What two things should be done if the Product Owner is unavailable? (choose the best two answers)
In a permanent state of unavailability, a new Product Owner needs to be appointed. Development efforts without a Product Owner are not employing Scrum.
There should be a Product Owner team to allow a different person from that team to instantly take over the role of Product Owner.
Within the Sprint, the Development Team makes the best decisions possible to assure progress toward the Sprint Goal, re-aligning with the Product Owner once he/she is available again.
Development of functional requirements stops until the Product Owner is available again.
