On the seventh day of the Iteration, the team realizes that they will not complete 5 of the 13 Stories. The Product Owner (PO) says she cannot negotiate the scope of the remaining Stories any further. What is the PO's best course of action

- Communicate the status of the Iteration to all stakeholders.

Explanation:

The product owner is primarily responsible for representing the customer before the development team. They are responsible for managing the product backlog to ensure that it is updated and aligned with the priorities and vision of the product.

In the given situation, the best course of action for the product owner would be to 'communicate the actual status of the iteration to all the stakeholders' as hiding it may affect the standard of the product and customer requirements eventually. After expressing the status of the iteration, they together can reach a solution to this problem.
