Once an issue has been created, the user that's normally assigned to the issue will start working on it. Afterwards, the user can assign the issue further, for example, to QA staff for further verification.

There are many instances where an issue needs to be reassigned to a different user, for example, when the current assignee is unavailable or if issues are created with no specific assignee. Another example is where issues are assigned to different people at different stages of the workflow. For this reason, Jira allows users to reassign issues once they have been created.

Go through the following steps to assign an issue:

1. Browse to the issue you wish to assign.
2. Click on the Assign button in the Issue menu bar or press A on your keyboard (you can also use the in-line edit feature here). This will bring up the Assign dialog.
3. Select the new assignee for the issue and optionally add a comment to provide some information to the new assignee.
4. Click on the Assign button, as shown in the following screenshot:

Once this issue has been reassigned, its assignee's value will be updated to the new user. The new assignee will also receive a notification email, alerting them of the assignment. You can also unassign an issue this way by simply selecting the Unassigned option. Unassigned issues do not have an assignee and will not show up on anyone's list of active issues.
