Suppose you are responsible for the design and development of a computer system to control an amusement park ride.

Suppose you are responsible for the design and development of a computer system to control an amusement park ride. Sensors in the seats will determine which seats are occupied, so the software can consider weight and balance. The system will control the speed and duration of the ride. The amusement park wants a system where, once the ride starts, a person is not needed to operate it. List 5 important things that you can or should do to ensure the safety of the system. Consider all aspects of development, technical issues and operating instructions. (1.5 Marks)
At many hospitals, doctors enter orders for prescription drugs for their patients into a computer system. Such systems eliminate errors from reading doctors’ handwriting and automatically check for conflicts with other medicines the patient is taking. On one system, when another doctor used the same terminal after the previous doctor neglected to log out, the system assigned drugs ordered by the second doctor to the first doctor’s patient. Describe 5 features that such systems could include to reduce this kind of error. (1.5 Marks)
Consider the following scenario. A state’s highway patrol keeps records of stolen cars in its computer system. There is no routine process for updating records when stolen cars are recovered. The system still listed a car as stolen a few years after it had been recovered and the owner sold it. A highway patrol officer shot and killed the new owner of the car during a traffic stop. The officer thought the car was stolen and that the driver was acting suspiciously. An investigation concluded that the officer “acted in good faith.” To what extent should the error in the database affect the family’s wrongful-death lawsuit against the highway patrol? Suggest 5 features the database should have that might prevent such incidents.
