Manage Permissions
* 
Because administrators can see all assets in their organization, they will not appear in the user list when managing permissions for assets and procedures.
You can manage permissions for editing procedures, assets, and published procedures. For more information, see the following topics:
• Manage Edit Permissions on a Procedure
• Manage Folder Permissions
• Manage Asset Permissions
