Caselet 1
This case is based on an actual incident which took place in an Army Unit deployed in field area.
A part of a Battery (about 1/4 of an Artillery Regiment) was deployed in a snow bound high
altitude area of Kashmir. This was the first time, an artillery unit was deployed in an area with
roads and tracks still under development. Preparation of this area for such a deployment needed a
lot of digging for guns, pits for ammunition storage, living place of the personnel, slit trenches
and weapon pits for local defence against any possible enemy/terrorists’ attack on the position,
place for storage of rations, cook-house and communication trenches, etc.
The total strength of the party deployed there was
a) Officer - 1 (Second Lieutenant with about one year service)
b) Junior Commissioned Officer (JCO) - 1
c) Jawans - 40
The Battery Commander (BC) remained with the Regiment Headquarters at Srinagar (with the
remaining part of the Battery) as per the orders of the commanding Officer. These was a vehicle
with the part of the Battery which was deployed at high altitude to assist in the daily
administration of the troops like collection of ration, stores for preparation of defences, water, and
ferrying of personnel from one place to another. The vehicle could could go only upto a limited
number of places due to bad road conditions and step gradients. Only one driver was kept for this
vehicle to reduce administrative problems due to more number of personnel. The vehicle
completed about 35 to 40 kms. of running daily in its routine commitments.
The part had just been inducted about two weeks back. The defences were being prepared
which involved lot of effort in digging of hardened ground due to the cold winter months of
November. The defence stores were to collected, once the digging was complete, from another
Engineering Unit located about 5 kms. to the rear. The roads were treacherous; with a number of
stones and slides falling down occasionally during a drizzle due to precipitation in atmosphere,
there were steep gradients, narrow roads with sheer falls on one side due to the road having been
cut into the side of hills. The digging was complete by end November. In the month of December,
snow fall at that location was expected any time, as it had already started snowing in the higher
reaches and tops of mountains. The digging had been completed in a record time of two weeks.
The party under the stewardship of the young officer had done a commendable job.
In the first week of December, the only driver of the vehicle reported pain in the chest and
problem in breathing. He was evacuated by helicopter the next day with instructions to inform the
unit to send another driver for the vehicle. It took about three days for any one to reach this area,
with staying of two nights enroute in order to acclimatize by stages. The detachment was to be
without any driver for about three days. Another driver was detailed to proceed to this area, after
having been medically examined and found it. A day after the dispatch of the driver, the young
officer with this party arrived in the unit and reported that the vehicle had fallen from a hill-side
road and was completely damaged. The office was in a complete state of disarray and shock.
What actually had happened, goes something like this.
Examination Paper of Semester III
After the first driver of the vehicle was evacuated, the weather started turning bad and it
seemed that it was going to snow that day. The officer realised that in case of snow fall all the
efforts put in by the troops would go waste, if the dug-ins were not covered. Realising this, he
borrowed a driver of an ambulance from a local medical unit to direct his vehicle for collection of
defence stores. After the stores had been collected and dumped at the site of defences, the vehicle
was being driven back to the party’s location. Before it could reach this location, it had to
negotiate a dusty and steep track. At a steep climb the vehicle stalled and got switched off. All the
men got down, prevented the vehicle from reversing by putting stones behind the wheels and
started checking what had gone wrong.
After the check on the engine had been carried out, the bonnet cover slipped off the hands of
the driver while closing it and fell to closing position with a bang. Because of the jerk thus
created, the stones placed behind the vehicle slipped off. It was later discovered that there was
glassy smooth layer of ice under the thin layer of dirt which could not hold the stones firmly and
they slipped off, with the result, that the vehicle moved backward and toppled thrice and stopped
upside down because of the obstruction created by a big boulder. As thee was no one in the
vehicle, thee were no injuries to personnel. On close inspection by the officer, it was found that
the vehicle body, cabin, bonnet, steering wheel and two of the four wheels were badly damaged.
The officer, being quite young and inexperienced, could not ascertain the real condition of the
engine and chassis. He thought those too were damaged, whereas because of some providential
chance, the chassis and engine remained intact.
