Abstract: A system manages resources among groups of workers that are connected to one another through a network. The system maintains the security of the resources and improves the operations of the groups. Each group manages the rights to use resources such as windows, objects, and data belonging to the group. Each group is allowed to use only resources whose rights to use are allocated to the group. The groups may exchange the resources among them through a job monitor (2). The job monitor automatically handles the rights to use the resources among the groups according to the working conditions of the groups, procedures, and a job definition form (11). The groups independently and cooperatively carry out jobs. The system employs telephones and pagers to access the members of the groups if they are absent from predetermined locations, to improve the operations of each group.
