Velocity is usually measured in story points, which represent the relative effort or size of user stories or tasks completed by a team during a sprint. It helps teams in planning and forecasting future work.

The "scope change" line in a Sprint Burndown Chart represents changes in the scope of work during the sprint. This could include additional tasks being added, existing tasks being removed, or modifications to existing tasks. It helps the team understand the impact of scope changes on sprint progress.

You can track the progress of a specific version or sprint in JIRA by using the Burndown Chart. This chart visually represents the amount of work completed versus the amount of work remaining over time, providing insight into the team's progress and velocity.

In JIRA, a "transition" in a workflow signifies the movement or transition of an issue or task from one status to another, reflecting its progress within the workflow structure.

Custom fields in JIRA allow you to capture additional information about issues beyond what is provided by default fields. Therefore, the correct option is "Information."

The "Definition of Done" in Scrum defines the criteria that must be met for a product increment to be considered complete and potentially shippable. It ensures that all work completed during a sprint meets the team's quality standards and the Definition of Done criteria agreed upon by the Scrum team.

In JQL, the "order by" clause is utilized to sort the search results based on specified criteria, ensuring the results are presented in a desired sequence. Filtering, grouping, and aggregating are not the primary functions of the "order by" clause in JQL.

In JIRA, to move an issue from one status to another, you need to perform a transition. Since the issue is currently in the "In Progress" status and needs to be moved to "Testing," the appropriate transition would be to transition the issue directly to the "Testing" status. Hence, the correct option is Transition to Testing.

JIRA is primarily a project management software used for tracking and managing tasks, issues, and projects. It is not a customer relationship management or any other type of software mentioned.

A JIRA workflow is a series of steps (statuses and transitions) that an issue goes through during its lifecycle within a project. It defines the process from creation to completion or resolution of an issue. Understanding JIRA workflows is fundamental for effective issue tracking and project management.

A project administrator in JIRA is primarily responsible for managing user permissions. This includes controlling who can access the project, what actions they can perform, and what information they can view or modify within the project. By managing permissions, the project administrator ensures that only authorized individuals have access to sensitive project data, maintaining security and confidentiality.

JIRA Automation can be used to send custom notifications by configuring automation rules to trigger based on specific events and conditions. Users can define actions within these rules to send notifications to relevant users or groups, ensuring timely communication and updates within the JIRA environment.
