Abstract: Information associated with an organization chart is stored in a personnel database. An organization chart processing program reads out organization chart information from the personnel database and displays the organization chart on the screen of a display device. When a user designates "move" or the like to an employee or a department/section on the organization chart through an input unit, an organization chart editing processing program executes this designation and changes the organization chart. The change contents are reflected on the personnel database. An official announcement processing program forms an official announcement record for an employee subjected to personnel changes upon the change in organization chart and stores the official announcement record in an official announcement history file. This official announcement record is printed out as a written official announcement for personnel changes through a printer.
