Question 1 (18 marks 54 minutes)
Required:
A) Define enterprise resource planning system and provide a rationale why using an ERPsystem might have been more appropriate for Roma than a combination of functional
area information systems. (2 marks)
Definition of ERP system
(text, pg250)
Systems that integrate the planning, management and use of all of an organizations resources,employing a common software platform and database
Rationale why using an ERP system might have been more appropriate for Roma than a
combination of functional area information systems
- provide information about the separate business lines and integrate it into a common platform
- provide access to a common information/data resource to all departments
- promote a coherent organizational structure
- provide more precise and timely information throughout the organization
- potential for better decision making
- Unified technology platform
- promote an efficient, customer driven operation
- Reduce data isolation / data silos / data dependence when info in integrated into enterprise
wide systems
B) Describe two Market pressures relevant to Roma and indicate the role that informationtechnology could play in responding to this pressure. (4 marks)
Name and description of Market pressure Role that information technology could play in
responding to the market pressure(text pg16/17)
Global economy and strongcompetition
-facilitated by www and regional trade
agreements (nafta,eu,etc)
-higher labour cost in developed
countries due to increase employee
benefits results in labour-intensive
industries moving to low labour-cost
areas.
- IT makes it easier for business to trackchanges in and utilize advantageous
portions of trade agreements
- IT makes it easier to move operationsthrough assistance with sourcing a new

The need for real-time operations-Organizations are required to have
adequate information systems and
technology to provide real-time
processing
-Organizations lose competitive edge if
not using these systems
- IT is at the heart of real-time 24/7operations.
- IT provides the platform that enablesreal-time systems.
The changing nature of the workforce-Workforce is more diverse (increasing
number of women, minorities,
handicapped, etc)
-These different people bring diverse
backgrounds and skills to theorganization which require new
management techniques.
-Telecommuting impacts are becoming
pervasive, requiring more management
awareness.
- IT provides a common communicationsplatform for groups.
- Telecommuting requires IT support.- Workplace diversity and ethics are
managed more effectively with the aidof IT support.
Powerful customers- As customers become more
knowledgeable about product/service
quality their expectations increase
- Organizations have recognized the
importance of customers and are
working harder to retain them
- IT supports CRM efforts in theorganization
- IT enables a more consistent customerexperience throughout the
organization.
C) Name two core modules of an ERP system and describe how each would help Romaresolve their current business system problem. (2 marks).
Name and description of ERP core module (text pg. 252)
Financial Management - Support accounting, financial reporting, performance management,
and corporate governance. They manage accounting data and financial processes such asgeneral ledger, ap/ar, etc. Roma would reduce the reliance on manual processes as well as
provide more up-to-date financial info at lower cost to the firm.
Operations Management Manage the various aspects of production, planning, and execution
such as demand forecasting, procurement, and materials planning. Roma would use operations
managements software to aid in the planning logistics of raw materials or productions planning.
Human Resource Management Support personnel administration (i.e. workforce planning,
recruitment, performance, etc) time accounting, payroll, benefits, and regulatory requirements.
As a small group, Roma could take advantage of more automated planning and benefits
managements for its employees

F) The implementation of the new ERP system would also require the acquisition of newserver computers with a new operating system. Roma is considering the use of opensource operating system software. Provide two advantages and two disadvantages of
using an open source operating system. (4 marks)
Advantages of open source operating system
1. Source code for opensource software is available at no cost to developers or users2. Opensource software products have worldwide communities of developers who write and
maintain the code.
3. Opensource development produces highquality, reliable, flexible (code can be changed tomeet the needs of the user), lowcost software.
4. Opensource software considered more reliable than commercial software.5. Because the code is available to many developers, more bugs are discovered early and
quickly and are fixed immediately6. Support for opensource software readily available from firms that provide products derivedfrom the software.
Disadvantages of open source operating system
1. Roma would have to have buy maintenancesupport contracts from a third party, if it does not
have inhouse technical experts (also true for commercial software).
2. Ease of use, amount of time and expense needed to train users, and the compatibility with
existing systems or with the systems of business partners is questioned.

