Event modeling is a compact workflow of five elements — command, event, read model, gear, UX/UI — and seven steps that turn sticky-note brainstorms into a development blueprint. The example uses a ship-visit declaration: commands validate input, events record facts, gears automate translations or trigger follow-up commands, read models feed UIs, and slices map to teams for vertical-slice delivery and time estimates. Tools include Miro plugins, eventmodeling.org and Proofboard, and the plugin exports JSON to generate code.
