It took quite a lot of discussing and experimenting in order to get a UX workflow in to Jira that worked for us.
We wanted UX tickets to have their own workflow. How work gets done in UX, needed to represented the nature of UX – i.e. that it is a creative and fluid affair and that a lot of design work requires exploration and testing. The workflow is the minimal amount of steps required (basically: ready, in progress, review, done). However, the status changes inbetween each status allows for further testing.

The tickets can be either ‘UX work’ or ‘UI work’ or a design sprint or even a ‘test’.
