Q.7 Pair programming is an agile software development technique in which two programmers work together at one work station. One types in code while the other reviews each line of code as it is typed in. The person typing is called the driver. The person reviewing the code is called the observer. The two programmers switch roles frequently (possibly every 30 minutes or less). Suppose that you are asked to build a system that allows remote pair programming. That is, the system should allow the driver and the observer to be in remote locations, but both can view a single desktop in real-time. The driver should be able to edit code and the observer should be able to “Point” to objects on the driver's desktop. In addition, there should be a video chat facility to allow the programmers to communicate. The system should allow the programmers to easily swap roles and record rationale in the form of video chats. In addition, the driver should be able to issue the system to backup old work.

ENGLISH FOR ACADEMIC PURPOSES-II (EAP-IIB)



Q.1 Read the passage and answer the following questions:A CURE FOR THE COMMON COLD?The average person comes down with three colds a year, each lasting for about nine days. There is still no cure but the following advice may help. Take time off work, because your body will fight off the cold virus better if it is well rested. However, if you have to work, avoid close contact with your co-workers as the virus is contagious. Wash your hands frequently or use an alcohol-based disinfectant gel. Non-sedating allergy medications, which you can buy from a chemist, can decrease drowsiness and also alleviate the problems of a runny nose, watery eyes and blocked sinuses. As soon as you feel a cold coming on, boost your fluid intake. Water or juice is ideal but hot herbal teas with lemon will help thin mucus and expel it from the body. A warm gargle with salt water will relieve a scratchy throat by reducing inflammation and clearing mucus and irritants. It also flushes out bacteria and viruses so it can be used as a preventative measure as well. The warm moisture generated by a hot shower or bath will soothe and clear nasal passages. Inhaling steam over a bowl of hot water relieves congested sinuses, too. For a tickly cough, the latest research suggests that honey, either straight from the jar or dissolved in a hot drink, works as well if not better than costly lozenges and sprays. A good diet is essential for a quick recovery, so start the day with a healthy breakfast including vitamin C in the form of fresh fruit or berries. For lunch, chicken soup is good, but be sure to add chunks of lean chicken meat, for protein helps build immune cells. Not only is this the perfect comfort food but it has been proven to be medicinally beneficial. For dinner, a spicy curry makes a good decongestant and some ingredients (ginger, garlic, chilli) are recognized as being anti-viral and anti-bacterial. A little light exercise is beneficial, as this will enhance your emotional wellbeing, but don’t attempt anything too strenuous. Finally, to recharge your body and regain your strength, you need a full eight hours’ sleepQuestion 1 – 17Complete the summary below.Choose NO MORE THAN TWO WORDS from the text for each answer. Write your answers in boxes 1-7 on your answer sheet.People usually get three colds every year. When sick, it is good to stay away from work because you need rest and you could spread the illness to 1 …………………. . Reduce 2 …………………. and cold symptoms by using medicines that you can buy from a pharmacy. Drink a lot and gargle with salt water to help clear your throat.

ENGLISH FOR ACADEMIC PURPOSES-II-B (EAP-IIB)


Note: All questions are compulsory. Marks are indicated against each question.

Q.1 Read the passage and answer the following questions:A CURE FOR THE COMMON COLD?The average person comes down with three colds a year, each lasting for about nine days. There is still no cure but the following advice may help. Take time off work, because your body will fight off the cold virus better if it is well rested. However, if you have to work, avoid close contact with your co-workers as the virus is contagious. Wash your hands frequently or use an alcohol-based disinfectant gel. Non-sedating allergy medications, which you can buy from a chemist, can decrease drowsiness and also alleviate the problems of a runny nose, watery eyes and blocked sinuses. As soon as you feel a cold coming on, boost your fluid intake. Water or juice is ideal but hot herbal teas with lemon will help thin mucus and expel it from the body. A warm gargle with salt water will relieve a scratchy throat by reducing inflammation and clearing mucus and irritants. It also flushes out bacteria and viruses so it can be used as a preventative measure as well. The warm moisture generated by a hot shower or bath will soothe and clear nasal passages. Inhaling steam over a bowl of hot water relieves congested sinuses, too. For a tickly cough, the latest research suggests that honey, either straight from the jar or dissolved in a hot drink, works as well if not better than costly lozenges and sprays. A good diet is essential for a quick recovery, so start the day with a healthy breakfast including vitamin C in the form of fresh fruit or berries. For lunch, chicken soup is good, but be sure to add chunks of lean chicken meat, for protein helps build immune cells. Not only is this the perfect comfort food but it has been proven to be medicinally beneficial. For dinner, a spicy curry makes a good decongestant and some ingredients (ginger, garlic, chilli) are recognized as being anti-viral and anti-bacterial. A little light exercise is beneficial, as this will enhance your emotional wellbeing, but don’t attempt anything too strenuous. Finally, to recharge your body and regain your strength, you need a full eight hours’ sleepQuestion 1 – 07Complete the summary below.Choose NO MORE THAN TWO WORDS from the text for each answer. Write your answers in boxes 1-7 on your answer sheet.People usually get three colds every year. When sick, it is good to stay away from work because you need rest and you could spread the illness to 1 …………………. . Reduce 2 …………………. and cold symptoms by using medicines that you can buy from a pharmacy. Drink a lot and gargle with salt water to help clear your throat.

