When: January 29-30, 2019
Where: Amsterdam, Netherlands
Two day workshop with Kenny Baas-Schwegler, Bruno Boucard, Thomas Pierrain.
Creating multiple models for the same problem is one of the more important lessons that Domain Driven Design teaches us. It is a lot cheaper to quickly iterate over them and throw away less useful prototypes before we even start coding. However, creating multiple models can be hard. When we begin gaining insight from our domain, we suffer a lot from cognitive biases that get in our way to gain new insights. We need these insights before we even start thinking about modelling. Tools like event storming and example mapping can help us to deliberate discover, and battle these biases. They help you quickly gain insight into the problem space. But the fallacy here is that we can get locked into the tool, and get stuck again.
What you will learn
In this two day workshop, you will learn the essentials of event storming and how it can help you gain the necessary insights you need to deliver quality software. With our newly acquired domain knowledge, we can then start exploring the solution space. During the exploration, we begin to design and model multiple models for the same problem with Domain Driven Design patterns. This way of visualising gives us the power to quickly iterate over the different models and figure out which model will be the best to use for now. Eventually, we start our coding journey TDD style, iterating over the model to refactor towards deeper insights while discovering how hexagonal architecture may help us to protect our domain code from the technical concerns, in the long run.
Kenny Baas-Schwegler - Software Engineer Consultant
Kenny Baas-Schwegler is a software engineer and consultant focusing on building quality into software delivery at Xebia. He mentors, coaches and consults teams by using practices techniques and tools from Domain Driven Design, Behaviour Driven Development, Test Driven Development, and Continuous Delivery.
Through Aikido training he learned the most efficient way to work together. To get the outcome that all parties want, energy should not be blocked but should be bent and influenced. The philosophy behind this line of reasoning is not only embedded in his personal life, but also in his work life. He is an advocate for multidisciplinary collaboration in open spaces. By using and combining tools such as EventStorming, and Example Mapping, he helps engineer requirements to design and model software. With these approaches, he aims to create a transparent, collaborative space with constant and instant feedback when delivering software.
Besides his daily work, he also helps organise several meetups for Behaviour Driven Development NL, Domain Driven Design Nederland and EventStorming Netherlands and also often speaks and gives hands-on workshops at conferences and meetups.
