The screencast below explains, how different teams can layout their Kanban board, without changing the default process template statuses "New", "Active", "Resolved", "Closed"
Team A (less columns, then statuses)
Backlog | Active | Done
Team B (more columns, then statuses)
Backlog | UAT | Development | Code Review | Test | Done
Because both Kanban boards use the same statuses under the covers, queries and reports can span multiple teams.
