Section C: Practical Questions
[37 marks]
Question 1: Consider the following summary of issues reported in a travel agency. Identify the main issue
and construct a cause effect diagram for the traveling agency.
[7 marks]
A travel agency has recently lost several medium-sized and large corporate
customers due to complaints about poor customer service. The management team
of the travel agency decided to appoint a team of analysts to address this problem.
The team gathered data by conducting interviews and surveys with current and past
corporate customers and also by gathering customer feedback data that the travel
agency has recorded over time. About 2 % of customers complained about errors
that had been made in their bookings. In one occasion, a customer had requested a
change to a flight booking. The travel agent wrote an e-mail to the customer
suggesting that the change had been made and attached a modified travel itinerary.
However, it later turned out that the modified booking had not been confirmed in
the flight reservation system. As a result, the customer was not allowed to board
the flight and this led to a series of severe inconveniences for the customer. Similar
problems had occurred when booking a flight initially: the customer had asked for
certain dates, but the flight tickets had been issued for different dates. Additionally,
customers complained of the long times it took to get responses to their requests
for quotes and itineraries. In most cases, employees of the travel agency replied to
requests for quotes within 2-4 working hours, but in the case of some complicated
itinerary requests (about 10 % of the requests), it took them up to 2 days. Finally,
about 5 % of customers also complained that the travel agents did not find the best
flight connections and prices for them. These customers essentially stated that they
had found better itineraries and prices on the Web by searching by themselves.
