Section C: Practical Questions
[30 Marks]
Question 1: Consider the following summary of issues reported by a travel agency. Identify the main
issue and construct a cause-effect diagram for the travelling agency.
[10 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.
Question 2: For each of the graphical notations shown below, state the name and its purpose in the
business process modelling project.
