At any point, the user can use the system functions defined for this application to return to the main menu (POPTOP); display a screen that supplies the valid responses for the current function (HELP); or return to the previous function (TOP).
Before proceeding to the next step in the design and development of the application, the flowchart should be reviewed with end users and modified as necessary.
The following diagram illustrates the partial structuring of a sample management information system. The circles in the flowchart represent the application responses and the rectangles represent the functions. Within each circle is the response code and control key that will be defined to initiate the given function (for example, SKL/PF3 will initiate the display of information on employee skills). The system functions to be used in this application (that is, HELP, TOP, and POPTOP) are indicated.
