Exhibit 6.3
Following is the narrative for the Check-out Equipment event. Use it to create a Primitive
Data Flow Diagram.
The employee enters an Employee ID which the system validates.
If the employee is found to be active, the system prompts for an
Equipment ID. The employee enters the Equipment ID of the
equipment s/he requires and the system checks that it is valid. It
also checks whether the employee is qualified to operate the
equipment based on the skill classification, and whether the
requested piece of equipment is in stock.
If the employee and equipment ID are valid, available, and not
restricted, a check-out transaction is recorded. The employee is
provided with a receipt detailing the check-out. The depot staff is
notified of the equipment location so they can physically retrieve it
from inventory. This ends the Check-out Equipment event diagram.
NOTE: Once the equipment is handed to the employee, another
event, the Confirm Equipment Check-out, will confirm that the
inventory has been physically reduced.
