This document summarizes an internal innovation project at Trendevent 2017. It describes setting up a mixed team from two companies, Wijs and Proximus, to focus on developing a new telco product for millennials in one location. The team used agile methodology with 7 cascaded sprints across 3 subteams for design, development, and marketing. They learned that small tests are better than long spec documents, preparation is key, trusting the autonomous team is important, and flexibility and belief in the mission are more important than checking boxes.
