I have a question for you guys. Say, you're given a task as an item in a product backlog. Say, you have a deliverable that's due the following day. If you're behind on the task compared to when you made your estimates, what do you do about it? Does it make you anxious knowing your behind schedule? How do you deal with this? Do you tell the scrum master or the product owner?
I would usually relay that information to the scrum master during the daily scrum meeting. As soon as you know you're behind you should inform the scrum master so he can either get someone to help you (maybe someone else is ahead of schedule and has bandwidth to help), determine whether overtime is needed, or if it's an impediment outside of your team's control then the backlog item needs to be deferred he can provide rationale to stakeholders.
