I am tagging Jira issues with the specific modules or features they are related to. The same set of tags are applied to Zephyr test cases, and the goal is to be able to look up the relevant test cases based on the tags used.
Hi @Asgeir Enersen,
I would suggest using Epics instead of Tags, as what you have described above would fit the use of Epics to capture issues that relate to a module or feature.
This would give you access to a few other features that are built into JIRA; such as Epic Reports, Epics section on Boards to easily filter, etc.
Since Zephyr's Test Case screen can be configured you can add Epic Link to the creation screen of the relevant Test issue type.
Hope this helps
