2. What are the business benefits of Maxwealth’s intranet? (10 marks)
3. How does Maxwealth’s extranet help strengthen its ties with its agents? (10 marks)
Maxwealth India Ltd, a Rs. 3000 crore diversified property and casuality insurer, largely bypassed client/server technology on its way to the intranet. It did so partly because of the insurance industry’s conservative stance on technology. However, the intranet’s simple application deployment and its potential as a competitive business tool drew Maxwealth’s attention. The web provided Maxwealth with the opportunity to distinguish itself with better, more informed services in an otherwise mature market. That meant a way to strengthen ties with its independent agent network. “This has always been a relationship business,” says the director of collaboration solutions.
MaxNet, Maxwealth’s first intranet application, was an enterprise wide risk management application that went up last year. It allows over 900 customer service representatives to track the account status and identify risk exposures by consulting a reference database of 40,000 policies and information from content experts on specific types of litigation or claims awards. Users make predefined queries, which offer 10 to 20 variables, against a SQL server database; that in turn accesses a DB2 database on the mainframe.
When this system worked well, Maxwealth developed an extranet application for agents selling worker’s compensation insurance. In insurance, where the name of the game is getting quick quotes, Maxwealth’s extranet guarantees response time of 10 minutes or less, compared to hours or days in the old way. The company is also planning an extranet admission system for worker’s compensation claims to streamline a costly process bogged down by paperwork.
And for its top customers, Maxwealth is considering adding a premium service extranet involving virtual private networks to get around the uncertain performance of public networks.

4. Why is Paradigm splitting its top information systems job into two positions? (10 marks)
5. Should other companies appoint CIO and CTO executive to manage their use of information technology? What are the limitations and benefits of this approach? (10 marks)
Most Chief Information Officers (CIOs) dream of creating innovative business applications so that their company gains a competitive advantage. However, they end up spending most of their time dealing with legacy systems maintenance. At Paradigm Consultants, management decided that one executive simply couldn’t shoulder the burden of IT strategy and infrastructure as the company sought to explore new growth opportunities. Hence, Paradigm Consultants split the top technologist position into the position of CIO and the position of Chief Technology Officer (CTO). Companies such as Merrill Lynch & Co., General Motors, and GE Capital Corporation have had CIOs setting and aligning business goals and strategies. But chief technology officers (CTOs) typically handled day-to-day operations.
Paradigm Consultants, split the duties of the CIOs because the time and resource constraints that weighted on them were just too much. Now Paradigm Consultants is in a position to leverage new business opportunities. It can make effective use of the terabytes of data it has on 25 million households and also try to expand the company’s catalog customers.
Paradigm Consultants is in the early stages of bolstering Paradigm Consultants Online with more products and services for sale. According to analysts, the company is also considered to be a technology leader because of its innovative use of database marketing and data mining capabilities.

Section B : Problems/Caselets (50 Marks)
Caselet 1
Read the caselet carefully and answer the following questions.
1. How is the Deccan News responding to competition from online services? (10 marks)
2. What other strategic IT initiatives would you recommend to this newspaper? (10 marks)
The “Deccan News” is positioning itself for the future. Since the Indian newspapers are expected to lose about 10 percent of their revenue to online services, the newspaper has developed some IT strategies of its own. As part of its information technology (IT) strategy. The Deccan News has expanded its use of several electronic communication systems that provide its customers – advertising agencies, a greater control over the development of their display and classified ads.
As a result, the accuracy of ads in the Deccan News has improved. Fewer ads contain mistakes, and the Deccan News handles fewer rebates for its advertising customers. The newspaper hopes to triple the amount of display ads it receives electronically. The paper now uses the Associated Press’s Adsend system, which allows advertising agencies to send ad copy to the newspaper through dial-up connections. As a result, Deccan News production staffers who used to build the ads, can now spend more time laying out the pages. The project was the result of a company wide initiative to formulate a long-term technology strategy. Along with the consulting group, the top management identified certain strategic IT initiatives. Those initiatives included upgrading the newsroom’s outdated terminals and linking the newspaper’s production, advertising and other departments using groupware and electronic-mail systems.
Caselet 2
Read the caselet carefully and answer the following questions.
3. Why does SRC need a GIS? (10 marks)
4. How is GIS a decision support system? Answer this question using PATHPIC and PUTAWAY as examples. (10 marks)
Southern Roadways Corporation (SRC) successfully implemented a geographic information system (GIS) for home delivery routing. As a result, trucks then were able to make more deliveries in less time with greater efficiency. SRC then decided to implement PATHPIC. PATHPIC selects the most efficient route through the warehouse that allows a driver to pick the maximum number of items to be loaded in outbound trailers within the shortest amount of time. This idea of ‘picking for speed’ led SRC to estimate that adding an extra item per forklift per hour would garner them significant yearly financial savings. Not surprisingly, the results greatly surpassed the original estimate. SRC saved the equivalent of two weeks of operations time annually. Prior to PATHPIC, individual forklift drivers selected their own routes through the warehouse to complete a list of items to be loaded into a trailer. The truck drivers also had store delivery schedules to maintain. PATHPIC was implemented in three of SRC’s six warehouses. SRC will implement a GIS called PUTAWAY to streamline the routing of merchandise coming into the warehouses. PUTAWAY will focus on space planning for merchandise once it is offloaded from the delivery trucks onto the receiving docks. Factors such as where to off-load merchandise on the docks and how many stacks of merchandise to create are key to developing a system that will provide optimal efficiency when the merchandise is moved to its respective location within the warehouse. Thus, SRC has capitalized on the diverse contributions that GIS can provide at the macro level (the home delivery routing system) and the micro level (warehouse routing system).

