Once the sprint is over, the next step is to refine the product backlog. During this process, new user stories are added to the product backlog and unnecessary user stories are removed from it. User stories' priorities can be changed by the product owner if required.

There is no doubt that the Scrum methodology helps us to implement projects quickly. Larger projects can be divided into multiple sprints. It is very flexible in terms of how easily it accommodates new changes. For example, if stakeholders request a new feature, a product owner can easily add them to the product backlog. But sometimes, this becomes a risk for the project when stakeholders keep requesting new functionalities.
