Team Expertise
The Scrum Team's combined skills and know-how used to interpret user stories and their tasks in the sprint backlog and produce the final deliverables. This capability is applied to judge what inputs, resources, and effort are needed to carry out the planned work.
Key Points
- Represents the cross-functional knowledge the team brings to understand and implement backlog items.
- Used during planning and refinement to identify required inputs, dependencies, and realistic estimates.
- Directly influences task breakdown, sequencing, and the quality of the increment.
- Grows over time through learning, collaboration, and continuous improvement.
Example
During Sprint Planning, a Scrum Team reviews a payment feature user story. By leveraging their expertise, they determine they need PCI-compliant libraries, test credit card data, access to a third-party API, and security reviews. Their combined knowledge refines the acceptance criteria, splits tasks, identifies risks, and sets a realistic estimate for completing the feature within the sprint.