The BC was given the responsibility of getting the vehicle back to the unit. He was given a
vehicle fitter and recovery vehicle with a driver. The BC took two more Non-Commissioned
Officers (NCOs) and proceeded to the location to retrieve the vehicle, it took two days to reach
with a few hours of the last leg of the journey in complete darkness in that snow bound area with
treacherous slippery roads. On reaching the location, the Commanding Officer of the local unit,
who happened to be the Station Commander of the sector, expressed his unhappiness on their
taking such a great risk. With the assistance of all ranks of the unit, who came in willingly, it took
two days to get the vehicle out of the boulder strewn area on to a track. It was a minor military
operation in itself in the hostile terrain, and inclement weather of high altitude. The troops and
officer had a very good rapport with those of the local unit and there was not much of a problem
in getting the men of that unit to assist.
While coming back, the hazards of night journey were very obvious. There was a thick layer
of snow on the road with slope towards the khuds as layers after layers kept on accumulating,
freezing before the water could roll down the complete slope. There were steep falls on one side.
Both these phenomena, peculiar to hilly terrain, were not very discernible because of the
darkness. The headlights of the vehicles exposed very little. There were frozen nalas where the
vehicle would skid, aligning itself in the direction of the frozen nala, which tended to prove quite
dangerous at times. At such places, the few troops and officer available would get down , push
the vehicle to keep it aligned to the road and in turn slip down themselves on the frozen snow,
most of the times face-down , in an attempt to push the vehicle. Though the situation was quite
grave, it sometimes bordered on being humorous with everyone laughing spontaneously. At one
place, the BC pushing the vehicle to keep its tail and aligned to the direction of road , fell down,
slipped a few feet down the frozen nala and landed up head down in an frozen khud about five
feet deep. But for the direction of landing, the slip and fall could have proved quite dangerous.
There was complete silence. The vehicle was gently stopped on the snow itself, secured with
pegs along the wheels and rescue operation commenced for the ditch. There were several
humorous seamarks by the BC and the tension was relieved at once, with troops working on the
vehicle with renewed vigour and strength once again.
At another place, the recovery vehicle with the damaged vehicle behind it at suspension toe
slipped, but because of the dexterity of the driver, it was saved from going down a nala by putting
it on the left. The BC himself was in the recovery vehicle to give encouragement and moral
Examination Paper of Semester III
support to the driver, sharing all the risks which his troops were facing. He did all that the troops
did, while directing, controlling and executing. The party with the vehicle, reached the unit
location on the evening of the second day after starting from a high altitude area. The problem of
recovery of the vehicle being resolved, the question of enquiry into the cause of accident arose.
An enquiry into such an accident would have caused embarrassment to all those in authority in
the unit and also the officers and jawans of the sub-unit/battery. Meanwhile, the inspection of the
vehicle was carried out to assess the extent of damage. It was found that the engine and chasis
were intact and the rest of the items of the body or fitment were damaged, either lightly or
severely. To avoid embarrassment to the unit and loss to the exchequer, as well as in view of the
administrative difficulties, the BC decided to have the vehicle put on road with the units’ efforts
and at the earliest. Meanwhile, the cabin-hood of the vehicle had been purchased for about Rs 650
and was paid for by the BC, from his own pocket, thus setting an example to others. The JCO and
jawans were also keen to pay for other damages. The offer was appreciated but declined. The
Officer-in-charge of the local Army Workshop happened to be an officer with commendable
helping attitude, positive bent of mind and with an understanding of peculiarities and problems of
the area where such accidents were quite frequent and possible. When approached to assist, he
listened to the whole incident very sympathetically and promised to assist in whatever way he
could. This officer was a contemporary of the unit in a previous station and had excellent
relations and interaction with the unit. Some items were offered by the workshop officer and
replaced accordingly. The vehicle was made roadworthy again within a fortnight and put on road
for duty. All the enquiries were dispensed with and there was no loss of face by anyone at any
level. It is pertinent to mention that it had snowed in that location as soon as the recovery party
came out of the hills.
1. Which factors contributed to motivate the troops to go ahead for such a difficult task as
recovering a damaged vehicle from such a difficult and treacherous terrain and getting it
repaired in such a short time?
