Architecture With Explicit Boundaries
EPIC is structured around clear ownership boundaries between platform capabilities, core services, product modules, and supporting infrastructure.
Architectural Layers
Architectural principles, doctrines, governance, and shared platform rules.
Core platform capabilities and services consumed by products.
Business applications and product modules consuming platform capabilities.
The execution environment where platform and product functionality operate.
Architecture Lifecycle
Architecture decisions are treated as governed knowledge rather than undocumented implementation details.
Discover → Retrieve Knowledge → Reason → Plan → Implement → Verify → Review → Govern → Synchronize
Why Boundaries Matter
Clear boundaries make it easier to:
- Identify ownership
- Reuse capabilities
- Control dependencies
- Validate implementations
- Prevent architectural drift
- Evolve the platform safely
Reference Implementations
Proven implementations can become architectural references when they satisfy the platform's reference implementation governance criteria. Reference implementations provide reusable patterns for architecture, lifecycle, verification, and governance.
