From Vision to Code: Functional Domain Modelling

Modern collaborative methods such as EventStorming help to bring together subject matter experts and developers. Domain Modeling goes one step further and enables joint work directly on the code. In this live coding event you can watch and even participate directly on a practical example.

Our PO brings along the results of an EventStorming. You will get a short overview so you can pretend that you have been involved during the storming. The PO will than explain the requirements to the developer/modelling expert who models the domain according to your suggestions.

The result will be a model of the domain using a type system. We will demonstrate this using TypeScript, but the same approach can be applied using any language with a suitable type system.

Even non-programmers, such as our product owner, will be able to verify the model and provide feedback directly to the developer. The final model, which provides a clear understanding of the invariants and behavior of the system, can be used directly to begin actual implementation by developers. This is the power of functional domain modeling!
