I have just started as PMO Coordinator of several teams. All teams add sub-tasks to stories/requirements, and they do all this in Jira (create requirements/stories + DEV team add sub-tasks), and all of them do that their own way, without following any specific format for user story creation, with in many cases lead to confusion as requirements aro not clearly exposed.
So I wanted to use Confluence as a home for our stories. But my question is, how can I add sub-tasks to this stories? Is it possible to do so in Confluence? Or do you have any other ideas regarding how to unify requirements/stories creation across all teams? I just thought of confluence since in my previous jobs I used it and it is a good way of creating clear stories.
