Everyone wants a good architecture, so most of us learned all about design patterns, microservices and all the other important things. But with the raise of DDD it is getting more obvious again: We need to focus more on understanding the functional requirements and specifications instead of thinking too much about the solution. This doesn’t mean we need to go back to the “Big Design Upfront” days of waterfall, but it seems agile made us forget, that some planning is actually quite useful. Most of the time we haven’t even understood the problem before we start coding. I want to show how architecture katas can help us to train methods like events storming or to focus more on requirements in general.
