What is Product Owner work that a Product Owner might delegate?

The product owner is one of the technical scrum roles. The owner of the product (product owner) is the one who makes the customer's decisions. Your responsibility is the value of the product. In order to simplify communication and decision-making, it is necessary that this role falls to a single person. g

Explanation:

For the project to have a chance of success, the entire organization must respect the decisions of the Product Owner. No one, not even the CEO, should allow such decisions to be invalidated, and no one should tell the development team what to develop and deliver, except for the Product Owner, who establishes and orders the elements of the Product Backlog. The Product Owner's decisions may be influenced by others, but it is he who will have the last word.

The Product Owner may delegate part of his responsibilities (such as preparing the list of items in the Product Backlog to the development team), but it will remain his responsibility.
