When facilitating an EventStorming session with a group of people who have never done EventStorming before, I prefer to start with a quick overview of the process. I explain what we are about to do, the business process we are about to explore, and the modeling elements we will use in the workshop. As we go through the elements— domain events, commands, actors, and so on—I build a legend, depicted in

Figure 12-12, using the sticky notes we will use and labels to help the participants remember the color code. The legend should be visible to all participants during the workshop.
