Loose coupling and modular architecture
Description
Simpl-Opem shall ensure loose coupling between components, allowing modules to interact through well-defined interfaces while minimising dependencies to enable independent evolution and scalability.
SMART Breakdown
- Specific : Modules shall communicate exclusively via well-defined interfaces (e.g., REST APIs, message queues) and avoid shared state, direct object references, or hardcoded dependencies. Contract-first API definitions shall serve as the foundation for inter-module communication.
- Measurable : Coupling metrics shall be monitored using static code analysis tools and reviewed during architecture validation phases. Dependency graphs shall be maintained and assessed as part of CI/CD quality gates.
- Achievable : Loose coupling will be enforced through architectural patterns such as dependency injection, publish/subscribe via Event Bus, and Service Registries to manage dynamic binding of components.
- Realistic : These patterns are standard in modern distributed architectures (e.g. microservices, service mesh, EDA) and align with Simpl-Open’s modular deployment and governance model.
- Timely : Loose coupling shall be incorporated during the initial architecture definition and continuously evaluated during implementation, refactoring, and system evolution reviews.
