Apologies for the very late response to this! I hadn’t logged back on to Medium for a while as I’ve been really busy with a large project launch.
In terms of getting designers extended within the dev workflow — this has always been a tricky area for us. However, after the status: “In Progress”, we have a “Ready for Code Review” status before we pass it on to test. We have trialled adding in a “Ready for Design Review” following code review, but this is an optional status in the workflow because not all features/stories require design review. If it doesn’t, or if design has passed, the ticket gets dragged to “Ready for QA”.
Let me know if you have trialled using another format or need any other advice.
