"Innovation & Value with Scala, not because" @ XP Days DE 2015

This is a talk that was held at XP Days Germany in Karlsruhe on 26-Nov-2015.

It first covers how we, the team at our current product, made our technology choice in favor of Scala. It continues to take a look at the wanted and unwanted consequences of this choice and closes with my thoughts on how, if at all, it enabled the team to deliver innovation and value to our business.
