Greetings students,
Thank you for reading Tutorial Letter 103 (TL 103), which focuses on Assessment 2. Please take
note of the following important details:
Opens: Friday, 30 May 2025, at 08:00 AM
Due: Friday, 27 June 2025, at 08:00 PM
Total: 100 marks
Do not cheat! Plagiarism or academic dishonesty will not be tolerated. If you copy from other
students or submit work that is not your own, I will detect it, and a mark of zero will be awarded.
Your submission must be your own unique work – this is part of your learning journey in this
module. Before you start: Read the entire assessment carefully: Case, Question 1, Question 2,
Question 3, and Question 4. Begin immediately if you want to submit on time. Except for
Questions 1.1.1 and 3.1, your student number must be included in all entity names. For example,
if the entity name is STUDENTS, use: STUDENTS_39475964. Failure to include your student
number as required will result in zero marks for that specific question. Submission Instructions:
Submit your solution(s) as a single PDF file on the INF3703-25-Y site via myUNISA. Although the
case study is inspired by true events, all names, characters, and incidents have been
pseudonymised. Any identification of pseudonymised persons (living or deceased), places,
buildings, or products must not be inferred.
CASE
Table Mountain Shopping Centres (TMSC) are a chain of malls located across the Cape
Peninsula. The mall has been avoiding the use of automated pay stations to counter the negative
effect that rapid technological advances have on employment growth. That is, they prefer to use
the services of parking attendants (i.e., car guards) to help keep people employed amid the rush
by various industries to adopt technology. Parking attendants are formally employed and paid a
weekly wage by the Table Mountain Shopping Centres chain. To boost their weekly wage, parking
attendants rely on cash tips. While the mall does not use automated pay stations, the managers
acknowledge the advantages of having a cashless parking pay station and its associated
technologies. For example, if you arrive at a station, you wave your hand in front of a motion
sensor to initiate the issuing of a parking ticket. Motion sensors advance health safety by reducing
the risk of contracting a virus like COVID by preventing physical touch. Furthermore, sensors
installed at each parking space can detect the presence or absence of a vehicle; in the instance
where it detects that a parking space is not occupied, it communicates this information to the
parking station, which, in turn, prints the available parking space location ID (e.g., please park
your vehicle at parking space A25). Therefore, human parking attendants are not needed in the
presence of such advanced system (see Waldron-Curry, 2023).
To compete with these technological advantages, parking attendants use walkie-talkies to
coordinate the allocation of an available parking spot. However, the shopping centre management
observes that transaction technologies have been detrimental to cash tips. On the verge of the
4th industrial revolution, the phenomenon of physical cash that exchange hands has been
showing a significant decline. Needless to point out, nowadays it is convenient to pay for
purchases by simply swiping, inserting, or tapping your bank card. The managers furthermore
