- Define boundaries
- Handle shared data
- Plan migration

### 2. Consistency Pattern Selection
- Evaluate patterns
- Choose appropriate
- Design implementations
- Document tradeoffs

### 3. Saga Design
- Define sagas
- Design compensation
- Handle failures
- Test scenarios

### 4. CQRS/ES Patterns
- Design read models
- Plan event sourcing
- Implement projections
- Handle consistency

### 5. Data Mesh Design
