Collaboration between multiple Scrum teams: how to maintain alignment and prevent chaos

Context & Challenge

In Agile projects, multiple teams may need to work simultaneously on a single product or on closely related products. This introduces additional complexity: dependencies in code, design, or features must be managed, while each team still needs to be able to move independently. Without proper coordination, there's a risk of duplicated efforts, conflicting releases, or unnecessary delays.

‍

Alignment & Communication

Scrum of Scrums is a widely used method to keep progress and bottlenecks transparent across multiple teams. Every day (or every few days), teams send a representative to briefly align on what's happening and what help is needed. A joint Planning or Review session (e.g., monthly) can also help inform all stakeholders simultaneously. This creates a shared understanding of who is working on which features and what the priorities are.

‍

Concrete Example

• Joint Review: Once per sprint, each team demonstrates the delivered functionalities to the 'Chief Product Owner' and stakeholders in the same session. This way, they see each other's progress and can receive feedback together.
• Joint Planning: Start each sprint together with a short session where major dependencies are identified and prioritized.

‍

Shared Product Backlog or Goals

To maintain direction, teams often work with one overarching Product Backlog, managed by a Chief Product Owner. Alternatively, there might be multiple backlogs, all aligned with the same Product Goal. This prevents teams from working at cross-purposes or developing conflicting features. Organization-wide prioritization is essential: what is truly the most important thing for the product right now?

‍

Tips for a Shared Backlog

• Transparency: Everyone can see what's on the backlog and which items are intended for which team.
• Regular refinement: The Product Owner(s) discuss epics and features at a high level and break them down into team backlogs.
• Clear scope: Ensure it's clear who manages which epic or component to avoid duplicate effort.

‍

Manage dependencies

Multiple teams often mean dependencies in code (for example, Team B builds the API first, then Team A builds the frontend) or processes (Team X needs to deliver a design, Team Y implements it). Keep this transparent:

• Program Board or simple dependency list: Note down who is dependent on what.
• Plan sequences: If Team B delivers APIs, plan those first so Team A can proceed with them immediately.
• Scrum of Scrums: In each meeting, mark which dependencies have been resolved or new ones have arisen.

‍

Communities & culture

Foster a culture where not every team primarily defends its own sprint goals, but where everyone collectively strives for the product. Communities of Practice can connect teams around specialisms (e.g., UX, DevOps), so that best practices are widely shared. This prevents differences in quality, coding standards, or user experience between teams.

‍

Inspiring Case Study

“At our company, three teams were working on one product, but they were on separate floors. Communication was difficult, and releases often got stuck. After we introduced a weekly joint planning day, we noticed that releases ran much more smoothly, and the teams gained a better understanding of each other's work.”

‍

Triggers for Interest & Engagement

• Relatable Problem: Teams experiencing dependency issues immediately want to know how Scrum of Scrums and coordination techniques can help.
• Practical Tips: “Use a shared chat or stand-up between teams for urgent alignment” makes it practical and usable.
• Shared Successes: Before-and-after stories build trust.

Generate Clicks & Traffic

• SEO keywords: “multiple Scrum teams collaboration”, “Scrum of Scrums explanation”, “agile multi-team coordination”. Incorporate these terms into the metadata and snippet.
• Titles: Terms like “Scrum of Scrums” and “multi-team” attract the right target audience.

Conclusion

Collaboration between multiple Scrum teams requires additional coordination and communication channels. Whether you choose Scrum of Scrums, a Chief Product Owner, or a shared backlog, the core is clear alignment and a culture of collaboration. This way, you prevent chaos, increase effectiveness, and keep all your teams aligned towards the overarching product goal.
