In 2011, I worked for Qik, a startup that got aqcuired by Skype. At that time Skype was in the middle of an agile transition. Аfter aquisition, Qik team was told to adopt the Agile process used by Skype. I worked with the team as an agile coach. After adopting Skype's process, our ability to deliver was brought down to almost zero. In this talk, I'll tell you the story as it happened, analyze the key problems that we faced and describe how we finally solved them.
