Implementation Strategy

Phase 1: Core Business Engine (Epic #64) - Weeks 1-7

Focus: Template rendering and mathematical calculations Dependencies: None (builds on existing foundation) Critical Path: Template Engine → Expression Evaluator → CLI Integration

Phase 2: Automation & Scale (Epic #65) - Weeks 8-17

Focus: Batch processing and workflow orchestration Dependencies: Epic #64 (Template & Calculation Engine) Critical Path: Batch Engine → Data Integration → Workflow Orchestration

Phase 3: Integration & Professional Output (Epic #66) - Weeks 18-24

Focus: External systems and professional document export Dependencies: Epics #64 and #65 Critical Path: External Connectors → Export Engine → Security Framework

Total Timeline: 24 weeks (6 months)

Architecture Integration Points

New Components (Added)

• Template Engine: Core rendering with variable substitution
• Expression Evaluator: Mathematical calculations and business logic
• Batch Processing: Multi-document operations with progress tracking
• Workflow Engine: Multi-step process orchestration
• Export System: Professional output formats (PDF, DOCX, HTML)
• External Connectors: Database, API, and file system integration

Quality Assurance Framework

Testing Strategy

• Unit Tests: >95% coverage for all new components
• Integration Tests: Comprehensive testing with existing systems
• Performance Tests: Enterprise-scale performance validation
• Backward Compatibility: Ensure all existing functionality preserved

Validation Requirements

• Template Validation: Syntax checking and data schema validation
• Batch Validation: Quality gates for large-scale operations
• Security Validation: Enterprise-grade security testing
• Compliance Validation: Audit trail and regulatory compliance testing

Risk Management

Technical Risks (Mitigated)
