Once the Sprint Planning event is over, the Sprint backlog is committed and closed. No more changes to the Sprint commitment after that…
We’ve touched upon this point in previous posts but it is still a normal misconception after the Planning session. The team is not committed to the scope of tickets or the quantity of Story Points. The team commits to achieving a goal.
This is a completely different mindset from what we are used to, but it’s a shift that we all must do. Output-focused development must stop. Billing hours and delivering lines of code means very little if you are not achieving your goals. If you are not delivering value to your customer.

The scope is never final and it’s never closed.
