Describes the static and logical organization of a system into components, interfaces and interaction patterns for structured design and communication.
System Structure describes the static and logical organization of a software system, including components, interfaces and interaction patterns. It provides an abstract model for system design and decision-making regarding boundaries, responsibilities and deployment levels. It supports documentation, architectural reviews and team alignment.
Measures how often APIs/interfaces are changed; indicator of structural stability.
Time from commit to production deployment of a component; measures deploy autonomy.
Share of incidents affecting multiple components; indicator of coupling.
Splitting a large monolith into clearly bounded modules with defined interfaces.
Use of layered model (presentation, domain, persistence) to separate concerns.
Definition of service boundaries, data ownership and communication patterns for microservices.
Analyze existing architecture and collect relevant artifacts
Define core components, interfaces and responsibilities
Create architecture documents and review with stakeholders
Establish governance and decision processes for future changes
