Software design EventStorming, also called process modeling EventStorming, is a collaborative way to design or analyze a business process. It is useful when modernizing a product or process, or exploring what a better future state might look like. Compared with big picture EventStorming’s chaotic exploration of how a domain currently works, it is more structured and detailed. That brings the discussion closer to implementation without requiring software-specific concepts, so business and technical stakeholders can work together. section 8.4
Begin with a shared understanding of the current process and its problems. A big picture EventStorm can surface customer frustration, unreliable technology, and other opportunities; a process modeling session is one possible follow-up for designing a new or future-state process. Keep the design grounded in what users and the business need rather than reproducing an old system’s flaws with new technology. section 7.3.3 section 8.0
Choosing a process to redesign
An EventStorm may reveal that customers leave a purchasing flow before completing it. The group can investigate why, then use a focused process modeling session to explore a future process. The observed dropout is a reason to investigate, not proof that the group already knows the solution. section 7.3.1 section 7.3.3
Treat the model as a means of reaching shared understanding, not as an architecture decision by itself. Involve people with different knowledge of the process, make uncertainty visible, and follow up where user research or boundary validation is needed. EventStorming is one option alongside techniques such as Domain Storytelling; it is not a replacement for every other mapping approach. section 7.0 section 7.3.3 section 8.0
