ASSIGNMENT NUMBER: 2
ASSIGNMENT TITLE: Managing Information Technologies and Resources
QUESTIONS/ANSWERS
TASK SET 1: Chapter 5: MUST READ: Distributed Systems: The
Overall Architecture
Review Questions
3) What does “open source” mean?
It means that source code of a software can downloaded on the
internet for free and thus can be modified.
4) List and briefly explain the questions that can be asked in whether
to distribute computing responsibilities.
a) Are the operations interdependent? Interdependency means one
operation needs to know what another is doing. Therefore, their
planning, software development, machine resources, and operations
must be centrally coordinated to synchronize their operation.
b) Are the businesses really homogeneous? When operations do not
need to know what each other is doing, then many systems
functions can be decentralized, unless the operations truly have
a lot in common.
c) Does the corporate culture support decentralization? Even if the
business units do quite different things and do need to know what
each other is doing, corporate culture might dictate that some
functions be decentralized.
9) What are server-based computing and peer-t-peer computing?
Server-based computing is the concept of housing programs on the
Net. It not only applies to small Java applets but also to, for
example, providing in-house applications to mobile employees.
Peer-to-peer computing is the concept of distributing a task over
a wide number of computers (peers) connected to the Internet.
Discussion Questions
2) Is Internet-centric computing taking us back to the architecture of
mainframes and dumb terminals? Are we coming full circle? Why or why
not?
Internet-centric computing is an underlying principle of a
distributed environment where applications and data are downloaded
from network servers on as-needed basis. It is a contrast with
current use of powerful personal computers that rely primarily on
local resources. It is not architectural model of mainframes and dub
computers.
Exercices
4) Find a description of an Internet-based application. Why was this
approach taken? What benefits are expected?
Healtheheart is an internet-based Cardiovascular Disease
Management application that integrates accepted medical guidelines
into patient management protocols for use by physicians or
physician extenders.
The approach is taken to create a patient tracking system through
a real time data repository that includes historical analysis
tools, documents, and demonstrates outcomes-based medical care.
Benefits expected:
1) Internet-based physician or patient management tool
2) Risk management and compliance monitoring
3) Secure internet-based technology
4) Unlimited encrypted email
5) Better utilization of drug protocols
6) Real-time historical
TASK SET 2.0: ALTERNATE: Chapter 6: Managing Telecommunications
Review Questions
2) What is “the last mile,” and why is it a problem?
It is the connection between a subscriber and the telephone
company’s central office where the network switching resides. It is
a problem because it a bridge where fiber optic cables at the speed
of 1 terabit connect and communicate to twisted pair phone lines
operating at the speed of 56 kbps.
5) Describe the functions of hubs, switches, and routers.
Hubs are repeaters; they forward packets of data from one machine
to all machine within a network.
Switches are smarter than hubs; they only forward packets of data
to the of the intended computer.
Routers are smarter still; they use a routing table to pass along
a packet to the next appropriate router on a network.
6) How does voice-over IP work?
It works with a special IP phone, with an Ethernet jack in the back
instead of the standard telephone jack, is attached to a company
LAN. Rather than the analog signals sent by traditional phones, the
IP phone generates a digital signal. That signal is routed over the
LAN just like any other data, in packets, either to (1) another IP
phone on the LAN, (2) through the company’s WAN to a distant IP
phone on another of the company’s LANs, or (3) through an IP voice
gateway to the public switched telephone network to a standard
telephone.
8) Give some examples of uses of wireless LANs.
a) In older buildings where the wiring ducts are full.
b) Backup for important applications that run over wired networks.
c) A fixed setting where a wireless LAN can be configured more
quickly, adding, moving, and changing participants.
12) Why is “always on” important?
Because it allows instant communication
14) What are the three roles of the IS department with respect to
telecom?
a) Create the telecom architecture for the enterprise
b) Run it
c) Stay close to the forefront of the field.
Discussion Questions
1) The chapter implies that a company should stay at the forefront of
telecommunications technology lest it fall seriously behind. On the
other hand, it might be better to let others go first, and then
learn from their mistakes. When is each approach most appropriate?
Why?
The first approach deals with technologies that have been on a
market for some time and that are being developed by new vendors.
Because companies have some experience handling those technologies
and only need to upgrade their systems to use new features.
The second approach deals with new technologies that have not been
proven to be safe or reliable. Because companies can learn from
mistakes made by other companies while implementing a new system.
2) None of us needs a phone at home and a phone at the office. All we
need is one phone that we always carry around. Such a practice would
relieve the pressures on the telephone system for so many additional
phone numbers and area codes. Better yet, each phone should have an
IP address. Discuss the pros and cons of these ideas.
I always dream of such a practice. It would be great for customers
service providers. But. The problem comes with getting telephone
companies to agree on a numbering system that would fit that
practice.
TASK SET 4.0: MUST READ: Chapter 8: Managing Operations
Review Questions
1) What is the main shift in operations viewpoint?
The main shift in operations viewpoint is managing outward, that
is, managing the company’s relationships with external IT service
providers who have taken over the day-to-day operational work.
4) What have Y2K and the Internet done for computer operations?
