J-Fall 2018: Kenny Baas-Schwegler & João Rosa – 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”. EventStorming is a visual technique that minimizes 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, EventStorming can be quite an overwhelming experience. Developers can be left with the question of how to turn a few stickies on a wall into working code. Join us in this talk in which we show the basic principles of EventStorming. We will cover the different forms of EventStorming and in which situation they best can be applied. And, we will show how you can leverage DDD (Domain-Driven Design) patterns in an EventStorming software modelling session that will ultimately result in coding TDD (Test Driven Development) style!

Kenny Baas-Schwegler

Kenny Baas-Schwegler is a Software Engineer and Consultant focusing on software quality at Xebia. He mentors and coaches teams by using practices and techniques from Domain Driven Design, Behaviour Driven Development, Test Driven Development, and Continuous Delivery. He is an advocate for multidisciplinary collaboration in open spaces. By using techniques such as Event Storming, and Example Mapping, he helps engineer requirements to design and model software. With these methods, he aims to create a transparent, collaborative domain space with constant and instant feedback when delivering software. Besides his daily work, he also helps organise meetups for Behaviour Driven Development NL and Domain Driven Design Nederland.

João Rosa

João Rosa is a Software Developer, focused on delivering quality software that matters. Believes in the software crafts to provide software in sustainable peace; he is a DDD, BDD and TDD practitioner. Can’t live without his CI/CD pipeline. During his career he always pushed the teams and himself to improve the communication, reducing the gap between developers and the business. When he is not on his duties, you can find him traveling with his wife, or laying down on the beach reading a book. João is an amateur cook in his remaining time.
