Task and Correspondence Management is fully ad-hoc workflow engine that is being fully identified by the user who initiates it by selecting user or group from the organization structure tree which shows all groups and users. This workflow means the process of managing the daily tasks in the organization and to reduce use of paper versions of these tasks. This procedure is built based on the organizational structure and hierarchy of the organization, which allows navigating through the full tree of the hierarchy from the top level down to the lower levels. The communication between users and groups is controlled by predefined rules that specify which actions can be performed according to the user level in the hierarchy.
