In Jira Software it is possible to modify workflow such that tasks cannot be marked done unless all subtasks are also done (ref: https://support.atlassian.com/jira-cloud-administration/docs/configure-sub-tasks/)
I can't see a way to do this within Jira Work Management within the standard Team project transition settings.
Does anyone know if it is possible to create this dependency on subtasks in JWM?
Hi @John Howell and welcome to the community!
I have accomplished this through use of automation and a workflow validator.
We use an automation rule to flag/unflag the parent task based upon the state of its sub-tasks. In the example below, the rule triggers on creation/transition and branches into the parent task twice.
Now, in your workflow, you'll want to use the regular expression check against the Flag field
