Net Objectives started using Scrum in 1999. Three-four years later, we started using Scrum with larger organizations and adopted Scrum-of-Scrums as a way to coordinate multiple teams working together. While it sounds great in theory, we could never get it to work. And, although it is still promoted by many Scrum consultants, it still has a spotty track record at best. The challenge we believe lies in the fact that the intra-team dynamics that makes Scrum effective, are not the same as the inter-team dynamics required for Scrum-of-Scrums to work.
