Where I currently work (< 60 employees), management decided to try to switch to a flat structure similar to what is described in this handbook. We are still in the bootstrapping phase. However, I noticed that I could not find a lot of serious/deep evaluation material, like, companies that really did it and discussed it in retrospective, nor anything similar in management literature. Also, I noticed that there are no good sw tools that help you organizing, the standard SCRUM tools are not enough and instead we would like to have something that allows to easily keep track of who is working on what and how, let's say more about the connections between the "teams" than their progress. Any tips?
