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!
