    1. Refinement usually consumes no more than 10% of the capacity of the team. 

      It used to give me a good reason to point to the Scrum Guide when the team was annoyed by the number of refinement hours during a sprint.

      With more experience, it becomes clear that the number of refinement hours spent should not depend on the Scrum Guide but on the readiness of work. A better measure, and this differs from team to team, is how many stories shall be ready at all times? One to three sprints worth of ready work? At least enough work should be ready before Sprint Planning, so that the actual sprint delivers done work (and not more refinement work, only.)

      Refinement hours spent also depend on how predictable the work is on the Product Owner’s roadmap and if there is a need to do first iterations of refinement on future releases, months away to have a very high level estimate of effort.

      Opinions?
