How to conduct an event storming session

Let's walk through each of the steps involved in holding an event storming session with your team.

Step 0 — Create a legend of all the event storming constructs

Before we even get started, Vaughn Vernon recommends we use a legend so that the event storming constructs and their color schemes are well understood by all participants.

  • Domain Events — orange
  • Commands — light blue
  • Aggregates — yellow
  • Issues — red
  • Actors/Roles — light yellow or yellow with a stick figure
  • Views — green
  • Bounded contexts (boundary) - solid line + named w/ a pink sticky
  • Subdomains (boundary) — dashed lines + named w/ a pink sticky
  • Event Flow — arrows
