Architecture: This is supposed to be the stable element! And choosing the right architecture ensures that the software can be developed and maintained in the future! What initially appears to make sense often in reality turns out to be the first step toward an architectural failure. Unfortunately, when requirements, insights, or technologies change, the architecture must change as well. How can it then be future-proof? This presentation shows how the paradox can be resolved, and maybe not future-proof architecture - but long-term project success.
