Just keep in mind that the goal of the workshop is to learn as much as possible in the shortest time possible. We invite key people to the workshop, and we don’t want to waste their valua‐ ble time.

—Alberto Brandolini, creator of the EventStorming workshop

Ideally, a diverse group of people should participate in the workshop. Indeed, anyone related to the business domain in question can participate: engineers, domain experts, product owners, testers, UI/UX designers, support personnel, and so on. As more people with different backgrounds are involved, more knowledge will be discovered.

Take care not to make the group too big, however. Every participant should be able to contribute to the process, but this can be challenging for groups of more than 10 participants.
