When the technician accepts a work list, a permission slip corresponding to a specific device is entered in a service key inserted by the technician into a client. Then the service key is removed and inserted into a specific device to execute a field service operation. After the completion of the field service operation, the permission slip is closed and a service log is created and stored on a service database. An auditing system accesses the service data to track and monitor the service operation.
