Europace is a network-centric organization within a network of organizations (Hypoport). It uses the self-organization framework Holacracy as its operating system---loosely coupled, autonomous teams are working together for a common purpose. But with autonomy also comes a trend towards self-sufficiency. In the years after starting with self-organization we experienced a lot of “reinventing the wheel” instead of company-wide collaboration. In order to find a way out of this dilemma we looked at the open source world, especially on how collaboration works in such a distributed world. What we found was The Apache Way. Next, a group of people interested and experienced in Open Source founded a community of practise at Europace. Together, we run experiments for applying the patterns of The Apache Way at our teams. As a result of those experiments these patterns can nowadays be found everywhere at Europace, especially when it comes to collaboration between teams. But we did not stop there, we kept on running experiments in order to improve the InnerSource experience at Europace. In this talk you will learn which experiments we run, how we did it and what we discovered on our journey so far.
