Hello community,
I stumbled over the Scrum framework (see here) and would like to clarify that illustration since, in my opinion, it contains an error leading to a confusion of Scrum novices.
To me, the arrows within the diagram illustrate some kind of "leads to" or "is input to" relationship. For instance, the (groomed) Product Backlog "is input" to the Sprint Planning activity, which "leads to" the Sprint Backlog, etc.
