Backlog Refinement: How Scrum Teams Avoid Sprint Planning Surprises
Backlog refinement is one of Scrum’s most overlooked practices—and one of the most important. In this Scrum Foundations lesson, Mike Cohn walks through how Product Owners and developers work together to make sure the top of the product backlog is clear, understood, and ready before sprint planning ever begins.
You’ll see how refinement helps teams surface open questions early, reduce sprint-planning churn, and avoid the painful moment of realizing a “top priority” item can’t actually be worked on yet. Mike also explains the tradeoffs between involving the whole team vs. a subset, why refinement is a checkpoint rather than a full design session, and why your team should stay within the “10% rule” to avoid over-analyzing future work.
If you’ve ever had a sprint fall apart because key details were missing or unanswered, this lesson will show you how to build a healthier, smoother flow from backlog → sprint.