B) Describe two types of electronic cash payment methods HMV could provide for theironline customers. For each one state the main benefit over the use of electronic credit and
debit cards. (4 marks).
Describe two electronic cash payment methods Main benefits of this type of electronic
payment system for HMV over the use of
electronic credit and debit cards.1.Person-to-Person Payments
PayPalToday, 2Checkout and Authorize.Net compete with
PayPal so will be acceptable as well as an answer.
Person-to-Person Payments a is form of e-cash that
enables two individuals or an individual and abusiness to transfer funds without using a credit
card
Chp. 6.4.
*Attractive security feature
You have to put only enough money in the account to
cover any upcoming transactions. Therefore, if
anyone should gain access to your account, they will
not have access to all of your money.
*One account, one username, one password easy to
use.
2.Digital Wallets
Digital Wallets is a software mechanism that
provides security measures, combined withconvenience, to EC purchasing. The wallet stores
the financial information of the buyer, such as credit
card number, shipping information, and so on.
Chp. 6.4
If the wallet is stored at the vendor's website, then
it does not have to travel on the Internet for eachpurchase, making the information more secure.
The wallet stores the financial information of the
buyer, such as credit card number, shipping
information, and so on. Thus, the buyer does not
need to re-enter sensitive information for eachpurchase
Also:
Stored-Value Money Cards - Although they resemble credit cards, stored-value money cards actually are aform of e-cash. They allow you to store a fixed amount of prepaid money and then spend it as necessary. Each time youuse the card, the amount is reduced by the amount you spent.
Smart Cards-They contain a chip that can store a considerable amount of information (more than 100 times that of astored-value money card). Smart cards are frequentlymulti-purpose; that is, you can use them as a credit card, a debit
card, or a stored-value money card. In addition, when you use a smart card in department store chains as a loyalty card, it
may contain your purchasing information. Advanced smart cards can help customers transfer funds, pay bills, andpurchase items from vending machines.

C) Identify two examples of security threats that could occur to HMVs online store. Foreach one provide an example of an action that the HMV could take in order to preventthis threat or minimize its consequences. (4 marks)
Two examples of security threats that couldoccur to HMVs online store
Example of an action that the HMV could takein order to prevent this threat or minimize its
consequences
1.Denial-of-Service AttackAn attack in which the attacker sends so many
information requests to a target such as the company
website, the target cannot handle them successfully and
typically crashes.
Communications (network) controls secure the
movement of data across networks. Communications
controls consist offirewalls, anti-malware systems,
whitelisting and blacklisting, intrusion detection
systems, encryption, virtual private networking (VPN),
secure socket layer (SSL), vulnerability management
systems, and employee monitoring systems.
2. Theft of Information: Cyber-attacks
Hackers will try to steal customers information &
credit cards information that stored on the company
online database.
Access controls restrict unauthorized individuals from using
information resources. Access controls can be physical
controls or logical controls. Such as Authentication,
authorization including strong password and special
questions for the users when they logged-in.
Also:
Software attacks have evolved from the outbreak era,
when malicious software tried to infect as many
computers worldwide as possible, to the profit-driven,
web-based attacks of today. Cyber-criminals are
heavily involved with malware attacks to make
money, and they use sophisticated, blended
attacks typically via the Web.
Viruses, Worms, Trojan horse
Anti-malware systems, also called AV or antivirus software,
are software packages that attempt to identify and eliminate
viruses, worms, and other malicious software

D) ALDO is considering the use of the following types of computing. Provide a definitionand explain how ALDO could use the following computing technologies. (4 marks)
Define Cloud computing: (p 368) Specific example of how it could be appliedto ALDO
-Tasks are performed by computers physically
removed from the user and accessed over anetwork, in particular the Internet. The cloud
is composed of the computers, the software on
those computers, and the network connections
among those computers. The computers in the
cloud are typically located in data centres, or
server farms, which can be located anywhere inthe world and accessed from anywhere in the
world.The cloud incorporates the characteristics of
grid computing and utility computing on a
global basis. That is, the cloud supplies as
many computers as are needed for a particular
task (grid computing) and users pay for the
amount of actual processing and storage used
(utility computing).
ALDO could use cloud computing to provide
the infrastructure and applications softwaremanagement and operations for its worldwide
supply chain and inventory management.
It would be readily accessible to all it
operating units worldwide, efficiently and with
unlimited capacity to handle spikes in activityas well as scalability to effectively
accommodate the companys continuinggrowth.
-would facilitate the availability of real-time
exception reporting and business intelligence
information transfer to ALDOs key decision
makers in Montreal and other major centres
-far less expensive and time consuming forimplementation of the new SCM systems than
Define Utility computing: (p 368) Specific example of how it could be applied
to ALDOA service provider makes computing resources
and infrastructure management available to a
customer as needed, charging the customer for
specific usage rather than a flat rate.
Utility computing enables companies to
efficiently meet fluctuating demands for
computing power by lowering the cost ofowning hardware infrastructure.
Utility computing also provides fault tolerance,redundancy, and scalability. That is, if one
server fails, another takes it place. Scalability
means that if an application requires additionalservers, they can easily be added as they are
needed.
Similar to Cloud Computing examples,
- to provide infrastructure and applications
software management and operations for
ALDOs supply chain and inventory
management
-Would accommodate spikes in activity aswell as scalability to effectively accommodate
the companys continuing growth.
