Global Permissions in JIRA are used to control access to system-wide settings such as user management, application access, and administrative functions.

Project roles in JIRA are collections of users who have common access rights and permissions within a specific project. They help in managing and controlling access to project resources and functionalities based on user roles.

The "jira-users" group in JIRA is significant because it includes all users with access to the JIRA instance. Users added to this group typically have basic permissions to interact with projects and issues within JIRA. This group is fundamental for granting initial access to new users and ensuring that they can start using JIRA effectively. It is not exclusive to administrators or users with specific license types; rather, it encompasses all users in the JIRA environment.

To automate the creation of sub-tasks for specific issue types in JIRA, you would utilize JIRA Automation Rules. With JIRA Automation Rules, you can define triggers, conditions, and actions to automatically create sub-tasks when certain criteria are met, such as specific issue types. By configuring automation rules in JIRA, you can streamline the process of creating sub-tasks and ensure consistency in your workflow, ultimately improving efficiency in issue management.

Users can review and rate JIRA plugins and add-ons on the Atlassian Marketplace. The Atlassian Marketplace serves as a centralized platform where users can find, evaluate, and acquire plugins and add-ons for various Atlassian products, including JIRA.

Permission schemes in JIRA allow project administrators to control access to various project actions, such as creating, editing, or transitioning issues. By assigning appropriate permission schemes, administrators can ensure that only authorized users can perform specific actions within the project.

In JIRA, typical reasons for transitioning an issue from one status to another include completion of a task, need for further review, change in priority, and various other workflow-related actions. All of these options are valid reasons for transitioning an issue.

Velocity, in the context of Agile reporting, represents the amount of work a team can complete in a sprint based on historical data. It helps teams estimate their capacity and plan future sprints effectively. In JIRA, velocity is calculated by summing up the estimation points of all completed user stories or tasks in a sprint.

JIRA workflows utilize Post Functions to execute actions automatically after transitions. These functions can range from sending notifications to updating fields or triggering external processes, enhancing workflow automation and streamlining issue management processes.

In JIRA, "Edit" allows users to modify the details of an issue, such as the summary, description, assignee, etc., without changing its workflow status. On the other hand, "Transition" is used to change the workflow status of an issue, moving it from one status to another in the workflow. This typically represents progress in the issue's lifecycle, such as from "Open" to "In Progress" or from "In Progress" to "Resolved".

Following consistent naming conventions for JIRA issues is crucial because it aids in searchability and organization. Consistent naming makes it easier for team members to locate specific issues quickly, fosters better communication, and enhances overall project management efficiency.

The primary purpose of a product backlog in Agile is to prioritize and manage requirements. It serves as a dynamic document that captures all the features, enhancements, and fixes that need to be implemented in the product. Prioritization ensures that the team works on the most valuable items first.
