The Scrum of Scrums (SoS) is a technique for scaling Scrum and other Agile techniques to larger efforts. On paper, the SoS is a simple extrapolation of the daily Scrum or stand-up meeting that has become a hallmark of the practice of Agile. A typical stand-up meeting occurs on a daily basis so that all of the team members of can coordinate and plan daily activities. Classically the team uses the three question technique to organize the meeting. In a similar manner, a typical Scrum of Scrums acts as a focal point to help synchronize a team of teams or even teams of teams. There are four basics of a SoS that need to be understood before any nuances can be addressed.
- Who Attends: There are two basic schools of thought in picking SoS attendees. The first (and most common) school suggests that the Scrum Master attend the SoS. The Scaled Agile Framework Enterprise (SAFe) is an example of a methodology that leverages the Scrum Master during both the planning event and during the program increment. Alternately, the second group takes a more egalitarian approach (possibly more pragmatic) allowing the each team to select an attendee that can most easily convey or understand the current issues the team and the larger group are having at the time. For example, if design decisions are at the front, perhaps team members with the most UX acumen would make sense. In this scenario attendees would vary over time.
- Who Facilitates: Small SoS groups, for example a handful of teams that are co-located, may not require facilitation. The SoS can self-organize and execute the meeting with little overhead. However as the number of participants increases (I bound SoS meetings using the same 5 -9 members rule used in Scrum teams) or as the distribution of the members becomes more varied facilitation becomes more important. Facilitators help the team use the SoS practice, ensure logistics are set up and champion the schedule. In larger efforts, a program manager often delivers facilitation, or if practicing SAFe the Release Train Engineer performs the facilitation role.
- Frequency: Scrum of Scrums often follows the same pattern as the daily Scrum/stand-up meeting. A second frequency pattern is risk-based; the frequency of the SoS meetings varies depending on need. Early in a project the SoS meets daily as teams are forming, norming and as early decisions are being made. The SoS meeting become twice weekly in the middle of the project and then returns to daily as a release approaches.
- Format: Daily stand-up meetings commonly leverage the classic three question approach (What did I do? What am I going to do? and What are my blockers?). The Scrum of Scrums generally follows a VERY similar format with each participant answering the following four questions:
- What did my team do since the last meeting?
- What will my team do before we meet again?
- Is my team experiencing blockers?
- Is my team going to put something in another team’s path?
The meeting follows the same round robin approach with each participant interacting with each other. The facilitator (if used) should never be the focal point of the meeting, nor should the SoS devolve into a purely a status meeting.
The daily stand-up and the SoS are very similar meetings. Both meetings are held to share information, coordinate activities and to identify problems. The scope of SoS meeting is broader than a single team with the meeting providing coordination and planning activities within and across teams.
