Product backlog refinement (or grooming) is one of the activities in Scrum. This session is about how to do it in different scales.
In this session, we’ll explore the product backlog refinement practices from the situation of “a single person project”, to "a single scrum team", to "one PO with multiple teams", and to "8+ teams on one product."
The examples in the session are from real life organization. There will also be a simple simulation to help the audience to practice.
Definition of PBR in Scrum or Large Scale Scrum:
[Ongoing] Product Backlog Refinement (PBR) is needed within each Sprint to refine items to be ready for future Sprints. Key activities of PBR are (1) splitting big items, (2) detailing items until ready, and (3) estimating. In the spirit of empirical process control, Scrum does not say how to do PBR, though suggests that the Team spend no more than 10% of their Sprint capacity on it. It usually happens “mid-Sprint.” (https://less.works/less/framework/product-backlog-refinement.html)
