Webinar #9 - Radek Maziarka - Modularization with Event Storming Process Level

This time we had a special guest: Radek Maziarka. He explained to us Modularization with Event Storming Process Level.

Radek showed intriguing and actionable heuristics on how to get from the sticky notes to the modular design. He showed ways how to crunch and challenge the initial assumptions

He tackled that from many angles like:
- single-point of knowledge
- reactions between processes,
- reusability,
- language differences,
- data usage patterns,
- and more!

Radek wrote about his workshop:

"Typically we tend to modularize by business processes. It's the easiest way, but on multiple occasions, it can lead us astray. We end up with data divided into various places and communication multiplicated. There must be another way to achieve modularization! And there is. During our Event Storming Process Level session we will use different modularization heuristics to achieve better autonomy and more cohesive communication. We will use these techniques on an actual domain - Bike Rental - to prove their validity. We will finish our session by defining a bounded context and communication across the system."
