Team & Roles
Project team access
The per-project access layer on top of organisation roles.
Organisation role (Owner/Admin/Member/Billing) is one axis of access. Project team membership is a second, separate axis that controls the kanban board specifically: only people on a project's team (plus Owners and Admins, who always have access) can see or time that project's board.
This means a Member who's part of your organisation might still not see a particular project's board until they're explicitly added to its team — see Project teams for how that's managed.
