If you host an EventModeling session it is important to get everyone on board quickly. The power of EventModeling lies in the simplicity of its building blocks and that it has only a few patterns. That means that people that are not familiar with it yet can get up to speed quickly.

Bring this sheet to your session in order to explain the pure basics.

Building Blocks
