Unable to finish all open tasks by deadline
What to do if I am not able to finish all open tasks by deadline, I am not talking in Sprint scope. Should I finish most of the relevant tasks or finish 70% all open tasks?
@Ismail, I am not sure if I understand your question. Since you state that you are "not talking in Sprint scope", I am confused what tasks you would be asking about.
I am also not sure about the "by deadline" statement. Are you talking about the Sprint boundaries or by some larger deadline being set on the delivery of a feature/component by someone outside of the Scrum Team?
If you could clarify your question I would bet that you will get multiple answers from which you can form your own opinion.
Ismail, have you reached out to others on your Development Team in a timely manner so that they can assist with moving the items to completion?
