As a BI practioner
I want to understand when I can start backlog grooming
So that I don’t start it to early and cause un-required rework, or leave it to late and not be ready to start the sprints

[[curate the known sotries]]

[[2 hours session in week 2 and week 3]]

[[fil up sprint -1 and sprint -2, typically 80% full]]

[[goal is to make sprint planning shorter and easier because a lot of the planning work has already been done]]

[[deals with surprises found during the sprint]]

[[big decision to move stories into backlog of the current sprint]]

[[sprint planning in week 1]]

[[can deal with epics, users stories, developer stories, but developer sotries are typically done during sprint planning]]

[[can grrom new epics if there is a change of vision in the next sprint]]