(10 marks)
Caselet 1
Read the caselet carefully and answer the following questions:
2. What type of information systems is being implemented by Red Flowers? (5 marks)
3. How will such systems benefit Red Flowers, its florists and consumers? (5 marks)
A nationwide florists’ network is hoping that a new web-based system will speed orders to their customers. Red Flowers Ltd. recently started rolling out the system, an overhaul of an old system which used direct dial-up modem links that florists used to download orders. The new network lets florists log in over the Internet and receive orders and queries in real time from Red Flowers at www.redflowers.com. Florists can then ask questions about orders, such as whether delivery times can be changed or certain flowers substituted.For Red Flowers, the system means florists can check on orders faster. For instance, florists are encouraged to automatically confirm order deliveries over the system. If they do, they receive Rs. 10 back on the order. Local florists pay Rs.20 for each order they receive from Red Flowers. So when customers call Red Flowers to find out if a delivery has been made, the information is already in the system, and it is easy for florists to answer customer’s questions.Red Flowers is also in the process of adding electronic mail and chat capabilities to its systems. That will let florists communicate with one another about design, marketing, and business ideas. The company plans to offer computer-based training and lectures in the near future. And the company hopes to test the chat-based customer service.The idea behind this is to let consumers log on to the Red Flowers website, go to a private chat room, ask about ordering, and receive a real time answer from a Red Flowers customer service representative.Customers can also email their queries. But even with a usual two-hour response time, many time pressed people ended up calling with their questions as well. That means two different representatives answered the same question. With 35 percent of Red Flowers’ consumers seeking delivery the same day, valuable time can be saved by offering realtime answers to consumers who are about to plan an order.
4. There are differing views on the role of Information system in the enhancement of productivity in Business. Explain your views on this. (10 marks)

Read the caselet carefully and answer the following questions:
5. How did the implementation of a decision support system(DSS) help Frito-Lay overcome a slump in sales? (10 marks)
Frito-Lay chips experienced a major slump in the San Antonio and Houston supermarkets and no single reason could be attributed to this. The corporate marketers at Frito-Lay accessed their decision support system and identified that a regional competitor had introduced EI Galindo, a white-corn tortilla chip. In spite of the fact that the competitor did not have the resources to advertise extensively, the demand for its product increased through ‘word of mouth’ and resulted in the allocation of expanded shelf space for its product.Frito-Lay then developed a decision support system (DSS) that gathered data from supermarkets on a daily basis. The DSS scanned the data for information about local and regional trends. This helped Frito-Lay identify problems and opportunities in particular markets. Using the DSS, Frito-Lay could track the latest changes in sales. This information was used to respond quickly to market situations in a more proactive manner. When a competitor began a major promotional campaign, the results were identified almost immediately and a counter program could be launched. Also, Frito Lay’s new sales programs could be tracked and adjusted in response to customer purchases.

