# Organisation Structure

> How organisations, workspaces, and teams work in BlackMountain

BlackMountain uses a three-level hierarchy to organise your teams and resources:

## Hierarchy

```
Organisation
  └── Workspace
       └── Team
```

* **Organisation** -- The top-level entity representing your company or group. All resources, members, and settings live within an organisation.
* **Workspace** -- A subdivision within an organisation. Use workspaces to separate departments, projects, or business units.
* **Team** -- A group of members within a workspace. Teams can share assistants, folders, and other resources.

## Why This Structure?

This hierarchy supports enterprise use cases where multiple departments or project teams need their own spaces while remaining under a single organisation. It allows:

* Centralised member management at the organisation level
* Department-level separation through workspaces
* Team-level collaboration and resource sharing

## Navigating Between Contexts

Use the **Organisation Switcher** in the top-left header to switch between organisations, workspaces, and teams. The switcher shows your current context and lets you navigate the hierarchy quickly.
