Crunching ‘real-life stories’ with DDD EventStorming and combining it with BDD Example Mapping


To really understand what your users will need, you want to have a first-hand experience from ‘real-life stories’ before you can model and create your software. While both the DDD and BDD techniques emphasis on ‘real-life stories’ by doing collaborative deliberate learning, they both focus on different goals. DDD focuses more on creating bounded contexts in which a single model is created, BDD focuses more on different scenarios and can create executable specifications as an outcome.

By doing EventStorming and using techniques from BDD, such as Example Mapping or Feature Mapping, you can create more insights. You can simultaneously create a model and executable specifications for your user needs. This way, you can write software and tests which matches the shared understanding of the user, creating a ubiquitous language. Value will be shipped at a faster pace.

In this session, Kenny will explain how to do Process EventStorming. He will use Example Mapping, or Feature Mapping to get more insights into his process. The outcome can drive your Software Modelling EventStorming and create Executable Specifications
