  • known systems have been focused on business MDM and government MDM. Such systems are directed to the support and security services of mobile devices owned by a particular enterprise with a focus often on access to enterprise data and systems. In these systems, the managers make device control decisions imposed by entities providing the devices to users. The managers also determine the control policies and management services that apply to the devices.

Membership can take the form of, for example, employee/employer, service member and a unit of the Armed Forces, or an independent contractor relationship which are referred to as organizational relationships.
  • the management of devices is established by a policy control authority inputting data into the MDM system and policies are made obligatory to all of the members subscribing to the service - control of the device is mandatory and imposed by fiat.
