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”. Event Storming 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, Event Storming 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 Event Storming. We will cover the different forms of Event Storming and in which situation they best can be applied. And, we will show how you can leverage DDD (Domain-Driven Design) patterns in an Event Storming software modeling session that will ultimately result in coding TDD (Test Driven Development) style!

  9. The fundamental horror of this anti-pattern is that it's so

    contrary to the basic idea of object-oriented designing; which is to combine data and process together. - Martin Fowler
  10. What's worse, many people think that anemic objects are real

    objects, and thus completely miss the point of what object-oriented design is all about. - Martin Fowler
  11. None
  12. Confirmation Bias

  13. None
  14. It is not the domain experts knowledge that goes to

    production, it is the assumption of the developers that goes to production - Alberto Brandolini
  15. To communicate effectively, the code must be based on the

    same language used to write the requirements - the same language that the developers speak with each other and with domain experts - Eric Evans
