Product Return Event Storming

This event storming diagram maps an e-commerce return from the customer's request through a completed refund. It separates the return-eligibility policy from the warehouse receipt and refund policy, which helps the group discuss ownership and exception handling. The sequence is intentionally small enough for a workshop wall or card. Expand it with rejected returns, inspection results, partial refunds, exchanges, and carrier failures when those rules become relevant. Use event names that state completed facts, such as Item received, so downstream teams can identify the exact moment their process is allowed to begin. Review the underlying definitions and totals before using this view to make an operational decision.

よくある質問

Why is return eligibility a policy?

It reacts to a return request using business rules to decide what happens next.

Should a refund happen before receipt?

That depends on policy; this example issues it after the returned item is received.

What is an aggregate here?

A return or order aggregate can own the state changes represented by these events.
