2.  Dr David Upsdell, the newly hired enterprise architect at DRNZ, claims,  “data is our most important asset, because all our recommendations to  clients are derived from collecting, storing, and processing data through the activities of the drones. We have solid plans to secure that data” .

These plans include,

.      how to restore our backups after major catastrophes (like major earthquakes or volcano eruptions);

.      how to restore the data repositories have them fully operational within

2 hours of a catastrophe to continue uninterrupted service to DRNZ clients.

SECTION B:

SHORT ANSWER QUESTIONS

Refer to the Exam Case at the end of this booklet to answer ALL questions in this section. Question 21

A typical shopping process on the ‘DRNZ’ mobile app is described below:

i.       The customer taps on the “Sales Catalogue” button on the app. A list of all the individual items for sale is displayed.

ii.      The customer then finds the item(s) they wish to purchase by scrolling through all the items. Upon finding a specific item to purchase, the

item is selected for purchase by specifying the quantity needed.

iii.      If the customer wants to select more items for purchase, the previous step is repeated.

iv.      If the item selected for purchase is a drone, then the customer then    fills a form. to detail the requirements including desired functionality of the drone and the constraints it must operate within.

v.       Once the customer is finished selecting items for purchase, the

customer taps on the “Check out” button to go to the shopping cart screen.

vi.      All items selected are shown on the shopping cart screen, along with the total price payable.

vii.     The customer is advised to check the items in the shopping cart before payment is made.

viii.    The customer may tap the “Pay now” button to proceed, or the

“Cancel” button to stop the transaction, which also ends the shopping process.

ix.      By proceeding with the order, the customer is taken to a new page on the mobile app where credit card details can be entered.

x.       If the credit card is declined, then an error message is displayed with a message to re-enter the details.

xi.      If the credit card charge is successful, then the amount paid is credited to the customer’s account, and a payment success message (receipt)    is displayed on the customer’s phone.

xii.     After processing payment for the current order, the ‘DRNZ’ mobile app will display recommendations of further items the customer can purchase, based on known customer-preferences. Such recommendations will be displayed on the screen with an “Add to shopping cart” button for the customer to tap if they are interested.

xiii.    If the customer chooses to buy something else, then the shopping process restarts, and payment will be requested for newly bought  items. Otherwise, the process ends.

Process Map Template

Question 21 Continued

a.  Model the shopping process at ‘DRNZ’ as outlined above by filling in the blanks (a to j) in the process map template. You may use the following  labels:

Item Found?	Tap Cancel	Find Item	Tap Pay Now	Recommendations Displayed
Tap on Check Out	Card Declined?	Buy More?	Select more items?	Fill in a form

(5 marks)

b. The above process can be improved by streamlining. Suggest one specific way to do it (by identifying a task to eliminate, and describing how it can  be eliminated) and describe an associated value added for the customer by such improvement.  (3 marks)

c.  Suggest one potential risk that is specific to the case, once the streamlining improvement in part b is carried out.  (2 marks)

Question 22

As discussed in class, GIGO stands for “Garbage In, Garbage Out” .

GIGO can potentially impact the integrity of YBC and DRNZ’s operations. Two such operations are listed below:

1. YBC’s Ants responding to orders in a just-in-time manner. That is, Ants will not be waiting at the Ant Stops for requests.

2.  DRNZ handling orders for drone repairs.

For each operation:

a.  Suggest one specific example of Garbage In, in terms of data/information  input, and one specific corresponding example of Garbage Out, in terms of production or information output.  (6 marks)

b.  Suggest a specific valid precaution that YBC and DRNZ can take to prevent such GIGO.  (4 marks)

Question 23

DRNZ aspires to generate high quality information in the reports they send to  their clients after servicing their drones. Such reports may include information such as:

● The client’s name and address

● The jobs carried out on the drone

● The parts required/replaced, and the quantities used

● The number of hours taken and charged

● The costs involved

● The total amount chargeable

● The ID of the technician(s) handling the job(s)

The quality of the above information can be measured by the following aspects:

●    Accuracy

●     Completeness

●     Consistency

●    Timeliness

●     Uniqueness

a.  Choose three relevant aspects of information quality out of the five listed above, for DRNZ’s service reports. Provide and describe examples (you may make them up according to the context of the case) of quality information from such reports that correspond to each of the three chosen aspects. Marks will be awarded for the relevance of the chosen aspects, and the appropriateness of the examples for each aspect.

For example (you may still choose “Accuracy”, but do not use this example as your answer):

Aspect : Accuracy

Example of quality information : The name of the client is correctly spelt on the report.  (6 marks)

b.  Drones sent in by clients for servicing may contain sensitive and important information.

●    Choose two out of the three goals of the "CIA triad of information security":

●     Confidentiality

● Integrity

●    Availability

●     Provide a specific example of data/information stored in the drones, that may be subject to each of the two chosen security goals. The    examples should be made up according to the context of the case.

●    Suggest one way to properly manage such sensitive information

stored in the drones, for each of the two chosen security goals, while the drones are being serviced.  (4 marks)
