Today, she can simply ask a bot: "What shade of foundation did I order last?" The bot can then quickly match her identity, find her order history, understand which product she's referring to, and tell her. What's more, she could even ask the bot to re-order it for her. This demonstrates that the AI technology used is an example of:

SECTION B:

SHORT ANSWER QUESTIONS

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

21. A typical SmartCare Smart Apartment installation process is described below:

The installation process begins when a customer order comes through requesting for a smart apartment installation. The receiver then processes the order by sending through a purchase order for the required parts.

Once the parts have been received, the next available technician will be assigned to the job.

The technician then visits the customer’s home to assess and decide on the

appropriate locations for the sensors installations. This is then followed by the

installation and configuration of these sensors with the associated components. The  technician will then monitor to make sure that all associated parts of the smart home are functioning as is, triggering when needed and are reporting valid measurements.

If there are no problems detected, the technician will proceed to sign-off. If there are problems detected, the technician will investigate the potential causes of the problems and communicate the next course of action to the customer.

If the customer is happy with the technician’s recommendation, the technician will proceed to fix the problem. Otherwise, the technician will reschedule another visit with better recommendations and log the job as incomplete.

As part of fixing the problem, the technician will also identify if additional components  are required. If other components are needed, the technician will proceed to order the parts, followed by rescheduling another home visit with the customer. If no additional  parts are required, the technician will proceed to fix the problem.

After the problem has been resolved, the technician will send a bill to the client’s account and log the job as complete.

a.   Model the Smart Apartment installation process outlined above with a process diagram.  (10 marks)

b.   Link TWO different specific information systems and TWO departments to the appropriate steps outlined in the above process.(4 marks)

22. Consider the eCare Dashboard from the case.

●    Identify ONE example of “Transactional” and “Analytical” information that can be generated from the use of the eCare Dashboard.

●    Identify FOUR examples of data inputs for each type of information generated above.

●   Suggest what insight SmartCare could gain from the information in order to generate value for its retirement village and/or its residents.  (8 marks)

23. IoT ecosystems bring about a number of potential risks. In particular, the issues

surrounding the security of SmartCare residents data, where an overabundance of data that are being collected, shared and stored online.

a.   Looking back to the case, identify one such specific potential risk.

b.   Referring to the four major risk management responses covered in class, outline the actions that SmartCare could take for each of these responses in order to deal with this potential risk.  (8 marks)

24. Consider this scenario: With the immensely positive outcomes seen in the current

operation, SmartCare has decided to further invest in establishing another smart retirement village. Honour Moses has been appointed as the project manager to oversee the project. She has been allocated a budget of $200 million and a timeline of 24 months for the new retirement village. With careful planning, Honour is confident that this project is achievable. However, shortly after the start of the project, Honour was told by her manager that her timeline is being reduced to 18 months.

Discuss the impact of this decision on the project in terms of the project management triangle with justifications for your answer.  (8 marks)

25. For each of the categories of value below, provide an example of how SmartCare’s use of IS/IT generates value for itself or its customers.

●    Reduce Cycle Time

●    Reduce Costs

●    Increase Customer Satisfaction

For each example, provide:

● a specific key performance indicator (KPI) to measure that value; and

● a benchmark, which ‘SmartCare’ could compare the KPI against.  (12 marks)

Exam Case: SmartCare - The Modern Retirement Village

Adapted from: https://mapleknoll.org/technology/

As technology becomes an increasingly essential part of our everyday lives, SmartCare, a luxurious continuing care retirement community, is leveraging it to help keep residents in their communities feeling safe, stimulated and healthy. SmartCare knows that retirement looks different to boomers than previous generations, so they are working to create an innovative continuum of care environment where residents can age more independently.

Each resident in the retirement village is equipped with a wearable device. This device collects critical data from the residents, including glucose levels, body temperature, food  intake, sleep habits, bathroom habits, daily steps, location and heart rate. Such data is     then delivered to a central database.  Caregivers can then track the residents’ health and spot any changes in behaviour, by accessing “eCare”, a single dashboard app. On eCare, all caregivers can conveniently access reports about the whole picture of each resident’s health. These data and reports are also updated and delivered to their appointed physicians in real-time. Data collected and updated in this manner can assist  in generating timely health alerts, which can speed up the detection of health issues and aid the physicians’ and caregivers’ decision-making. This is also shown to reduce the costs of unnecessary or prolonged hospitalisation or long-term care.

Late last year, SmartCare decided to partner with Tower Technologies to incorporate more useful technologies to improve the well-being of their residents. Tower specialises in managing solutions such as data centre infrastructure, cybersecurity, data analytics and IoT (Internet of Things) ecosystems. Together, SmartCare and Tower created a Knowledge and Service (KS) lab, catered to SmartCare residents, where they access online and on-site classes on how they can use technologies, for example, Amazon’s     Alexa virtual assistant device, Uber rides and Whole Foods Market (to order groceries).  They can also learn more about smart home technology and obtain recommendations    from in-house staff to find new ways to integrate devices into their daily lives. Residents can then arrange to have new devices and technological services set up in their homes.

For example, in a “Smart Apartment” at SmartCare, the IoT system is linked with sensors placed throughout the home. If a resident gets out of bed in the middle of the night, lights on the floor will come on, to reduce the risk of falling and highlight potential hazards.

Blinds can be set up to automatically adjust, as can lights and even appliances. Smoke  detectors, motion sensors, doorway sensors and more are all carefully selected with the expert input from the Tower team, and are linked to the IoT system. The metrics generated from these sensors are also delivered to eCare, giving caregivers a better picture of their residents’ well-being.

The ultimate goal of this new technology is to help residents live healthier, happier lives in a setting they feel most comfortable with. SmartCare believes that this could significantly improve the residents’ quality of life while reducing an increasing cost on the health-care system. The KS lab is part of their effort to stay ahead of this problem, with a dedicated space where new concepts and prototypes of sensors and systems can come to life.
