Positions
A position is the job title inside a department: sales representative, support lead, accountant. Positions carry the default responsibilities you define, so structure does part of the managing for you.
Roles and permissions
Roles are the permission layer: owner, manager, member. Permissions are enforced by the server on every request — a member simply cannot reach what a manager sees, and the platform records the attempt if someone tries.
Who can change what
The owner can change the structure and roles at any time. Managers can manage within their department. Members do their own work. Every change is recorded in the audit log.
