Event Storming Masterclass
Model your business domain with Event Storming: from Big Picture through the Process level to the Design level, discover business events and build maintainable systems.
A two or three day workshop where we explore the Event Storming technique. Understand your business domain and analyse its processes through visual modeling and collaborative exploration. Learn how to use Big Picture level to brainstorm and discover business events, Process level to dive deep into each process and Design level to create a detailed model of the system.

Content
Event Storming is a powerful visual modeling technique that helps understand complex business domains and systems. In this course, we learn the principles of Event Storming and how to apply them. We cover best practices that help identify problems and develop solutions, practicing these techniques through practical examples and exercises.
The workshop includes the following topics:
- Understanding Event Storming technique
- Short training on a real-world example
- Practical Big Picture level session
- Focus on business domain discovery
- Model key processes
- Find pivotal events
- Prepare draft of subdomains
- Practical Process level session
- Dive deep into modeled processes
- Find actors, commands, policies and read models
- Validate draft of subdomains
- Practical Design level session
- Create detailed model of the system
- Define bounded contexts and their interactions
- Find aggregates
- Refine and validate the detailed design with iterative feedback
The actual course content may differ from the above depending on the trainer, delivery, duration and the composition of participants.

More about Event Storming
Event Storming is a collaborative workshop method for visually modeling complex business domains. It was invented by Alberto Brandolini and combines practices from Domain-Driven Design with lightweight, accessible visualization — requiring no software support at all. Using colored sticky notes on a large modeling surface, all participants — domain experts and developers together — surface knowledge about domain processes.Further resources:
History
Event Storming was invented in 2013 by Alberto Brandolini, originally as a rapid method for modeling complex business processes in the spirit of Domain-Driven Design. The approach emerged from frustration with lengthy, overly formal requirements-gathering workshops and the desire to make domain knowledge visible quickly and collaboratively.
Over the years, Event Storming evolved from a pure DDD tool into a versatile instrument for organizational modeling, process optimization, and software design. Today it is structured across three levels — Big Picture, Process Level, and Design Level — and is one of the most widely used collaborative modeling techniques in agile software development.