PART-BQ.6 At a time when Kissan had become generic to tomato sauce, Maggi came in

with its sauces range. Maggi was the upstate new corner who came in with a loud aggressive national burst. It did not come in with one, but with a range of sauces in order to increase market share and expand the market by offering more usage occasions, bring consumers with different needs into the Maggi Sauces fold and weaning away users of different brands to Maggi. From a market share of 14% in 1985, Maggi Sauces now enjoys a share of about 50% of the market. The success of Maggi can be most importantly attributed to year-round media activity, and the humorous “it's different” campaign on Maggi Hot and Sweet sauce - this campaign had such an impact that it literally promoted the entire range of Maggi Sauces.However, today the situation is a little worrying – Kissan is actively promoting its ketchup, and multinational giant Heinz has launched Heinz Tomato Ketchup. The marketing team on Maggi Sauces, along with their advertising agency, needs to decide on what to do – should Maggi Tomato Ketchup be advertised separately, and if yes, then how?MARKET SIZEThe total sauces market size (tons) increase from 1985 – 1993 is as follows:

Year Tonnage Growth %1985 4900 ----1986 5850 19.31947 6800 16.21988 7000 2.91989 7500 7.11990 8000 6.71991 8800 10.11992 9350 6.21993 10500 12.3

THE MARKET PLACEThere has always been a presence of good additives in the Indian household. The traditional Indian main meal has chutneys and pickles as additives while the quasimeals, where snacks or ready to eat food is consumed, use sauce as an additive. Prior to Maggi Sauces launch in 1985 the scenario of the branded and unbranded sauces market was such that the Tomato ketchup was most popular in the market with 80% market leaving the remaining 20% for others.

IMAGE: SAUCES

THE BRANDThe Maggi Sauces brand has really been built by creating a new segment in 1989-90 by focusing on Hot and Sweet as a new specialty sauce. The most important aspects of Hot and Sweet werei) Brand Image: Young – Teenager, Ever changing, humorous, unpredictable

and “whacky”ii) Brand Positioning: Hot and Sweet was a tomato chili sauce that was

different.

Creative ObjectiveThe main task was to evoke laughter and thereby increase recall levels. Hot and Sweet was to become a brand that was the first to be considered in the purchase decision. The campaign was an unprecedented success as the market share went up to 50% in 1992; Hot and Sweet volume was up by 64% and made a 20% contribution to Maggi Sauces sales.

THE CONSUMERProfile of users and non-usersSauce is a product that cuts across all age groups and regions and therefore broadly the target group was All Adults with ₹2500/-+ MHI, in Class I+ towns. Users were those who have shifted from traditional Indian cooking to convenience cooking, where ready-to-use food items and additives are more readily used. The non-users were mainly those who prefer to prepare chutneys and homemade food additives rather than use sauces that are bought from the market.Who buys the Product, How and When?Sauces follow two purchase patterns, in regular sauce households; it is purchased at the beginning of every purchase cycle when monthly non-durable items are bought. The second group is of those households where sauce has an occasional use, it is usually an impulse purchase, from the local retailers and the main purchaser is the housewife with key influencers being children.The users can be further subdivided between Tomato Ketchup and specialty sauces such as Hot and Sweet. Tomato Ketchup is for all members of the family (MHI: Rs. 2500+) with the larger part of the consumption coming from children. The purchaser is however the housewife. Hot and Sweet is targeted at the young adult, modern, with MHI: ₹2500+. The purchaser could be the housewife or the male/female 'adult'.User’s attitude to category/brandTomato Ketchup is generally seen as fun to eat, adds flavor to all kinds of food, and is convenient to use. Users show low involvement, low brand loyalty, are very sensitive to price, appreciate 'premium' quality of Maggi, but are unwilling to pay very large price premium. On the other hand for Hot and Sweet, the frequency of consumption is lower with high band loyalty,

greater involvement, less price sensitivity and the user appreciates the unique taste and fun image of Maggi Hot and Sweet.

