Sometime Scrum events may took much less time than Scrum Guide prescribes. Is it a signal, that we did something wrong?
As usual, there is my thoughts on this topic for some clarification:
Daily Scrum. I think this is ok, if that event take less then 15 minutes. It's depend on team size. Smaller team - less time.
Sprint Planning. As I said in this question, in the beginning of projects (when Product Backlog is not yet refined well) this event took much more time for our team. But then (especially toward the end of projects) we spend much less time for planning, than Scrum Guide prescribes. Should it be a problem for us?
Sprint Review. My team never spent less time for that event, than Scrum Guide prescribe. But if it will happen, what it can signal about?
Sprint Retrospective. The same as Sprint Review. We always have what discuss with my team. But if it will happen, what it can signal about?
About Product Backlog refinement. The same as Sprint Planning. It took more than 10 percent of team capacity (I guess. I never calculated it exactly) in the beginning of projects and less in the ending. Is this ok?
