On the seventh day of the iteration, the team realizes that they will not complete 5 of the 13 stories. the product owner says she cannot negotiate the scope of remaining stories any further. what is the team's best course of action?

First of all the team should excuse to the product owner for not being responsible and committed to the deadline.

Secondly, as they have completed the 8 stories, so they should revise and check the flaws in those stories and send to her.

Because when the product owner will check and happy with them, she will surely discuss the remaining stories with the team.

no. when the asker posts the question they can make a question worth what ever they think is a fair price. although it must be within the limit of the points they currently own. 5 is the minimum number of points a question can be worth. if a question is complicated or has lots of parts to it, it is better to make it worth more because more people will be more willing to answer.

hope this !
