From EventStorming to CoDDDing


To really understand what our users need so that we can build the right thing, we want to have a first-hand experience of ‘real-life stories’ before we model and create our software. To quote Alberto Brandolini “it is not the domain expert’s knowledge that goes into production, it is the developer’s assumption of that knowledge that goes into production”.

Visual collaboration are tools that minimize assumptions by engaging in collaborative deliberate learning across different disciplines. This helps to solve complex business problems in the most effective way.

Although the learning of the domain helps us to understand the domain better, visual collaboration tools like EventStorming and Example Mapping can be quite an overwhelming experience. Developers can be left with the question of how to turn a few stickies or index cards into working code.

Join us in this talk where we will leverage Eric Evans model exploration whirlpool. We will show how to create a shared mindset by telling a story with visual collaboration tools like EventStorming and Example Mapping. From there start to propose models by leveraging Domain-Driven Design patterns. We end up going from our model to code probe by doing outside in Test Driven Development! You will leave with the knowledge to go from visual collaborate modelling to coding while refining your ubiquitous language.

As a socio-technical systems thinker, agile architect, and Domain-Driven Design expert, I work with CTOs, managers, architects, and teams to change how we design software. Through facilitating and doing collaborative modeling, I catalyze organizations, teams, and groups of people to an agile architecture approach to building sustainable quality software products.
