What is Backlog Grooming?
Also known as backlog refinement: the ongoing process of reviewing, clarifying, estimating, and prioritizing product backlog items. Ensures the team always has a ready, well-understood queue of upcoming work.
My perspective
In practice
Prevents the chaos of "surprise" stories in sprint planning. Well-groomed backlogs mean teams spend less time in planning meetings and more time delivering value. Done continuously, not as a big-bang event.
