Have you been told that you should monitor the health of your team by means of the so-called Cycle Time? And that the Jira Control Chart can help you with that?
It's not always the case if you do this in a Scrum Team, is it?

In this talk, I will demonstrate that you really can learn something about the team health if you look at how long its tasks take to complete, but you need to dig a bit deeper. And once you do that, you will understand what is the difference between Kanban and Scrum, that a Kanban metric needs a bit of a translation before it is useful in a Scrum environment, and that Joel Spolsky knew this already 20 years ago.
