Łukasz Szydło Language: English Delivering the right software can be a challenge. You can have resilient architecture, modern flat UI, be intrinsically motivated, use sexiest tools and languages, and it all does not matter if a software you produce does not solve the right problem. Even when you know what the right problem is, you have to figure out which set of features will solve it; then how to transfer this knowledge to the whole team so that they know what to implement. During my presentation I will try to make sense out of it and show you some tools and techniques that you can use. P.S. if you think "user story" or "use case" is enough think twice.
