A team using Scrum consistently fails to complete all planned work in a sprint. What should the Scrum Master do first?
Smaller stories enable better estimation and completion within the sprint.
Why this answer
Option B is correct because breaking stories into smaller pieces helps the team better estimate and complete work within the sprint. Option A is wrong because increasing sprint length reduces feedback frequency. Option C is wrong because adding members doesn't fix sizing issues.
Option D is wrong because the Product Owner should attend daily stand-ups.
