CE719 ICT Systems Integration and Management Assignment 1: Information Quality
25th October 2021
In this assignment, you will practice how to use the attributes of information quality to assess different real-world scenarios.
The assignment consists of two parts:
• In Part A of the assignment, you will act as a lecturer who wants to select a coursebook for a new module CE919 Business Information System.
• In Part B, you will compare two websites of your choice and evaluate their address input functions using different postcodes.
When the assignment is finished, you will have to submit a single PDF file to https://faser.essex.ac.uk/
The deadline for submitting the assignment is 11:59:59 Friday 19th Novem- ber 2021.
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).
1. 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].
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].