Y2K and the Internet gave computer operations the attention it
needed, but had not gotten.
6) How thoroughly are CIOs expected to investigate outsourcing?
CIOs are expected to investigate outsourcing sufficiently to
satisfy executive management that there is operations are as
efficient and effective in-house as they would be if they were
outsourced
8) What are the five customer-vendor relationships?
Professional services, product, transactions, systems integration,
and outsourcing.
9) What are IT outsourcing, transitional outsourcing, best-of-breed
outsourcing, shared services, business process outsourcing, e-
business outsourcing, and application service providers?
IT Outsourcing: is a deal which consists of outsourcing all a
company’s data center operations for up to ten years.
Transitional Outsourcing: is used by CIOs, with their hands full
supporting legacy systems, to transition to client-server computing.
Best-of-breed Outsourcing: is a selective outsourcing, where one
company handles desktop operations, another data center operations,
and a third network management.
Shared Services: are “insourced” organizational units for functions
Such as IT, legal, real state, travel, mail room.
Business Process Outsourcing: is outsourcing all or most of a
reengineered process that has a large IT component.
E-business Outsourcing: is used by dot-coms and Internet-based
companies to handle all or almost of the IT function.
Application Service Providers: are companies that rent software to
others over the Internet.
16) What internal disaster recovery alternatives are used by companies?
Multiple data centers, distributed processing, backup telecom
facilities, and local area networks.
17) What external disaster recovery services are available to
companies?
Integrated disaster recovery services, specialized disaster
recovery services, online and off-line data storage.
Discussion Questions
1) Outsourcing offloads a burdensome technical responsibility and
allows management to focus on its core business. Outsourcing strips
a company of an important core competency--IT know-how. What
statement do you agree with? Why?
I agree with the first one. Because outsourcing allows companies
to go outside their own organization to obtain specialized services
of various kinds. This process links growing businesses to a range
of state-of-the-art services and resources not available before.
3) The
Internet provides all the redundant routing and alternate sites.
an enterprise
needs. It need not contract with a backup and recovery
firm as Household International did. Present arguments against this
belief.
Despite all the Internet has to offer, companies must not rely on
it for dramatic events such as ‘system crash’. They need an outside
contractor for integrated disaster recovery services, specialized
disaster recovery services, online and off-line data storage.
INTERNET TASK 1: Term: Middleware
URL: http://www.webopedia.com/TERM/M/middleware.html
Middleware: software that serves as a bridge to pass data between two
applications. For example, a middleware software can link a database
system to a Web server.
INTERNET TASK 2:
Then write a paragraph or two about some of the key things that you
learned that were not in your text.
The OSF Distributed Computing Environment (DCE) is an industry-standard, vendor-neutral set of distributed computing technologies. DCE is deployed in critical business environments by a large number of enterprises worldwide. It is a mature product with three major releases, and is the only middleware system with a comprehensive security model. DCE provides a complete Distributed Computing Environment infrastructure. It provides security services to protect and control access to data, name services that make it easy to find distributed resources, and a highly scalable model for organizing widely scattered users, services, and data. DCE runs on all major computing platforms and is designed to support distributed applications in heterogeneous hardware and software environments. DCE is a key technology in three of today's most important areas of computing: security, the World Wide Web, and distributed objects.
INTERNET TASK 3:
1. How will 9/11 change the way we perceive disaster recovery planning?
9/11 will force companies to always think about the “unthinkable”
in a way to build backup systems that will take over in case of
disastrous events. Also, companies will maintain some type of
offsite data storage.
2. What has your organization done to change its disaster recovery
plan?
The company I am working for has moved some backup servers to
offsite locations.
3. What does your organization plan to do in the future because of
9/11?
They are planning to hire an external contractor to store and
maintain their important data. Also, they want to open an
out-of-state office with the capability to run daily operations if required.
4. Develop a table of contents for a disaster recovery plan that takes
into account the lessons learned about disasters post 9/11?
a) Test the system in a monthly basis.
b) Update the system according to the growth of the organization.
c) Improve the system according to the advances in technology.
d) d) All important data are backed up and stored offsite.
e) Create a secondary location that will be fully functional and
capable to take over daily operations.

MMIS 620 Management Information Systems
Assignment – 2. Managing Information Technologies and Resources
Managing information resources at the corporate or centralized level

Noorlander, W. (2001). Information management who’s controlling who?
(managing and purchasing information).Journal of Management
Information Systems, 15, 99–112.
Subject Headings: market data, information suppliers, cost control, management of information, chief information manager.
STATEMENT OF THE PROBLEM.
For the past 10 years, there have been drastic transformations in managing a company’s information systems. In the beginning, much of the focus was placed on the network. However, this information proved inadequate, yielding way to more advanced information management. Thus managing information resources has evolved into a complex system of buying, managing, and improving information. Yet, many big particularly conglomerates and global businesses, have no idea of the size of their problems because they do not know how much information they use. They do not know where it is used, the suppliers, or its value. They almost never know how much their information supply chain costs them.
STRATEGIES OR TECHNIQUES USED TO SOLVE THE PROBLEM.