THE CURRENT SCENARIOThe growth of Hot and Sweet has slowed down and it can no longer offset lower growth on 400g Ketchup. On the other hand “Kissan” in the post Unilever takeover was able to increase its clout in the market-place through aggressive trade/consumer promotion inputs, new packaging – umbrella design across ranges. With the introduction of Heinz, there was a creative-shift from ‘Natural goodness’ to the thick tasty ketchup. Besides, all players introduced Hot and Sweet with ‘me too’ positioning, a serious threat to Maggi Tomato Ketchup.

a) Would you recommend that Hot and Sweet advertising should continue to support Maggi’s entire range, in view of increased competition? 5

b) If you have to develop new Tomato ketchup advertisements when the Hot and Sweet personality framework or develop a new Tomato Ketchup advertising on an entirely new platform, how would you go about it? Kindly illustrate the step-by-step approach you would follow, in any one category of your choice. 5

PART-BQ.6 CASE STUDY:

Airtel- The Story to Tell Through a Tale

The unprecedented growth in the mobile market is, perhaps, the most vivid facet of India's economic transformation since the mid-1990s. Mobile technology and services came to India just about a decade ago. In the early days, a mobile was seen to be a fashion statement for the rich. Today, it is accepted as a basic communication medium for all socio-economic segments. The Indian mobile market is, today, amongst the fastest growing and the most competitive in the world. Today India has approximately 100 million phone connections as on July 2005 (Source: Cellular Operators' Association of India and Association of Basic Telecom Operators). Out of which a little over half comprise of mobile subscribers? Airtel is one brand which has been instrumental in building up a vast subscriber base for itself. Airtel’s journey to leadership began in Delhi in 1995. Since then, Airtel has established itself pan-India targeting the entire population if India. In the last ten years Airtel has achieved many firsts and unique records: it was the first to launch nationwide roaming operations, it was the first to cross the one million and the five million customer marks. It was also the first to launch services overseas.

Evolution of Airtel as a BrandBharti Enterprises wished to transform itself from a Delhi Celluar operator to a pan Indian telecom operator. The company worked on a three-layered branding architecture:• To create specific brands for each of its services• Build sub-brands within each of these services• Use Bharti as the umbrella brandIn late-2002, Bharti Cellular Ltd. released a television commercial (TVC), which despite using the 'oft-repeated' celebrity endorsement route was

unusual in terms of its celebrity selection. Instead of using the usual movie stars/sports celebrities, it chose one of the country’s most successful music composers, A.R Rahman (Rahman) to promote its brand. The campaign attracted considerable media attention because this was the first time Rahman had agreed to do a television commercial and also because, Rahman had been paid ₹10 million for the campaign, a sum usually unheard of, for celebrity endorsers in India. The campaign received brickbats as well as bouquets in the media, both for the selection of Rahman and the TVC's execution. However, Bharti claimed to have scored an ace in terms of getting Rahman to compose five exclusive symphonies downloadable as ring tones for Airtel users. The TVC was a part of the brand repositioning and restructuring efforts for Airtel, as part of which, Bharti changed the brand's tagline in early-2002 from ‘Touch Tomorrow’ to ‘Live Every Moment.’The company also decided to undertake a comprehensive brand building program for the company and chose the slogan 'Unlimited Freedom' for the same. Commenting on these changes, company sources said, “Airtel’s brand identity and campaign will now have a new younger and international look and feel that builds on the earlier positioning.”Bharti’s massive media expenditure plans were no surprise, considering the fact that it was the largest cellular telecom company in the country – reaching over 600 million people in 16 (out of 29) states of India.. The Airtel brand (and the pre-paid card service brand, Magic) had top-of-the-mind recall amongst cellular phone users and enjoyed a leadership position in most markets. Industry observers primarily attributed it to Bharti's strong brand building and positioning strategies.

