Hi, I have joined a new programme where there are 3 teams each set up with their own project in Jira. One team has a Scrum board point to its project issues and the others have created Kanban boards for their respective projects. The teams issues are often dependent on each other. A new requirement is broken down into work for each team and then each team lead creates the work for their team in their project. My (new) role in Product Owner for all three teams and I want a way to create my high level epics which i can then break into stories for the relevant teams. Can you recommend the best approach for this?
