Example Two:
Suppose instead, though, that the Scrum Master for this team announces they’ve selected only 11 points of work. They might in that case ask themselves why they were making the work so hard during Sprint Planning as compared to when they’d earlier estimated the same items in Story Points.
For example, this may reveal that during sprint planning they’d identified work they’d earlier not thought about, or perhaps had explicitly assumed would not be part of a given story. Or they may discover that the story really is harder than they’d thought when assigning points to it.
Either way, knowing they’d selected 11 yet averaged 20 will help the team know they’ve selected an appropriate amount of work or perhaps make a change to bring more.
