Question 4
Read each case study carefully and answer all the questions.
4.1 A university decided to outsource its HVAC (heating, ventilation, and air conditioning) maintenance
to a third-party provider in an effort to reduce costs. The university was able to achieve a 15% cost
reduction in the first year. However, during the same period, student complaints about
temperature issues in the dormitories and classrooms increased by 30%. The outsourcing provider
was meeting the technical requirements of the contract, but their response t imes were slower than
the in-house team they had replaced.
a) What could the university have done differently in the contracting process to avoid this
situation?
(4)
b} How could the university work with the outsourcing provider to improve response times and
Student satisfaction?

4.2 A corporate office building was struggling with frequent and costly equipment failures . An analysis
of the maintenance budget revealed that 90% of the funds were being spent on reactive repairs,
with only 10% allocated to preventive maintenance . This reactive approach to maintenance was
not only expensive but also resulted in significant disruption to the building's occupants.
