Good afternoon, SCRUM community!
Need your advise.
I recently came across an issue stated in a header - seemingly, the refinement work is done by development team, since they drill down into the backlog items and slice and dice them to understand how they can implement. On the other hand, product owner provides the information and must accept the outcome, since she/he is the one and only who is entitled to do that.
So, ist it the effort of the whole Scrum team? (Scrum Muster also lurking somewhere in the picture :-)
