Dan has been using Event Storming in a number of different contexts recently. He used it to model a legacy system, to design a new system, to understand several convoluted business processes, and primarily as an exercise in building shared understanding. He has also been coaching others and learning some surprising things about organisations. This session is a gentle introduction to Event Storming, some tips to help it along, and an experience report of Dan's recent adventures using it. Event Storming might just be the best thing since sliced domains.
