Logical Architecture Diagram Template

Shows the internal structure of the system of interest by breaking it into a small number of logical components. Each component represents a major responsibility or capability, not a technology, service, or deployment unit. The diagram contains a single system boundary, no external users or systems, and no runtime or execution flow. It is used to explain separation of concerns and provide a stable, technology-agnostic view of how the system is organised.
