Best practices

Rename user attributes with the name “Organization”. 

BlackBerry AtHoc

 provides an enterprise user attribute with this name.

Plan the promotion of attributes and alert folders:

Using enterprise attributes and alert folders is a good way to enforce consistency.
If more than one organization uses the same user attribute, the attribute should be promoted to the enterprise level.
If organizations use different values for the same user attribute, all values are promoted to the enterprise level.
Think about situations in which you need to alert the entire enterprise. What attributes do you need to target all users in an alert? These attributes should be promoted to the enterprise level.
Attributes that are for only one suborganizations should stay at the suborganization level.

Create end users and operators for suborganizations at the suborganization level, not the Enterprise level.

You can see all users from suborganizations from the enterprise organization so there is no reason to create any users at this level aside from Enterprise operators (operators that need to send alerts more than one suborganization).

Create a new enterprise organization rather than reuse a headquarters organization if there are existing users. Move the headquarters organization under the enterprise level.
