Creating a Modular Software Architecture

Key Design Principles:

• Microservices architecture separating distinct functional areas
• API-first approach enabling clean system boundaries
• Domain-driven design aligning with clinical workflows
• Containerization supporting scalability and deployment flexibility

Advantages of Modular Design:

1. Independent evolution of system components
2. Selective replacement of individual modules without complete system changes
3. Parallel development by multiple teams (critical for SAFe implementation)
4. Incremental delivery of new capabilities
5. Technology diversity when appropriate for specific domains

Hospital-Specific Benefits:

• Ability to integrate specialized clinical systems (e.g., PACS, LIS)
• Flexibility to adapt and extend patient portals to meet specific needs
• Capacity to quickly implement new KHZG funding modules
• Support for diverse clinical workflows across departments
• Readiness for future healthcare innovations without major rewrites
