Systematic capture and visualization of dependencies between components, services and teams to support architecture and decision-making processes.
Dependency mapping visualizes and documents dependencies between system components, services and teams to expose complexity, failure risks and integration points. It supports architecture decisions, impact analysis and release planning by structuring dependency paths, interfaces and coupling strength. Typical outputs include dependency graphs, prioritized remediation lists and an action catalog for decoupling and resilience.
Measures coupling density; high values indicate need for refactoring.
Shows number of hops in domains with high impact on failure.
Measures robustness and decoupling degree via asynchronous integration.
Mapping revealed tight coupling between payment and inventory systems, enabling stepwise decoupling and asynchronous interfaces.
Dependency mapping helped identify affected services and plan test priorities and canary strategies.
Mapping dependencies enabled targeted migration of databases and stateful components and minimized downtime.
Identify stakeholders and define mapping goals.
Clarify data sources and ownership, set up automated extraction.
Create initial visualization and mark critical paths.
Derive priorities and create action plan.
Operational integration: establish monitoring, regular reviews and maintenance processes.
