Global permissions in JIRA apply to the entire instance and are set by JIRA administrators.

The Scrum Master facilitates the process, while the development team contributes to refining and estimating backlog items.

Story Points in Agile methodologies serve as a relative estimation of the effort required to complete a user story. They help teams to plan their work more accurately by considering the complexity, risk, and uncertainty involved in each task. This estimation helps in prioritizing and scheduling tasks during sprint planning.