Section B : Problems/Caselets (50 Marks)
Caselet 1
Read the caselet carefully and answer the following questions:
1. Discuss the pros and cons of Plastic India Ltd. present structure of concentrating data department wis(e). (7 marks)
2. What are the problems Plastic India Ltd. might face while amalgamating the company’s data into a single database? (6 marks)
Plastic India Ltd. manufactures a wide range of plastic mouldings. The mouldings are used in diverse products such as motor vehicles, garden furniture and children’s toys. In order to serve this variety, there are six different sales departments, one manufacturing department and an ordering department. A separate IT department provides basic IT services to all the departments.Each department in the company has its own computerized records and databases. The IT department has been very successful in meeting the IT system requirements and providing high quality service to each user department in the past.
Plastic India Ltd. now plans to set up a centralized sales database that every user department can access. The database is intended to be very comprehensive, which will include among other things, details of goods, customers and debtor analysis. This would mean that the individual databases in each department will have to be amalgamated into this central database.
Caselet 2
Read the caselet carefully and answer the following questions:
3. Explain how IEL could improve its procedures to:
i. Ensure that only authorized sales reps have access to the main computer and
ii. Check that the data is completely and accurately transferred between the portable computers and the main court. 4. i What process could IEL use to include the daily order data within B&B’s MIS
ii. Indicate the various outputs that would be expected from the MIS to assist the senior management in decision-making. (7 marks) Indian Explosives Ltd. (IEL) sells industrial explosives which are used in tunneling, road building and demolishing of old buildings. IEL produces more than 500 types of explosives and related accessories.These explosives are sold to customers by highly trained sales representatives. In a typical transaction, each sales rep visits a customer site, ascertains the customer’s requirements and finally confirms the goods availability and lead time using his portable computer. The orders can be complex, involving many different types of explosives and related accessories.
At the end of the day, each sales rep links his computer to the company’s main database. Order details are transferred to the main computer, while updated stock balances are downloaded and are ready for use for the next day. In spite of the fact that the sales reps’ information may not be current, stockouts are infrequent.Every evening, after all the sales reps have fed the data to the main computer, the information is analyzed, production schedules are produced and the company’s management information system (MIS) is updated. Each rep logs on again in the morning and downloads a copy of the updated MIS.
5. “Although Information Systems have provided enormous benefits and efficiencies, they have also created new problems and challenges, of which managers should be aware of”
Discuss the benefits and the negative impacts of Information Systems. (10 marks)
Caselet 3
Read the caselet carefully and answer the following questions:
6. What are the business benefits of Reach’s intranet? (6 marks)
7. How does Reach’s extranet help strengthen its ties with its agents? (6 marks)
Reach Group, a Rs 3000 crore diversified property and casualty insurer, largely bypassed client/server technology on its way to the intranet. It did so partly because of the insurance industry’s conservative stance on technology.
However, the intranet’s simple application deployment and its potential as a competitive business tool drew Reach’s attention. The web provided Reach with the opportunity to distinguish itself with better, more informed services in an otherwise mature market. That meant a way to strengthen ties with its independent agent network. “This has always been a relationship business,” says the director of collaboration solutions.
RealNet, Reach’s first intranet application, was an enterprise wide risk management application that went up last year. It allows over 900 customer service representatives to track the account status and identify risk exposures by consulting a reference database of 40,000 policies and information from content experts on specific types of litigation or claims awards. Users make predefined queries, which offer 10 to 20 variables, against a SOL Server database; that in turn accesses a DB2 database on the mainframe.
When this system worked well, Reach developed an extranet application for agents selling worker’s compensation insurance. In insurance, where the name of the game is getting quick quotes, Reach’s extranet guarantees response time of 10 minutes or less, compared to hours or days in the old way. The company is also planning an extranet admission system for worker’s compensation claims to streamline a costly process bogged down by paperwork.
And for its top customers, Reach is considering adding a premium service extranet involving virtual private networks to get around the uncertain performance of public networks.

Section B : Caselets (50 Marks)
Caselet 1
Read the caselet carefully and answer the following questions:
1. What business problems were solved at Visa-Pro India by linking call centers and product databases? (6 marks)
2. What business benefits does Visa-Pro India expect from this approach? (7 marks)
Visa-Pro India expected its call center agents to answer customer queries quickly, completely, and politely. But as the systems that the agents used couldn’t find al the answers a customer was sometimes transferred to several operators before all his questions were answered.
In 1995, Visa-Pro India increased the training for its call center agents enabling them to have more information on a range of products to reduce the number of call transfers. But it didn’t work. To increase customer satisfaction, Visa-pro India is changing its approach. It is using a software that links its eight call centers and a variety of product databases so an agent can answer questions without transferring the call and soon, agents will be able to interact with customers via email and the Internet. Visa-Pro India recently chose a Customer Communications Solution software and is rolling it out to a total of 800 agents in eight call centers across India. Once the system is in place, a customer will be able to call one agent about any of Visa-Pro India’s 8 credit-card and other financial products.
Instead of transferring a customer to a different operator for each product, the new software will give each agent access to eight different product databases. The new approach will help Visa-Pro save Rs.30 million annually on its call center budget.
3. “Merely designing an EIS does not ensure its success.” What are the various barriers that prevent the effectiveness of an EIS? (12 marks)
Caselet 2
Read the caselet carefully and answer the following questions:
4. Why was the implementation process an easy one for South India Shipping corporation Ltd.?
(6 marks)
5. What are the advantages of implementing financial software? (7 marks)
Companies generally purchase software and then customize it to meet their customer’s needs. But sometimes a company may have to change its business processes to conform to a software package. In line with a company-wide decree to move from mainframes to client/server computing, South India Shipping Corporation Ltd acquired R/3 financial software modules from Germany’s SAP AG. South India Shipping corporation Ltd is one of the world’s leading global container transportation companies. It has 100 offices in about 40 countries. The shipping major owns and charters about 34 container vessels deployed in 30 liner services carrying more than 1 million containers worldwide every year. SAP met the shipping company’s requirements for handling its international customers. With this software, customers can choose a particular currency for payment, the country in which they want to pay the bill, and identify the party that will pay-the shipper or the consignee. Adapting the shipper’s existing processes to suit the standard accounting modules of SAP was easy because the company wanted to make changes to these processes. The accounting function also reduced the number of employees from 100 to 70 with the help of process reengineering. The different part of the global implementation of the R/3 financial modules was not the roll out but the design phase that preceded it. During the design phase, the company invited representatives from its offices in various countries and continents to participate. South India Shipping corporation Ltd. also hired project consultants and used the consultancy’s project management methodology to document the design process. The implementation of the R/3 financial modules was started in Chicago. Then the company operated on country and module by module as it rolled out R/3 financials across its overseas offices.
