While sizing a user story in planning poker, one team member believes the user story should be 8 points. Another believes the story should be 2 points.
What should the scrum master do?
A.
Determine the average of the two estimates and assign that amount.
B.
Ask the product owner to rewrite the story so the final estimate can be agreed upon.
C.
Consult the lessons learned for insight into the correct estimate.
D.
Select the junior member's estimate since they will most likely be doing the work.
Significant estimation discrepancies often indicate a lack of clarity. The story may be ambiguous or too broad. In agile practices, the team should ask the product owner to refine the story so it can be better understood and estimated with greater accuracy.
A (averaging) is not an agile practice.
C may be helpful but not sufficient in real time.
D is arbitrary and ignores team consensus.
B supports agile practices like backlog refinement.
