Alberto Brandolini , Book Author at Leanpub at Avanscoperta S.r.l.Talking about the Big Picture vs Detailed Model... one does not exclude the other. But they happen at different moment in time. A first high level eventstorming might clarify the whole context and goals, while a second focused round will drill into the mechanics. But I have to admit that the tool is flexible enough to let me take last minute changes, when I discover that there is a different problem/goal from the one originally stated.Reply

Alberto Brandolini , Book Author at Leanpub at Avanscoperta S.r.l.Many things together: depending on the people in the room, the discussion might be focused more on the technical side than on the process side. When investigating on value generation, I try to steer the discussion around the different personas/roles involved and to the value created for/by them. This leads to more Domain Events, not necessarily turned into software.Reply

Hoang Huynh , Head of Business Innovation, Entrepreneur, Advisor, Lecturer at EXAGE, White Label, First FlightLove the concept! I did try to use the Event Storming approach into a Service Design context. I always start the domain exploration with a stakeholder map and a system map which basically map all the actors (people) and the actors (services and data info flows). Tackle the problem from the event part of the domain is really really effective and appealing, but the struggle I found is mostly related to the fact that the event domain is too broad to be manage along with other different activities strictly related to our field. People and services are de facto outside your modelling system: they are causes and effects, you can work with them, but their relationships are not physically tracked. On the other side, the big picture is ensured only if the model is somehow comprehensive or complete to a good enough level of detail, but as far as I understand, it is better to subdivide the domain into several areas and try to model them in depth, instead of having a big less accurate modeling. An interesting approach I use, is to use event storming not for domain analysis, at the beginning of the strategic thinking, but at the end of the analysis, after the user research and the service blueprint. With the service blueprint I map the backstage flows my project will require. Usually I don't have time to explicitly visualize the As-Is, therefore small focused session of Event storming are good to bridge the designed blueprint with all the "technical" part of the project: requirements, stories and definitions. In order to be effective I do sacrifice the big picture, but at that stage, it should be / has to be already clear to all the stakeholders (hopefully).Reply
