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 attributes 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).

1. Choose two websites of your choice and test three postcodes (such
as shops on the Colchester high street), and use the attributes of information 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].
3. Sometimes a 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 [10 marks].
4. 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
[10 marks].
