ISY2001 – Case Study Assignment
Released in Week 05 – Due in session 11
Type: Individual assignment
Weighting: 20%Human Computer Interaction
DUE: End of week 11
Submission method: Turnitin on Moodle
Objective
This case study assignment allows students to understand and analyse user
requirements and design a simple system for a small business organisation.
System Requirements
FastCabs is a newly created taxi service company that provides online booking for
clients in the state of NSW.
FastCabs has considered developing a simple website for an online booking System
with the capability to enable clients access from their mobile devices and to book for
a trip. At the time of their first booking, clients should be able to enter their details
into an online form, along with their credit card details. However, clients can also
have an account with FastCabs and for any subsequent bookings, they can log in to
their own account and make a booking for a taxi. They need to be able to enter their
trip origin and destination. The system will give them an estimate of cost according to
their trip description.
Assuming you have been assigned to design and develop the system for FastCabs.
You are given three weeks to come up with a blueprint of the system design and
present the design to a team of consultants. The online booking System should be able
to perform a number of activities such as adding or creating a new customer, checking
for available taxis and drivers in the area requested by the customer, calculating cost
of trip, issuing online ticket or receipt and processing all bookings transactions. You
may add any other possible functions that you deem necessary for this system to
function in this business case.
Task
You are required to design a system that can perform the above activities and
maintain a database containing data relevant to those activities. Carry out “process
modelling” and “data modelling” to achieve this purpose.
Your tasks in this project include:
– Provide a justification of why this system needs to be developed and ensure that
you are professionally convincing to senior management.
– Provide a description of the business case and justification about the business
benefits from implementing this system.
– Describe the project scope and provide a brief cost and schedule analysis.

– Identify the major functions in the system that will be required in order to meet the
business needs.
– Conduct the TCO of this system in Excel; add your full name and student ID in
Excel in row 1. Embed the TCO part from Excel into the Word document, which is
your assignment file. Ask the teacher to show you how to embed this if you are not
sure.
– Develop data flow diagram (DFD level 0 and Context Diagram with at least 3
different processes).
– Prepare entity relationship diagram, to model the data requirement relevant to
this system.
– Create 3 screen interfaces a (main menu, an input screen and the monthly sales
report) that will be used in the system designed by your group.
The marking will be based on the design; it is not necessary to implement the system.