Amalgamation of the BrandsIt was September 2004, when BHarti undertook yet another repositioning exercise. BTVL decided to unify its entire gamut of telecom services under the Airtel Brand. This was done with an intention to be seen as an integrated telecom services player rather than just operating in the mobile space. It was an attempt to change the perception from “Airtel equals mobile” to “Airtel equals telecom”, and position Airtel as a complete telecom services brand. The company’s telecom were clubbed under four heads -- Airtel mobile services, Airtel telephone & broadband services, Airtel long distance services and Airtel enterprise services. With Airtel’s launch of ₹200 denomination cards in early 2005, Airtel has targeted the low usage segment, thereby offering services to cater to all segments. The strategy of Airtel is gradually shifting to the mass market. By targeting the segment of lower income group the brand is also changing its communication strategy from the premium brand or the brand for high class society to the brand for all segments. Airtel as a brand seems busy in building a mass franchisee for its target market. But Mr Sunil Mittal wants this brand to grow as the ‘Most Preferred and Respected Brand of India’. The sales driven communication has a limited ability to promote the brand as the ‘Most Preferred and Respected Brand of India’. One needs to use neutral methods of communication and public relation tools for building this level of brand recognition.

a) Analyze the brand image of Airtel and suggest suitable public relation and publicity strategy for making Airtel brand as the ‘Most Preferred and Respected Brand of India’. 10

PART-BCase study:

Rasna was first launched under the brand name ‘Jaffe’ in 1976, then relaunched as ‘Rasna’ in 1979, it failed to make any significant impact on the market. At that point of time ‘soft drink concentrate ‘was a little–known concept in India. To most people, soft drink meant aerated drinks marketed in bottles and consumed mostly outdoors. Branded soft drinks consumed at home were made from squashes and syrups.

The non – aerated soft drink market in India in the early 1980s was estimated at Rs. 130 million. Kissan, Roohafza, and Dippy’s were the major brands of squashes and syrups dominating the market. They accounted for about 74 percent share of the non–aerated drink market.

In 1983, the manufacturer Pauma Industries took over marketing and distribution from Voltas and shifted the account to Mudra Communications (Ahmadabad) which was not considered a top–notch agency at that time. Preliminary investigations by the agency suggested that consumer awareness for the Rasna Brand name was conducted by the agency to judge the awareness level and understand consumer perceptions about brand,

ascertaining the areas of dissatisfaction, if any. The agency also wanted to know consumer opinion on Rasna after trying out the brand for new days.

Research threw up valuable information. It was found that aerated soft drinks were perceived as costly and were not recommended for children. Squashes and syrups were also costly and had limited range of flavors. Home–made sherbets, besides being inconvenient to prepare, fell short of consumer expectation in taste and aesthetics. On trying Rasna, there was near unanimity in favor of its taste and ease of preparation. The brand was therefore positioned on the features of ‘taste’ and ‘convenience’. It was also felt that the brand had not been very successful in the past mainly because of ineffective advertising.

The strategy therefore focused on reawakening consumer interest in the brand and persuading them to try it at least once. Housewives in the age group of 20 plus and with household monthly income of Rs. 750 and more were targeted for the ad campaign. Children are usually the major influence in the purchase of eatables and beverages. The child route was therefore taken to promote the brand.

To avoid the product being perceived as expensive, a decision was taken to highlight economy without mentioning price. This helped in building a better image for the brand. Press and cinema were identified as the principal media for advertising. In 1984, it was decided to use television as the main medium for advertising because the television network in the country was rapidly expanding after the Asian Games. Two 30–second commercials a day on Doordarshan turned out to be so effective that within one year, the consumer off take shot up from Rs. 14.4 million in 1983 to Rs. 31.8 million in 1984. By the mid 1980s Rasna became a household brand name in India.

A research study conducted at the end of the summer of 1984 revealed that the spontaneous recall rate for the Rasna brand name amongst the target group was 80 per cent. Its share in the non–aerated drinks market increases from 6 per cent in 1982 to 17 per cent in 1984. Between 1983 and 1987 Rasna sponsored every relevant television programm such as Spiderman, Ek do teen char and Contact Quiz to further strengthen the brand equity. By 1987, Rasna captured a 40 per cent share of the total non–aerated soft drank market in the country.

Q.6 Read the case study carefully given above and answers the following questions:a) Ascertain the reasons for the success of Rasna brand. 5b) Discuss the role played by advertising and communication in building the brand. 5
