What architecture is recommended to use and visualise? On which level is best to use assignees and teams?
Thank you for your response! Do you have any best practice for managing cross-team issues? I found that one issue can only be assigned to one team which is fine most of the cases with stories and tasks but Epics are most often are cross-team endeavours. I was thinking to trick it with labels but it only works on plan view, program view does not manage labels. Do you have any suggestion on this? Thanks a lot!
"Best practice" is what works best for you. I can't tell you what to do without a detailed understanding of your desired processes, reporting needs, procedures and what you're trying to achieve.
