We're on Jira Cloud Premium. A larger team works in one software project, and within it we have smaller sub-teams. Each sub-team would like its own velocity, burndown, and sprint report — scoped to just their work — while we keep a single cross-team view (we already use Plans / Advanced Roadmaps for the roll-up).
What I've found so far:
• The project is team-managed, so it has a single board — I can't add a second board scoped to a sub-team.
• Board and backlog filters (assignee, labels, custom filters) only filter the view, not the reports.
• The velocity chart, sprint burndown, and sprint report are board/sprint-scoped and can't be narrowed to a sub-team.
Given that, what does Atlassian recommend for this situation? Specifically:
1. Is the recommended pattern to give each sub-team its own team-managed project (so each gets its own board, sprints, and reports) with Plans rolling them up — or to move to a company-managed project with one board per sub-team, or something else?
2. Does the answer depend on whether each sub-team runs its own sprints vs sharing one team-wide sprint? If sub-teams share a sprint, is there a supported way to get per-sub-team velocity/burndown, or is the team-level number the only meaningful one?
3. If splitting or migrating is the recommendation, what are the main tradeoffs and gotchas to plan for (sprint history, components, custom fields, the estimation field)?
We're trying to keep the setup as simple as possible and avoid unnecessary structure or paid add-ons if native Jira can handle it. Thanks!
