#75 - Domain Storytelling: Building Domain-Driven Software Collaboratively - Stefan Hofer

“It’s great if developers have understanding about the domain, because then they can propose better solutions, that’s not necessarily the same solution that the users have in mind, which are often limited by what they know."

Stefan Hofer is the co-author of Domain Storytelling–a collaborative, visual and agile way to build domain-driven software. In this episode, Stefan shared the story of how he came up with Domain Storytelling and explained how this technique can help us understand business domain better and bridge the misunderstandings between software developers and domain experts. Stefan walked us through how the modeling works, including the notations and other pictorial aspects of it, and emphasized the importance of the collaborative aspect of Domain Storytelling. Stefan then explained how Domain Storytelling differs from other similar modeling techniques, such as Event Storming, and gave practical tips on how to run a successful online collaborative workshop.
