Most role-based permissions grant additional permissions by implication. That is, the permission grants not only the permission that its name indicates, it grants additional implied permissions.

For example, any permission that grant access to a particular type of object automatically includes (by implication) the UI permissions required to work with that object. Users that belong to roles that include the Manage Taxonomy permission, for instance, automatically receive the Use the Administration UI permission by implication.

The Manage Organizations permission is an example of another permission that grants additional permissions by implication. This permission, when given at the system-level, essentially implies all other role-based permissions. Consequently, a user with Manage Organizations permission at the system-level can manage virtually any object in any organization.
