# 🏢 How-To: Large Team Scaling

**Scale MCP ADR Analysis Server for enterprise teams with hundreds of developers across multiple projects and repositories.**

**When to use this guide**: Managing ADRs for 50+ developers, multiple product teams, distributed organizations, or enterprise-scale architectural governance.

---

## 🎯 Quick Enterprise Setup

### Multi-Repository Architecture

**Most Common Use Case**: Coordinate architectural decisions across multiple repositories and teams.

```yaml
# .github/workflows/enterprise-adr-sync.yml
name: Enterprise ADR Synchronization

on:
  schedule:
    - cron: '0 */6 * * *' # Every 6 hours
  workflow_dispatch:

jobs:
  sync-adrs:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        repository:
          - frontend-platform
          - backend-services
          - mobile-apps
          - infrastructure
          - data-platform
    steps:
      - name: Sync ADRs Across Repositories
        env:
          GITHUB_TOKEN: ${{ secrets.ENTERPRISE_GITHUB_TOKEN }}
          OPENROUTER_API_KEY: ${{ secrets.OPENROUTER_API_KEY }}
        run: |
          echo "🔄 Syncing ADRs for ${{ matrix.repository }}"
          # Cross-repository ADR synchronization
```

### Federated ADR Governance

```json
{
  "enterprise_adr_config": {
    "governance_model": "federated",
    "organization_level": {
      "required_adrs": ["security-standards", "data-governance", "compliance-framework"],
      "approval_authority": ["architecture-council", "security-team"]
    },
    "team_level": {
      "autonomy_scope": ["technology-choices", "implementation-patterns", "local-architecture"],
      "escalation_triggers": [
        "cross-team-impact",
        "security-implications",
        "compliance-requirements"
      ]
    }
  }
}
```

## 🏗️ Enterprise Architecture Patterns

### 1. Hub-and-Spoke ADR Management

**Central Architecture Team + Autonomous Product Teams**

```yaml
# Enterprise ADR structure
enterprise_structure:
  central_hub:
    path: 'enterprise-./adrs/'
    scope: 'organization-wide'
    owners: ['architecture-council']

  product_spokes:
    - name: 'ecommerce-platform'
      path: 'products/ecommerce/./adrs/'
      owners: ['ecommerce-architects']

    - name: 'payment-services'
      path: 'products/payments/./adrs/'
      owners: ['payments-team']

    - name: 'user-platform'
      path: 'products/users/./adrs/'
      owners: ['user-platform-team']
```

**Implementation:**

```bash
#!/bin/bash
# scripts/enterprise-adr-setup.sh

echo "🏢 Setting up enterprise ADR structure..."

# Create central hub
mkdir -p enterprise-./adrs/{security,compliance,architecture,data}

# Create product spokes
for product in ecommerce payments users analytics; do
  mkdir -p "products/$product/adrs"

  # Copy enterprise templates
  cp enterprise-./adrs/templates/* "products/$product/./adrs/"

  echo "✅ Created ADR structure for $product"
done

echo "🎯 Enterprise ADR structure ready"
```

### 2. Matrix Organization Support

**Cross-Functional Teams + Domain Expertise**

```json
{
  "matrix_organization": {
    "functional_teams": {
      "security": {
        "repositories": ["all"],
        "adr_types": ["security-*", "*-compliance", "*-privacy"],
        "review_authority": "mandatory"
      },
      "platform": {
        "repositories": ["infrastructure", "platform-*"],
        "adr_types": ["infrastructure-*", "platform-*"],
        "review_authority": "advisory"
      },
      "data": {
        "repositories": ["data-*", "*-analytics"],
        "adr_types": ["data-*", "*-analytics", "*-ml"],
        "review_authority": "mandatory"
      }
    },
    "product_teams": {
      "autonomy_level": "high",
      "escalation_matrix": {
        "security_impact": "security-team",
        "platform_impact": "platform-team",
        "data_impact": "data-team"
      }
    }
  }
}
```

### 3. Geographic Distribution

**Multi-Region Teams with Time Zone Considerations**

```yaml
# .github/workflows/global-adr-coordination.yml
name: Global ADR Coordination

on:
  pull_request:
    paths: ['**/./adrs/**']

jobs:
  coordinate-reviews:
    runs-on: ubuntu-latest
    steps:
      - name: Determine Review Regions
        id: regions
        run: |
          # Determine which regions need to review based on impact
          echo "regions=us-east,eu-west,asia-pacific" >> $GITHUB_OUTPUT

      - name: Schedule Async Reviews
        run: |
          echo "📅 Scheduling reviews across time zones..."
          # 24-hour review window for global teams

      - name: Notify Regional Teams
        run: |
          echo "🌍 Notifying regional architecture teams..."
          # Region-specific notifications
```
