Modular boundaries are defined by focusing on domain responsibilities and interface contracts, using criteria for module scope and dependency direction to ensure stable interfaces during new feature decomposition.

The best way to organize module dependencies is applying communication principles and dependency direction criteria to enforce stable interfaces and prevent circular dependencies during subsystem refactoring.

Logical versus physical isolation is decided by evaluating module scope and dependency direction, applying decision strategies to choose between shared modules or establishing independent packages and repositories.

Domain-driven module decomposition improves cross-team collaboration by establishing stable interface contracts and clear module boundaries, preventing premature technical-layer splitting and reducing inter-team coupling.

Yes, the modular design framework supports subsystem refactoring by applying module scope and dependency direction criteria to restructure existing modules and ensure stable interface contracts.

Splitting modules by technical layers causes high coupling because it bypasses domain responsibilities, disrupting stable interface contracts and creating cross-boundary circular dependencies.
