I've recently been introduced into Domain Driven Design and we've done a lot of event storming in a simulated environment with a lot of people.
Now I'm back in the real world and I've been given a task but I need deeper insight in the process.
Does it make sense to go out event storming on your own to do this? Or is event storming on your own just plain silly?
Event Storming article has the following to say on the matter:
It is important for an event storming workshop to have the right people in presence. This includes people who know the questions to ask (typically developers) and those who know the answers (domain experts).
So no, I think that's a definite no. Though if you're generating ideas for yourself, there's nothing wrong with that. I simply don't think it can be called event storming without others. If anything, have a peer review your ideas to get some feedback for your insight.
