Discussion on IRC: https://chatlogs.metabrainz.org/brainzbot/metabrainz/msg/4014166/

Chhavi summed it up as such:

We basically want a different workflow for all the "Design" tickets. (Please name them Design and not UX, design will keep it open for all kinds of issues that we might face)

Workflow

Needs Decision: When someone opens up a ticket or when someone just wants a design opinion on what they are doing. Or when they don't know what to label/workflow a ticket
Needs Mockup:
Needs Mockup Review: Once we have a mockup, community feedback on it
Needs Templating changes: If the tickets require just some front-end changes. Additional design support like logo, icons, fonts
Needs Server code changes

Labels
UX: the user flow isn't good
UI: the user flow makes sense, interface needs work
Branding: for social media, presentations and other outreach work
