QUESTION 1 [20]
In the business case, the project team must justify the needs driving Project Vision. You
suggested consulting Maslow’s hierarchy of needs (see Figure 1) to contextualise the
motivators.
1.1. Correlate the needs of Project Vision’s end-users to Maslow’s hierarchy of needs. (5
x 4)
Answer
Project Vision directly addresses several levels of Maslow’s hierarchy of needs for visually
impaired students like Noma. Firstly, at the physiological needs level, the project indirectly
ensures students can access essential services and university facilities, which contributes to
their ability to maintain daily routines necessary for health and well-being. Reliable
transportation through Bolt Vision enables them to attend classes and participate fully in
university life, reducing stress related to basic mobility.
Secondly, concerning safety needs, Project Vision is crucial in providing a secure
transportation option for visually impaired students. The trained drivers, obstacle detection
through TWO EYES, and real-time updates improve personal safety during travel. Students
are protected from getting lost, encountering obstacles, or facing physical dangers, and the
service’s design ensures that users feel safe and protected during commutes.
Thirdly, Project Vision contributes to belongingness and social needs. Visually impaired
students often face social exclusion due to mobility barriers. By enabling them to attend
campus activities, lectures, and social events more reliably, Bolt Vision fosters inclusion,
helping students feel part of the university community and maintain meaningful relationships
with peers and staff.
On the level of esteem needs, the system empowers visually impaired students by granting
them greater independence and control over their mobility. The ability to independently hail
rides, manage payments, and interact with drivers through TWO AUDIRE enhances
confidence, self-respect, and social status, reinforcing feelings of competence and autonomy.
Finally, at the level of self-actualisation, Project Vision supports students’ ambitions for
personal growth and educational attainment. With reliable access to campus and learning
, resources, students like Noma can pursue their academic goals without transportation
barriers, engage in innovative projects, and participate actively in shaping technology that
serves their community, enabling them to realise their full potential.
QUESTION 2 [30]
2.1. Why are the average working hours per month divided by 2? (2)
The average working hours per month are divided by two because the Project Manager is
working part-time on Project Vision, allocating only half of their available monthly hours to
this project. This ensures accurate cost estimation by reflecting that only 50% of the project
manager’s time is dedicated to the project over the ten-month period.
2.2. Calculate the WBS Level 2 total of the hardware that will be procured. (4)
Calculation:
• Air pods cost = 50 × R2,500 = R125,000
• Smart glasses cost = 50 × R4,000 = R200,000
• Total hardware cost = R125,000 + R200,000 = R325,000
Answer:
The WBS Level 2 total cost for hardware procurement is R325,000.
2.3.1. Calculate the total labour estimate. (2)
Calculation:
• AI developers: 1,920 hours × R160 = R307,200
• Project team: 1,600 hours × R120 = R192,000
• Total labour estimate = R307,200 + R192,000 = R499,200
Answer:
The total labour estimate for software development is R499,200.
2.3.2. Calculate the total function point estimate. (2)
Calculation:
Total function points = 345
