Question

Q.No.3. A filling station (gas station) is to be set up for fully automated operation. Drivers swipe their credit card through a reader connected to the pump; the card is verified by communication with a credit company computer, and a fuel limit is established. The driver may then take the fuel required. When fuel delivery is complete and the pump hose is returned to its holster, the driver's credit card account is debited with the cost of the fuel taken. The credit card is returned after debiting. If the card is invalid, the pump returns it before fuel is dispensed. As a software developer if you have to develop a software for the above given scenario, Suggest five possible problems that could arise if a you does not develop effective configuration management policies and processes for your software.

Answer 1

Answer:

Following are the 5 problems, that can arise in this scenario:

Explanation:

• When the driver swipes its credit or debit card, its connection with both the card company could not be formed due to the poor or ineffective development, therefore the driver may not put any fuel from its vehicle.  
• It still wants to spend energy even after the card is read as incorrect.  
• So, its total price to just be debited from the credit or debit card shall be much more and less than the real cost as well as the deduction of both the fuel should be overestimated.  
• Its information may not adjust when a driver uses its device because the next driver could no matter how long only use the device.
• Its fuel limit to also be established when the vehicle has stopped its card would be faulty as well as a certain restriction would not cause its device to be misused.
