How to Structure Successful Refinement for Large Products with Multiple Scrum Teams

Working on a large-scale product with multiple strong Scrum teams introduces unique challenges—and opportunities—for a Product Owner. In a scaled environment, managing refinement requires strategic thinking and a clear approach to ensure alignment across teams. Here’s a practical guide to creating effective layers of refinement, balancing high-level goals with tactical execution, and optimizing your role as a Product Owner to drive success.

Why Refinement Matters in Large-Scale Products

Refinement sessions ensure that each Scrum team has a shared understanding of what’s coming next, aligns around common goals, and prepares thoroughly for upcoming Sprints. But with several teams in the mix, refinement takes on new complexity. Large-scale products require a structured, layered approach to refinement to enable collaboration and prevent misalignment.

Key Takeaways:Create layers of refinement to manage complexity.Focus on strategic goals as a Product Owner.Empower cross-functional teams to handle tactical execution.

Let’s break this down into actionable steps!

Layer 1: High-Level, Cross-Team Refinement

When multiple teams work on the same product, the first layer of refinement should happen at a high level. This step sets the foundation for clear Sprint goals and ensures every team is aligned on the product vision and upcoming priorities.

Setting Up Cross-Team Refinement

In this initial layer, you’ll create a cross-team refinement meeting focused on high-level Sprint goals. This session should answer key questions about the broader product vision and Sprint objectives that affect all teams.

Goals of Cross-Team Refinement:Align on Sprint Goals: Ensure every team understands the broader Sprint goals and product vision.Clarify Upcoming Work: Outline high-level priorities, identifying work that each team will take on.Set Expectations: Establish expectations around deliverables, quality standards, and key outcomes.

Example: Imagine working on a feature that requires multiple teams’ contributions. In the cross-team refinement, you would discuss how this feature fits into the product vision, the user journey, and the value it delivers, so every team is on the same page.

Action Steps for Cross-Team Refinement:Plan the Agenda: Focus on Sprint goals, upcoming priorities, and any shared dependencies.Keep it High-Level: Discuss the “what” and “why” of upcoming work, but leave detailed discussions for each team’s session.Involve Key Stakeholders: Invite representatives from each team, stakeholders, and other decision-makers.

Pro Tip: Document key takeaways from this high-level session to serve as a reference for each team’s refinement.

Layer 2: Team-Specific Refinement

Once you’ve established the overarching goals, it’s time for each team to dive deeper into the “what” and “how” in their team-specific refinement sessions. This is where individual teams take the high-level guidance and translate it into actionable tasks for the Sprint.

Breaking Down the Work at the Team Level

Each team should hold their own refinement sessions to break down their specific tasks, focusing on the implementation details. These sessions allow each team to determine how they will contribute to the Sprint goals and address any dependencies or challenges unique to their work.

Objectives for Team Refinement:Detail the Tasks: Break down high-level items into stories or tasks with clear acceptance criteria.Identify Dependencies: Recognize any cross-team dependencies early on to avoid blockers.Define Success Criteria: Clarify the definition of “done” to maintain quality and alignment.

Advice: Attend each team’s refinement session as needed, but let the team take ownership of the tactical details. Trust their expertise and encourage collaboration within and between teams.

Action Steps for Team-Specific Refinement:Prioritize Stories: Based on the high-level Sprint goals, prioritize the stories and tasks relevant to each team.Establish Task Ownership: Assign ownership of tasks to specific team members to encourage accountability.Facilitate Dependency Management: If dependencies are identified, ensure there’s a clear plan for managing them.

Personal Tip: I’ve found that stepping back during team-specific refinements allows the teams to shine. They have the cross-functional skill sets to handle the tactics, freeing you to focus on the product vision.

Adopting a Strategic Mindset as a Product Owner

In a large-scale product setting, Product Owners need to adopt a more strategic role, enabling the team to focus on tactical details. This shift in focus from tactics to strategy empowers cross-functional teams and helps maintain a clear product vision.

Becoming a Strategic Product Owner

A Product Owner in a scaled environment should primarily:

Prioritize Product Vision: Keep the product’s vision and long-term goals front and center.Define Clear Objectives: Set clear objectives that align with the product vision, but let the teams determine the best path to reach them.Encourage Autonomy: Allow teams to handle tactical decisions while you maintain focus on the “big picture.”

Example from Experience: Early in my career, I found myself getting bogged down in day-to-day details. Over time, I learned the power of delegation and shifted to focus on strategic objectives. This change not only enhanced team morale but also drove more cohesive outcomes.

Benefits of a Strategic Focus:Improved Team Collaboration: Teams can work autonomously without frequent oversight.Clearer Decision-Making: High-level decisions are driven by product vision and user value, not short-term tasks.Higher Productivity: Product Owners can dedicate more time to refining the vision and engaging stakeholders. Wrapping Up: The Power of a Single Sprint Review

One of the essential principles in scaling Scrum is to have only one Sprint Review for the product at the end of each Sprint. Even with multiple teams contributing, a unified Sprint Review fosters alignment, enables comprehensive feedback, and promotes collaboration.

Why a Unified Sprint Review Matters:Ensures Product Cohesion: Multiple teams working on the same product means their work needs to be aligned. A single Sprint Review showcases the entire product increment.Facilitates Stakeholder Engagement: Stakeholders can view and provide feedback on the overall product, not just individual team contributions.Strengthens Team Collaboration: A shared Sprint Review encourages cross-team learning and highlights interdependencies.

Tip for Sprint Review Success: During the Sprint Review, focus on gathering actionable feedback rather than demonstrating every feature in detail. Highlight the value delivered and key updates to keep stakeholders engaged and informed.

How to Organize a Single Sprint Review:Prepare as a Team: Each team should bring forward their contributions, but the focus should be on the cohesive product.Highlight Key Updates: Select critical elements from the Sprint to present, emphasizing user value and business impact.Encourage Open Feedback: Allow stakeholders and team members to ask questions, provide feedback, and suggest improvements. Final Thoughts on Scaling Refinement and Sprint Reviews

When working with multiple teams on a single product, structured refinement layers and a unified Sprint Review are crucial. Remember to:

Use High-Level Refinement for cross-team alignment on Sprint goals.Empower Each Team’s Refinement for task breakdown and tactical execution.Embrace a Strategic Role as a Product Owner to guide vision and objectives without micromanaging.Conduct a Single Sprint Review to showcase the product increment cohesively and gather feedback.

Scaling Scrum effectively requires both a structured approach and a mindset shift. By following these strategies, you’ll empower teams to deliver high-quality results and keep the product moving forward in a unified direction.
