Part A: Coursebook Selection [50 marks]
Imagine that you are a lecturer at the University of Essex and you are assigned a new module:
CE919 Business Information Systems. As a part of the new course development, you need to decide which coursebook to use for the module.
1. When you select the coursebook what kind of
information quality at- tributes are
important for your decision making and explain why [20 marks].
You should use the attributes of information quality
listed in Table
1.1 of our coursebook to guide you. Choose attributes you think are suitable for your decision
making and explain
why they are important.
2. Choose an online bookstore (e.g. Amazon,
Waterstones) to search for the
coursebooks available and analyse three coursebooks
of your choice using the attributes
you cheesed in the first step. Make
your selection of the textbook and
explain why you choose that book [30 marks].
You can use screenshots to help you visualise the comparison.
Part B: Postcode
Address Finder [50 marks]
Address entering is arguably one of the
most frequently used functions in modern
information systems. Whether you are purchasing a product online, booking
a ticket or make a job application, you need to fill in your address.
In UK, the postcode address finder has been used to make quick address entering. Online retailers and postal
services such as Jonh Lewis, Wilko and Royal
Mail all heavily use the postcode address finder in their daily business. In this assignment, you are going to
compare the postcode address finders used by different websites. Please note you are expected
to use the postcode to find the address, do not attempt to enter the address manually.
Hint: Most online retailers have guest checkout. You don’t need to be a registered user to test their postcode
address finder. You can put a random product
in the basket and use the guest checkout to access their delivery page where
the postcode address finder is commonly located. Alternatively, you could
choose postal service websites, such as Royal Mail’s find an address page (https://www.royalmail.com/find-a-postcode).
Choose two websites of your choice
and test three postcodes (such as shops on
the Colchester high street), and use the attributes of in- formation quality to compare the two
postcode address finders. You should discuss both the advantages and
disadvantages of the different systems [20 marks].
You are expected to use the screenshot
to support your comparisons.
2. The address of the Universities are usually more
complex. Take the University of Essex as an example,
most of the university buildings
and student accommodations share a single postcode (CO4 3SQ). Let’s check how the two systems handling the
university postcode. Do they return
the same results? How is the quality
of the information they returned [10 marks].
postcode may cover many addresses, especially if you live in a flat in a tower block. In such cases, finding the
address using postcodes can be
painful. Suppose you want to find the address ”201 Westcliffe Apartments, 1 South Wharf Road, London, W2 1JB”. How easy
can you find the address? Which system works better and what can be improved
It is not
uncommon the postcode entered by the customer may be incorrect. A robust system should be able to handle
such cases to some extend. Suppose you want to find the address
”137 Chesterton Road, Cambridge, CB4 1AA”. But you thought the
postcode is CO4 1AA. With this wrong postcode, do the systems still be able
to find your address? Which
system handles better
and what can be improved
