In Zephyr, you can create, edit, export and track defects. You do this on the Defect Tracking page by using the built-in issue tracking system, or, if your administrator has integrated Zephyr with a Jira instance, you can do this either on this page or in Jira. In this case, the data will be synchronized, and you will have the same values both in Zephyr and in Jira.
