We are running a project with a team of around 60 people using Scrum. Half of the team reports to one project manager; half to another project manager. Those 2 project managers meet with the test lead and the program manager in a daily Scrum of Scrums (SoS). Given that this is new, there is some concern about keeping the SoS short and efficient.
I've read several good articles on the topic of SoS, but most focus on technical integration between the Scrum teams via the SoS. What about reporting non-technical issues and status during the SoS?
Specifically, the project managers are not technical (and neither is the program manager). How detailed should the (non-technical) report be in the SoS and how can we keep this short and efficient?