1. Companies must determine their business objectives and how much information they need. Also, they have to decide on the information sources that best allow them to meet those objectives.
2. Companies must understand exactly what information providers are offering them and capable of answering the following questions:
a) What is the current level of data offered by each particular
vendor?
b) Do vendors originate data, redistribute data, or both?
c) What is the current access or means of delivering the data?
d) What is the current ownership and family relationships among
information suppliers.
e) Are we current on industry alliances within the information
industry?
3. Companies must control the usage and expense level of information
and know how much of it they use, where it is used, and why they
are using it.
4. Hire an expert as Chief Information Manager with the responsibility of managing information, both usage and expenditure. This CIM will report to the company’s CIO.
CONCLUSIONS AND RECOMMENDATIONS.
There are more sources of information every day; not necessarily more types of information. But different cuts of the same data or new ways to have access to that data. The firms that excel will be those that use information as a resource and to maximize value, both for current and new types of uses. To maximize the value, companies have to be in charge, and in control of the process. They need to focus on their objectives, understand the information industry and current level of offerings, and bring in the right level of expertise to manage the process.
SUGGESTIONS FOR FUTURE RESEARCH OR DEVELOPMENT ACTIVITIES.
Any future research will focus more on the role of information and market data into the new knowledge e-economy.

CASE ANALYSIS (Text-Based):
THE MAIN PROBLEM THAT WAS OR IS TO BE SOLVED:
What is the main problem in the case that reflects the and the pain that led the organization to design the system or search for the solution?
NW Airlines need to accurately and quickly calculate revenue from
passengers in order to compete as a major world-class carrier.
What are some side issues in the case?
1. NW have doubled their business after merging with Republic
Airlines.
2. NW needs to audit all their redeemed tickets.
3. Sampling of passenger ticket to estimate revenue did not yield
accurate revenue data.
RECOMMENDATIONS:
What are your comments or thoughts on the way the problem
was approached in this case?
I think the system was implemented in ways to effectively help
Northwest better calculate revenue because it uses integration and
other technologies such as relational databases, imaging, and expert
Systems.
What additional resources need to be expended to do an even better
job of resolving the problem?
a) Northwest should create a program that will compute a daily report
on all refunds made to customers that have voided their tickets.
b) Northwest must upgrade their mainframes so as to close monthly
books on the third on the month. Thus, earned revenue could be
100% faster.
What are some of the “way out” things that the organization
could have done. Dream a bit.
Northwest should create a real-time expert system that would process
the passenger revenue accounting like an inventory data system
allowing the company to close the monthly book the 1st day of the
month.
UPDATE
SHORT-TERM VIEW: State some recent changes that have occurred in the specific industry of the case organization that may have an impact on the organization in this case in the Short-term (one year to 18 months out).
On May 2001, the International Air Transport Association (IATA) launched a new e-ticketing system GlobalET. This system offers airline worldwide a globally available e-ticketing service, which has the capability of integrated interline ticketing. Using this system, Northwest will be able to better and faster process ticket sales made from online reservation systems. Overall, the new system will help Northwest to be more efficient in calculating revenue from passengers.
LONG-TERM VIEW: What changes do you predict for this system? The industry is constantly changing and there will be areas
That will be upgraded or made absolute by new technology. Briefly describe what you think will happen to this system in the next 2-5 years.
With the increasingly use of Internet and the advancement in technology, I see the system improved to become very effective and be able to produce the revenue from passengers in a daily basis with 99.9%
Accuracy.
Find some recent advertising for the case organization and indicate what are they trying to portray?
In its own Web site, http://www.nwa.com, in a promotional article published on January 23, 2002, Northwest reported that it has checked in over 1 million customers via the Internet. In this article, Northwest tryed to portray itself as an innovative airline company that has transformed every desktop, whether at home or at work, into a place where travelers can conveniently and quickly obtain a boarding for their flight.
OTHER:
What other materials would you have liked to have had about this case organization in order to review it more effectively?
I would like to have a detailed report of the Passenger Revenue Accounting (PRA) to understand if the new system really fits the needs and obligations of such a report.
REVIEW QUESTION:
Develop a one paragraph summary of your activities on this assignment indicating the key points that you have learned.
I started the assignment by reading the chapters needed to answer the required questions. While doing so, I learned about distributed systems
and their overall architecture, the role and importance of the telecom infrastructure within an organization, and the management of computer operations. Next, I completed the Internet tasks where I learned about middleware systems, the distributed computer environment, and discovery recovery planning. By doing the Reading Review, I understood the importance of purchasing and managing information within a company. Finally, I did the Case Analysis of Northwest Airlines and Manitoba, in which I learned about XML integration systems.
EMBEDDED EVALUATION ITEMS:
1. What direct applications were you able to make to your job? If you
do not have a job, indicate what concepts seem most practical to
you.
I was able to understand that information is a crucial and
critical raw material for my company. The range, quality, and depth
of information, coupled with the speed and level of access, are the
key factors in their success level.
2. How could the existing objectives and tasks in this assignment be
modified to make them more useful to you?
The overall tasks of each assignment could be reduced by 25%.
Instead, each student would have to complete a Project Research in
an existing company on a issue related to the assignment.
