System decomposition is the process of dividing a system into distinct services, modules, and components while defining clear boundaries. It documents architectural trade-offs and identifies structural risks introduced by the chosen separation.

Define service boundaries by evaluating architectural drivers and domain models, then document the decisions using Architecture Decision Records. This process flags risks and generates text-based system diagrams showing data flows.

Evaluate in-line versus separate components when defining system boundaries based on architectural drivers. This boundary evaluation determines whether functionality should remain integrated or split into distinct modules to mitigate architectural risks.

Generate ADRs by analyzing architectural drivers and domain models to define service boundaries. The decomposition process documents significant boundary choices and trade-offs, producing a summary report of the architectural decisions.

Automating system boundary definition requires loaded artifacts like architectural drivers and component registries for accurate analysis. Without these inputs, the automated decomposition cannot properly evaluate boundary trade-offs or identify architectural risks.

Yes, system decomposition generates text-based system diagrams with named services, modules, and data flows. These diagrams visualize the defined boundaries and are included in the summary report alongside the documented ADRs.
