Creating a custom field in Jira can be a great way to track additional information related to your projects and tasks. This can be especially useful if you need to track data that is not already available in the default Jira fields. For example, you may want to create a custom field to track the estimated cost of a project, or the priority level of a task. By creating a custom field, you can easily add this information to your Jira projects and tasks, making it easier to track and manage your work.
