Two teams work on the same system. They describe its core process completely differently. Every release, something breaks at the seam between them.

Event Storming is Alberto Brandolini's collaborative workshop format. You use coloured sticky notes to map domain events, commands, aggregates, and policies chronologically — surfacing hidden complexity by getting everyone in the room to describe what actually happens.

A left-to-right timeline of sticky-note style domain events from "earlier" to "later", such as user signed up, cart created, order placed, payment authorised, order shipped, and refund requested.
