Cluster (for deployment)

    • Technology Node: AWS S3 (for storage)

    • Network: Internal Network

  3. Connect with:

    • Deployment: EC2 → Kubernetes

    • Data Flow: S3 → EC2

  4. Use AI Assistant → Type:

    “Suggest cloud deployment patterns for microservices and security best practices.”

  5. AI recommends:

    • Auto-scaling groups

    • IAM roles

    • Load balancer

    • VPC segmentation

  6. Use the “Generate Deployment Diagram button → Creates C4 Level 2 Deployment Diagram.

✅ Now you have a cloud-ready architecture with real infrastructure mapping.


🟪 Step 5: Analyze Opportunities & Solutions (TOGAF Phase E)

🎯 Goal: Compare current vs. target architecture and identify gaps.

🛠️ Steps:

  1. Go to “Opportunities and Solutions” → Create ArchiMate Gap Analysis View.

  2. Use AI Assistant → Type:

    “Compare current monolith architecture with target microservices architecture. Identify gaps and suggest migration paths.”

  3. Visual Paradigm generates:

    • Side-by-side comparison of current vs. target

    • Gap Analysis Table:

      Component Current Target Gap
      Order Service Monolith Microservice ✅ New
      Inventory Check In-app Separate service ❌ Missing
      Payment Gateway Direct API-based ⚠️ Needs refactoring
  4. AI suggests:

    • “Decompose monolith into 3 services: Order, Payment, Inventory.”

    • “Start with Order Service migration.”

✅ You now have a clear, AI-backed migration strategy.


🟫 Step 6: Plan Migration (TOGAF Phase F)

🎯 Goal: Create a migration roadmap with risks and dependencies.

🛠️ Steps:

  1. Go to “Migration Planning” → Create Migration Plan.

  2. Use AI Assistant → Type:

    “Create a 6-month migration plan with phases, risks, and dependencies.”

  3. AI generates:

    • Gantt Chart with:

      • Month 1–2: Refactor Order Service

      • Month 3–4: Deploy Payment Service

      • Month 5–6: Integrate Inventory Service

    • Risk Matrix:

      • High Risk: Data migration

      • Medium Risk: API compatibility

    • Dependency Graph: Shows which services must be ready first.

✅ Share the plan with stakeholders via PDF export or HTML report.


🟪 Step 7: Implement Governance (TOGAF Phase G)

🎯 Goal: Enforce architecture compliance with code.

🛠️ Steps:

  1. Go to “Implementation Governance” → Create Governance View.

  2. Use AI Assistant → Type:

    “Set up compliance rules: All services must use API Gateway and not access DB directly.”

  3. Visual Paradigm creates:

    • Architecture Rule: “No direct DB access from API”

    • CI/CD Integration: Connect to GitHub (via plugin)

  4. When a developer pushes code:

    • Visual Paradigm scans the code

    • Flags violations (e.g., db.query() in API)

    • Blocks PRs if rule is broken

✅ Architecture becomes enforced, not ignored.


🟦 Step 8: Manage Changes (TOGAF Phase H)

🎯 Goal: Track changes and update architecture.

🛠️ Steps:

  1. Go to “Architecture Change Management” → Use “Change Impact Analysis”.

  2. Make a change: Rename “Order Service” → “Order Management Service”

  3. Click “Analyze Impact” → AI identifies:

    • Affected diagrams: C4 Level 2, ArchiMate Application Landscape

    • Impacted services: Payment Service, Inventory Service

    • Code files: OrderController.javaorder-service.yml

  4. Use “Auto-Update” to regenerate all affected diagrams.

✅ Changes are traceable, safe, and consistent.


✅ Final Output: Your Complete Architecture Is Ready

You now have:

Artifact Format Source
Business Goal & Context ArchiMate + C4 Level 1 Phase A
Business Process ArchiMate Phase B
Application & Data Model ArchiMate Phase C
Deployment & Infrastructure C4 Level 2 + ArchiMate Phase D
Migration Plan Gantt + Risk Matrix Phase F
Governance Rules Code-linked Phase G
Change Impact Report AI-analyzed Phase H

🎉 All in one platform. All connected. All traceable.
