CS507 Assignment # 1 Solution

Question 1: What are the organization, management and technology dimensions of information systems? [3 marks]


Answer:

An information system represents a combination of management, organization, and technology elements. The management dimension of information system involves leadership, strategy, and management behavior. The technology dimension consists of computer hardware, software, data management technology, and networking/telecommunication technology (including the internet). The Organization dimension of information system involves the organization’s hierarchy, functional specialties, business processes, culture, political interest groups.

Question 2: Describe some of the major changes that information systems are bringing to organizations. [3 marks]

Answer:

The flattening of organizations is probably one that students will cite, particularly with the concern over downsizing. The parallel increase in information and in the decision power of line workers (empowerment), and their corresponding increase in work satisfaction, is often missed in media reports of downsizing. The flexibility of organizations in operations, for example, custom manufacturing and in linking customers and suppliers (thus reducing order time) are some of the major changes

Question 3: Describe the two factors that explain why organizations adopt information systems. [4 marks]

Answer:

• Customers now prefer to execute transaction in an electronic environment through online-trading. Also the establishment of customer services centers has also removed the inconvenience to access vendor’s physical locations.

• Due to absence of physical contact, companies are curious to keep a soft touch in an efficient manner. This requires keeping a customer-wise online track of past correspondence and transactions

QNo#1


Q2. What is the difference between Cold sites, Warm sites and hot sites? Explain it in your own words.
There are three different types of backup sites:
Cold backup sites
Warm backup sites
Hot backup sites

Obviously these terms do not refer to the temperature of the backup site. Instead, they refer to the effort required to begin operations at the backup site in the event of a disaster.

Difference between cold site, warm site & hot site:

A cold backup site is little more than an appropriately configured space in a building. Everything required to restore service to your users must be procured and delivered to the site before the process of recovery can begin. As you can imagine, the delay going from a cold backup site to full operation can be substantial.
Cold backup sites are the least expensive sites.

A warm backup site is already stocked with hardware representing a reasonable facsimile of that found in your data center. To restore service, the last backups from your off-site storage facility must be delivered, and bare metal restoration completed, before the real work of recovery can begin.

Hot backup sites have a virtual mirror image of your current data center, with all systems configured and waiting only for the last backups of your user data from your off-site storage facility. As you can imagine, a hot backup site can often be brought up to full production in no more than a few hours.

A hot backup site is the most expensive approach to disaster recovery.
Backup sites can come from three different sources:
Companies specializing in providing disaster recovery services
Other locations owned and operated by your organization
A mutual agreement with another organization to share data center facilities in the event of a disaster

Each approach has its good and bad points. For example, contracting with a disaster recovery firm often gives you access to professionals skilled in guiding organizations through the process of creating, testing, and implementing a disaster recovery plan. As you might imagine, these services do not come without cost.
Using space in another facility owned and operated by your organization can be essentially a zero-cost option, but stocking the backup site and maintaining its readiness is still an expensive proposition.

Crafting an agreement to share data centers with another organization can be extremely inexpensive, but long-term operations under such conditions are usually not possible, as the host's data center must still maintain their normal production, making the situation strained at best.
In the end, the selection of a backup site is a compromise between cost and your organization's need for the continuation of production.

CS507 - Solution of Assignment # 2
Impact on Economy
This technology contributes to several national economic prosperity goals. Its major contribution is to job creation and economic growth because it is an essential part of the new manufacturing infrastructure centered on computer- controlled manufacturing. For example, by contributing to producibility and lower costs of "clean cars," CIM support software plays an important role in making clean cars more economically viable and giving U.S. industry advantage in the new generation of vehicles for world markets. It provides one of the tools which can be used to excel at the products and processes identified by the NEMI as essential for future competitiveness of U.S. electronics industry in world markets. It provides the capabilities to work with new materials tailored specifically to the needs of automotive, electronics, construction and aircraft industries, and is essential to the design and economic production of sophisticated new automobiles and aircraft. Finally, CIM support software contributes to the harnessing of information technology because many of the physical components of the information infrastructure, e.g., integrated circuits, can be manufactured more productively with reliance on CIM.
..................
CIM BENEFITS
According to the U.S. National Research Council, CIM improves production productivity by 40 to 70 percent, as well as enhances engineering productivity and quality. CIM can also decrease design costs by 15 to 30 percent, reduce overall lead time by 20 to 60 percent, and cut work-in-process inventory by 30 to 60 percent. Managers who use CIM believe that there is a direct relationship between the efficiency of information management and the efficiency and the overall effectiveness of the manufacturing enterprise. Thacker's view is that many CIM programs focus attention on the efficiency of information management and the problems that come with it instead of developing new and more sophisticated manufacturing machines, material transformation processes, manufacturing management processes, and production facilities. Computer-integrated manufacturing can be applied to nonmanufacturing organizations by changing the manufacturing focus toward a service orientation. CIM and Job Definition Format (JDF) are becoming increasingly beneficial to printing companies to streamline their production process
