The following five questions refer to Crowdmark. Crowdmark is a marking management system used in INFOSYS 110 to scan, mark, moderate, and communicate your test and exam scripts. The most important information that Crowdmark manages are the marks, which is handled by its Database Management System (DBMS).
12. Crowdmark is used in many courses across the University. It has successfully managed test and exam marks for a range of courses from small (30 students) to huge (over 2000 students). Course staff hence trust the system to manage marks securely: only staff with the correct permissions can see students’ scripts and marks; students can only see their own scripts and marks. This is an example of Crowdmark’s DBMS providing:
a. Tables and fields
b. An organised collection of logically related data
c. Scalability and information security
d. Hardware and networks
e. Social and cloud computing
13. When a question is marked, Crowdmark automatically adds up the marks for each
question on every student’s script and perfectly calculates the total mark. Crowdmark can also alert markers to scripts which have missing pages or unmarked questions.
Crowdmark offers these functionalities to support high-quality information by ensuring marks are:
a. Accurate and timely
b. Complete and timely
c. Consistent and timely
d. Accurate and consistent
e. Complete and consistent
14. Students can view their marked scripts in Crowdmark using a web browser on a PC.

a. Hardware; networks; software
b. Software; networks; hardware
c. All of the options are valid as software, hardware, and network components are interchangeable
d. Software; hardware; networks

a. Access; confidentiality
b. Physical; integrity
c. Access; availability
d. Communication; confidentiality
e. Communication; availability
16. Every time a marker or a student uses Crowdmark on a web-enabled device, what type of connection is established in order to exchange digital information between the device and Crowdmark’s web servers?
a. Protocol
b. Ethical
c. Physical

SECTION B:
SHORT ANSWER QUESTIONS
Refer to the case attached to the end of this booklet to answer ALL the questions in this section.
The roadmap is provided as a reference and you should use it as a guide when answering the questions:
26. Using evidence from the case, identify:
a) Two of W2's suppliers, two of W2’s customers, and one of W2’s partners. (5 marks)
b) Which value discipline W2 primarily focusses on, and a corresponding Value Chain Activity W2 should invest in to excel in the discipline. Justify your answers. (3 marks)
c) How W2 adds value for their customers. (2 marks)
(10 marks)
27. Consider the model of the W2’s “Hydrometer smart meter installation process” provided below to answer this question.
a) For any two steps of the process model, suggest a specific information system that could be used to support the step. Draw your answers on the model provided in your answer booklet. (2 marks)
b) For any two steps of the process model, suggest a department within W2 that would perform the step. Draw your answers on the model provided in your answer booklet. (2 marks)
Note: the steps you choose for questions a) and b) may be the same steps; you may choose any two steps for either question.
c) Our definition of a business process stated it “achieves a specific outcome” . What is achieved in this process? (2 marks)
d) Suggest one way Business Analytics could be used to improve this process for either W2 or its customers. (4 marks)
(10 marks)
28. Information Systems consist of interwoven components that deliver value. Using
evidence from the case, identify examples of the components of Hydrometer.
Hydrometer is W2's water usage monitoring and management system. For each example, briefly explain why it is necessary for the overall Information System to function and deliver value.
(10 marks)
29. Before W2 can run their “WaterWise world-wide” (W4) campaign, some preparation is required. The necessary activities will be performed in a project named “Prep for W4” .
Some details about Prep for W4:
• It is scheduled to start at the beginning of January 2019.
• All activities must be completed before the end of July 2019, around two weeks before International Water Week.
• A crucial activity is to finalise agreements with the charities involved.
• Another crucial activity is to correctly calculate the benchmark water consumption quantity.
• The lead project manager is Nat Dean.
• Including Nat, there are six members of W2 staff working on this project. Nat is assigned full time (approximately 40 hours per week), all other staff are
allocated half-time (approximately 20 hours per week per person).
a) What is the time constraint of the Prep for W4 project? (2 marks)
b) What is the cost constraint of the Prep for W4 project? (2 marks)
c) Assume the project experiences delays, and with the deadline imminent, both the
crucial activities have yet to be completed. Suggest one way Nat can “balance” the constraints of this project. Also explain the impact of your suggestion on the “quality” of the Prep for W4 project. (4 marks)
(8 marks)
30. In this course we have frequently discussed how information systems (IS), information technologies (IT), and operations management (OM) techniques, when used well, generate business value.
For EACH of the categories of value below:
• Describe how W2's use of IS or IT or OM generate value for itself.
• For your answer above (the value generated for W2), provide a specific key performance indicator (KPI) to measure it.
• For your answer above (the KPI), state whether W2 would want its figure to
increase, decrease, stay the same, or to be ignored completely. Briefly justify your choice.
a) Reduce costs
b) Increase customer satisfaction
c) Create competitive advantages
