EventStorming is considered a low-tech workshop because it is done using a pen and paper—a lot of paper, actually. Let’s see what you need in order to facilitate an Event‐ Storming session:

Modeling space

First, you need a large modeling space. A whole wall covered with butcher paper makes the best modeling space, as shown in Figure 12-1. A large whiteboard can fit the purpose as well, but it has to be as big as possible—you will need all the modeling space you can get.

Sticky notes

Next, you need lots of sticky notes of different colors. The notes will be used to represent different concepts of the business domain, and every participant should be able to add them freely, so make sure you have enough colors and enough for everyone. The colors that are traditionally used for EventStorming are described in the next section. It’s best to stick to these conventions, if possible, to be consis‐ tent with all of the currently available EventStorming books and trainings.

Markers

You’ll also need markers that you can use to write on the sticky notes. Again, sup‐ plies shouldn’t be a bottleneck for knowledge sharing—there should be enough markers for all participants.

Snacks

A typical EventStorming session lasts about two to four hours, so bring some healthy snacks for energy replenishment.

Room

Finally, you need a spacious room. Ensure there isn’t a huge table in the middle that will prevent participants from moving freely and observing the modeling space. Also, chairs are a big no-no for EventStorming sessions. You want people to participate and share knowledge, not sit in a corner and zone out. Therefore, if possible, take the chairs out of the room.1
