What is Scrum of Scrums?
A Scrum of Scrums, also known as Meta-Scrum, is a scaled agile technique used to connect multiple Scrum teams who work together on a complex solution.
Having a higher number of members in a single team increases the lines of communication. Due to this, smaller Scrum team sizes are recommended. So, when working on complex projects, the large group team is split into smaller Scrum teams. This helps to reduce lines of collaboration and maintain personal collaboration. These teams have their daily standups to discuss the tasks for the day. In these, they choose an 'ambassador' to participate in the Scrum of Scrums. The Scrum of Scrums is hence a meeting of ambassadors from the smaller Scrum teams.
These ambassadors may be a technical contributor, Scrum master, a product owner or a manager. Teams usually alternate their representatives over the course of the project.
In the Scrum of Scrums, a rep from each Scrum team shares major updates on the team's work. The rep talks about the team's progress and challenges faced. This usually happens after the daily standups, so that they convey the latest info.
The meeting is a way to enable teams to have effective cross team collaboration. It promotes transparency and adaptation at scale when working on a complex project. Teams highlight dependencies and tackle integration and conflict points. This technique is the oldest and most commonly used agile scaling framework.
History of Scrum of Scrums
Jeff Sutherland and Ken Schwaber, two of the pioneers of Scrum, first used the Scrum of Scrums method in 1996. It arose from a need they both had, to coordinate eight business units. Each of these had multiple product lines. Due to this, an effective way to bring about sync between the members was needed. To tackle this, the Scrum of Scrums came into being.
Inspired by this instance, Jeff wrote about it publicly for the first time in 1996. The article, 'Agile Can Scale: Inventing and Reinventing SCRUM in Five Companies' brought popularity to the Scrum of Scrums. This method has since been in use all over the world.
The Structure of Scrum of Scrums
The below diagram gives a visual representation of the structure.
Consider that the people working on the project are about 35 in number, split into 5 Scrum teams of 7 members each.
Now, these teams have their daily Scrum meetings/ standups. One member then represents the team in a Scrum of Scrums. This is shown in the top row
If needed, on bigger projects, teams also make use of Scrum of Scrum of Scrums. This, as the logic follows, would be reps chosen from multiple teams of reps. Each of these teams would actually be a Scrum of Scrums.
Conduction of Scrum of Scrums
When the Scrum of Scrums takes place, the team reps answer the following questions:
- What was the work done by the team since the last meeting?
- What work will the team do before the next meeting?
- Is your team facing any impediment which is slowing its work?
- Does your team's work have the chance of obstructing any other team's work in any way?
- Is the work of any other team obstructing your work?
The exact questions could differ a bit, but these sum up the general agenda of the meeting.
As already stated earlier, the team rep or ambassador is chosen by the team. These could be a technical contributor, Scrum master, product owner or manager. The person representing is usually changed every few days or so depending on the team and the stage of the work. Also, more than one person could represent, for example, the Scrum master as well as any developer.
Generally, the Scrum of Scrums is conducted on a daily basis, but this isn't a must. This depends on the project needs. The teams decide the frequency of the Meta-Scrums. For example, it could be daily, or twice a week, or less frequently based on the project.
Purpose of Scrum of Scrums
The purpose of the meeting is to achieve better team collaboration on a complex project. These are some of the things it helps achieve:
- Make cross-team collaboration easier in case of complex projects involving large teams.
- Enhance team productivity in individual Scrum teams.
- Make prioritising tasks easier through collaborative discussions.
- Solve problems that arise during the course of the development.
- Keep the deliverables of the project on track.
- Gives a clear picture of the path taken by the team to achieve the goal to all members.
- Ensure that the work of one Scrum team isn't a hindrance to other teams.
- Combine the productive output of multiple teams effectively into a single entity.
Best Practices for conducting a Scrum of Scrums
By now, you'd have understood most things about a Scrum of Scrums and are ready to conduct these in your teams. To help you with conducting these, here are a few points to keep in mind.
- Keep a cap on the amount of time the meetings take. Ideally, keep it at around the same time that your daily standups take.
- Set a frequency and stick to it. If your team decides to have the Scrum of Scrums every two days, make sure it happens.
- Ensure that each member of the team is aware of what will be discussed during the meeting. The participants should prepare what they want to say to avoid wasting time.
- Choose the right person for the meeting. This could vary based on the stage of the project and it's a good practice to alternate members for this.
- Make sure that there is time set aside for solving issues. Note that this isn't just to get a status report but rather to tackle issues that come up.
- Create an environment of trust and transparency. Team members should feel at ease and share their concerns openly.
- Each participant in the Scrum of Scrums should inform their team of the things discussed. This transfer of information is quite important.
