Definition:

Backlog Grooming is the process of reviewing, refining, and prioritizing items in the product backlog. The goal is to ensure the backlog remains relevant, clearly defined, and properly ordered so that the team can plan and execute work effectively.

Example:

During a Grooming session, the Product Owner and team might break down a large feature into smaller, more manageable user stories and clarify acceptance criteria to prepare the items for an upcoming sprint.
