Late in the evening at the XP2013 in Vienna, I hosted an open space session under this title and am still surprised at how many participants actually joined me in discussion. It seems that I was not the only one faced with this question. While the session did not provide me with the sought-after perfect solution, it did give me an insight into how other companies structure the collaboration between individual ScrumMasters in order to act as a singular, strong force of change agents. Here are some of the options that came up in conversation and that I can relate to due to having experienced them myself. Of course, these options may vary accordingly.
In the end, however, I do not think that there is a right or a wrong answer. The only question that really matters is whether the Scrum-Teams are delivering valuable features or not. And if they aren‘t, the impediments hindering their productivity must be addressed and solved as quickly as possible. I do believe that a Team of like-minded persons with the same mission can achieve more than singular change agents. Once the ScrumMasters understand this for themselves, I am convinced that the right ‘how to‘ will come automatically. And this will probably differ depending on the persons involved and their specific system.
