The drawing

What an interaction overview diagram is.

An interaction overview diagram gives a high-level view of how a scenario moves between user actions, system behavior, and connected services. It uses a flowchart structure to connect the major interactions and decisions without showing every individual message.

Use it when a sequence diagram would be too detailed for the first conversation. It is especially useful for comparing success, retry, error, and escalation paths across one system scenario.

FAQ

Common questions

What is an interaction overview diagram?

It is a high-level diagram of how related interactions and decisions fit together in a larger scenario.

When should I use an interaction overview diagram?

Use one to explain a cross-system scenario before documenting detailed messages, implementation, or individual API calls.

How does it differ from a sequence diagram?

A sequence diagram emphasizes messages and time order between participants. An interaction overview diagram emphasizes the high-level flow between scenarios and decisions.

What should I describe in the prompt?

Name the trigger, participants or services, important checks, alternate outcomes, retries, and the final result.
