The short answer
A master board is one board where the key items from many boards live together — leadership visibility, cross-client capacity, or a control tower for operations. The reliable way to build one is to have the same items exist on both their home board and the master board, so the master updates itself. Copying items up creates drift; mirror columns can’t carry a real workflow (why).The pattern
- Teams keep their boards. Marketing works in the marketing board, each client has their client board — nothing changes for them.
- Create one master board with a group per team, per client, or per person, depending on the question the board should answer.
- Share the relevant items to it. With Same Item Multiple Boards, each item also lives on the master board — the same item, not a copy.
- Automate membership. Automation recipes like “when status changes to Active, share item to Master Board” keep the master current without anyone curating it. Unlink items when they close to keep the board lean.
Real examples
- “Who is overloaded this week?” — an agency running 30 client boards shares every active task to one workload board grouped by person. Capacity planning went from opening 30 boards to reading one.
- Executive rollup — department boards share only their key initiatives up to a leadership board. No Friday status-copying, no stale exec dashboard.
- Sprint control tower — items from several project boards appear in one delivery board with Kanban lanes built on their real status columns (possible because the columns aren’t mirrors).
Setup notes
- Column names and types must match between the home boards and the master board — use column mapping to preview and create missing columns in one click.
- Bringing in existing items? Share them in bulk with batch actions in manageable batches.
- Use the Item Locations column on the master board to see every board an item lives on and jump to it.
- Completed items can be unlinked automatically by status to free up plan quota.
