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.  Model RevLine’s customer order process. Link two different information systems (from the case only) to the appropriate steps.  (10 marks)

27.  Write the two specific systems you identified in Question 26 in the appropriate place on the answer booklet. For EACH system:

•   State what broad category of information systems it falls under

•   Identify TWO pieces of hardware that are part of the system

•   Identify TWO functionalities of the system                                                   (10 marks)

28.  Rochelle  Babushka  has  been  tasked  with  manufacturing  the  shipping  containers  for RevLine’s new project. However, she has just been informed that RevLine’s R&D team are investigating the development of a new line of cruiser motorcycles which will require extremely different containers for shipment.

a.   What would be the  effect on the project management triangle if the project was to include  both  the  current  motorcycle  models  and  the  new  cruiser  models  under development?   (2 marks)

b.   Would the scale of the effect have been different if Rochelle had been told of R&D’s decision to develop a new motorcycle model earlier?   (4 marks)

29.  Consider the Customer Order Process section in the case. Identify TWO examples of information generated. For each example:

•   Identify whether each example is transactional or analytical information

•    Suggest what insight RevLine could gain from the information                           (12 marks)

30.  In this course, we have frequently discussed how information systems and technologies   (IS/IT) and operations management (OM) techniques, when used well, generate business value.

For EACH of the categories of value below, provide an example of how RevLine’s use of IS/IT and/or OM generates value for itself, or its customers. Also provide a specific  key performance indicator (KPI) to measure the value, and an example of a benchmark which RevLine could compare against to determine if the KPI is improving or not.

•   Reduce cycle time

•   Reduce costs

•   Increase customer satisfaction

•   Create revenue streams                      (12 marks)

RevLine Motor Company (RevLine) is aiming to disrupt the motorcycle industry

When Jay  Stephanopoulos was  looking  for  his next motorcycle  in 2017,  it  dawned  on him that motorcycles were sold only in physical  stores, either by manufacturers themselves or third party motorcycle dealers. Manufacturers shipped to dealerships around the world, who sold to end users. Companies maintained expensive inventories at each stage of this supply chain, and end users had to “settle” for standardised options, with expensive modifications being the only way to customise a motorcycle through official channels.

Stephanopoulos thought that if he could eliminate the retail channel by selling motorcycles directly to consumers, he could dramatically reduce prices, and so he started RevLine Motor Company. Operating without retail stores reduces costs and brings RevLine closer to the customers, enabling it to listen to them better than its competitiors. It also eliminates sales channel inventories, which allows RevLine to rapidly bring new motorcycles with new technologies to its customers. In fact, RevLine builds every motorcycle to customer order. Every motorcycle in RevLine’s finished goods inventory has already been sold. Additionally, RevLine works closely with its suppliers and now has one of the most efficient supply chains in the industry.

As it doesn’t have any physical stores, RevLine partners with a number of motorcycle repair garages to ensure that its customers have convenient options for repair and maintenance work on their motorcycles. These “Partner Garages” are its customers’ only opportunity for face to face contact and so RevLine has a high standard for selecting its Partner Garages in every location.

Shipping Project

It can be very complicated to ship new motorcycles to its customers directly. Therefore, RevLine currently ships every motorcycle to a Partner Garage closest to its customer. For a small fee (paid for by RevLine), the Partner Garage will unbox the motorcycle and ensure that it is ready for the customer to pick up and ride away. However, RevLine is currently exploring ways it can ship to the customer directly whilst still ensuring that it is easy for its customers to start riding as quickly as possible. The avenues still to be researched by the project team include:

•     Using crates made from easily recyclable materials (e.g. strengthened cardboard),

•     Providing  clear  instructions  for  the  customer  to  easily  remove  the  motorcycle  from  the packaging, and prepare the motorcycle to be ridden,

•     Working to ascertain whether specialist motorcycle delivery companies are needed or whether regular freight / logistics companies can manage delivery.

RevLine’s Customer Order Process

A customer submits an order through the website, supplying their name, e-mail address, physical address and credit information. At the online store, they may choose the model to purchase, as well as any factory customisations they would like  (e.g.  seat height). The  order is received by  an order processing system, which reads the data and appends an ID number to the order. The order is forwarded to a customer service representative, who checks the customer’s credit information. If the credit check fails, the customer service representative is assigned the task of notifying the customer to obtain correct credit information, and the process becomes manual from this point on. If the credit check passes, the system checks a database for the current manufacturing capacity of the factory responsible for the customer’s order. If the manufacturing plant has reached capacity then the order is put on hold until the manufacturing plant signals that it has capacity again. The customer is notified of this via e-mail. If the plant can make the motorcycle within the allowable timeframe. the order goes ahead. Once the product is manufactured, the order is forwarded to a shipping agent who ascertains the nearest Partner Garage and arranges shipment. Finally, the system calculates the total price of the order and confirms that the order has been shipped. Once this is done, the customer and Partner Garage are notified via e-mail.
