Scrum of Scrums practice can be used for large teams. When a team grows beyond 9-10 people you need to divide your team into sub-teams. Each sub-team will have their own sprint backlog and conduct their own daily stand-up meetings. To get the information flow to work between the sub-teams a coordination meeting (scrum of scrums meeting) is needed.

The Scrum of Scrums (SoS) meeting has roughly the same agenda as the normal Daily Scrum, but here it is the communication between the teams (sub-teams) that is addressed. One or two people from each sub-team meet 2-3 times per week. The meeting is typically not timeboxed since problem solving is also part of the meeting.  Each sub-team presents the following information:

  • What have we done since last SoS?
  • What do we plan to to until the next SoS?
  • What impediments are we struggling with?
  • Are we about to put something in another sub-team’s way?

At the end of the meeting this groups walks through the impediment list and tries to solve them. After the meeting the following happens:

  • The people from the sub-teams present the result from the SoS on their next daily Scrum meeting.
  • The Main Scrum Mastercan report current status to customer, management or steering group.
  • Impediment owner performs action to eliminated the impediment.

Story based stand-ups can also be a technique to try if you have a larger team.

Boris Gloger has the following advice to run Scrum of Scrum meetings:

Here a my 3 Secrets to run them successful.

1. No ScrumMaster from the teams goes to the Scrum of Scrums = means, the team members goes to the Scrum of Scrums

2. Maintain a cross-team impediment backlog. You need a ScrumMaster to facilitate this meeting. I usually have a Super- ScrumMaster, Über-ScrumMaster, Master of ScrumMasters 😉 Call him as you like. f.e. Scrum Evangalist.

3. Ensure that the SoS makes sense to the teams. Again – impediments in this meeting needs to be raised, and solved until the next day. Either by the teams or by the Scrum Evangalist.
