Zephyr provides support for 2 defect tracking/wiki/spaces/ZEE50/pages/77725932integrations as a defect tracking tool:

• Zephyr Internal Defect Tracking System
• JIRA

As an Administrator, under System Setup, you can select the Defect Tracking section to expand the window for adding a defect tracking system to Zephyr. Pick carefully, as switching to another Defect Tracking System at a later stage is not recommended.
 

 
Regardless of which system is selected, Zephyr provides the user with a Defect Tracking module that allows them to file new defects, view existing ones, modify them and report on them. This interface remains the same for both options.

No Defect Tracking Integration

Picking the None option will disable defect tracking and remove the Defect Tracking icons from the various Desktops. Once a Defect Tracking System is selected the user should logout and log back into their Desktop again for it to become effective.
