We've turned from Scrum to the basic LeSS Framework for scaling Scrum beyond a single team.
In product Backlog Refinement article, 3 types of Refinement have been introduced which are as follows:
- Overall Product Backlog Refinement (
- Team-level Product Backlog Refinement
- Multi-team Product Backlog Refinement
At the LeSS meetings section of this page mentioned
4 hours duration for
Overall Product Backlog Refinement (PBR). But I couldn't see anything about the duration of the other two Refinements.
I'd like to know what are the Time-Boxes on a team and multi-team level Refinement?