2. Which incidents indicate the importance of good interpersonal relationships with juniors,
peers and superiors and what is the importance of good interpersonal relationships?

Carrier Corp. is using data mining to profile online customers and offer them cool deals on air
conditioners and related products. By using services from WebMiner, Inc., the air-conditioning,
heating, and refrigeration equipment maker has turned more Web visitors into buyers, increasing
per-visitor revenue from$1.47 to $37.42.
Carrier, part of $26 billion United Technologies Corp., began selling air conditioners, air
purifiers, and other products to consumers via the Web in 1999. However, it sold only about
3,500 units that year, says Paul Berman, global e-business manager at the Farmington,
Connecticut, company. Not knowing just who its customers were and what they wanted was a big
part of the problem. “We were looking for ways to raise awareness [of Carrier’s Web store] and
convert Internet traffic to sales,” Berman says.
Last year, Carrier gave WebMiner a year’s worth of online sales data, plus a database of
Web surfers who had signed up for an online sweepstakes the company ran in 1999. WebMiner
combined that with third-party demographic data to develop profiles of Carrier’s online
customers. The typical customer is young (30 to 37), Hispanic, and lives in an apartment in an
East Coast urban area.
Examination Paper of Semester III
WebMiner matched the profiles to ZIP codes and developed predictive models. Since
May of 2002 Carrier has enticed visitors to its Web site, with discounts. When they type in their
ZIP codes, WebMiner establishes a customer profile and pops up a window that offers
appropriate products, such as multiroom air conditioners for suburbanites or compact models for
apartment dwellers. “It’s the first time we’ve intelligently delivered data-driven promotions,”
Berman says.
Online sales have exceeded 7,000 units this year, Berman says, compared with 10,000
units for all of last year. Carrier chose the WebMiner service because it was quick to implement
and is relatively inexpensive - $10,000 for installation and a $5 fee to WebMiner for each unit
sold, compared with 6-figure alternatives.
1. The DM application used by Carrier was one that was predictive in nature. Could a
descriptive model also be used? How would you use it, and what outputs would you except?
Would they be of any use to Carrier?
2. What other data-driven promotions could Carrier come up with using other data mining
techniques?
3. What manufacturing-driven applications can Carrier implement using data mining?
4. What finance-driven applications can Carrier implement using data mining?`

Caselet 1
New South Energy, a subsidiary of Calpine Corp., and Suez Energy North America has asked the Mississippi Public Service Commission to delay Entergy Corp’s purchase of the 480 – MW Attala plant. Entergy agreed in March to purchase the natural gas – fired plant located in Attala. Country, Miss., from Central Mississippi Generating Co., for $ 88 million. But it asked Cleco Corp., to purchase the transmission infrastructure associated with the plant. The two companies want the public service commission to require Entergy to go through the request for proposals process to show that the plant offers the best value to Mississippi ratepayers. “We do not necessarily oppose the acquisition. But what’s the rush?” a New South spokesman said. The price is good until next October, so New South and Suez are asking for proof that in today’s market it is the best deal for ratepayers. “They should let other bidders have a chance,” the spokesman said.
The Mississippi PSC held hearings on the sale of the plant on Wednesday.
Getting the sale approved immediately does have an advantage for Entergy. If it is approved before early February it will exempt the sale from the Federal Energy Regulations Commission’s jurisdiction. The energy bill signed by President Bush in August gives FERC jurisdiction over such asset – only sales beginning in February.
By separating the plant from the transmission infrastructure, the sale was exempted from FERC’s jurisdiction under current rules. FERC is more likely to look at whether the sale of the asset has market power or transmission implications.
The PSC’s staff said that based on information provided by Entergy, it appears the acquisition of Attala is in the public interest and represents a unique opportunity for Entergy to upgrade its aging generation fleet at a price that is in line with recent sales of similar units and below what it would cost to build a new unit.

It has concerns, however, over Entergy’s plan to recover the cost of the plant through rider to its existing power management schedule. “The recovery of each plant should be addressed individually,” the staff said.
The staff is also concerned about “piecemeal ratemaking,” meaning that certain costs are considered in isolation rather than looking at total costs. It cited concerns that Entergy would try to recover operations and maintenance costs under the rider when it is already included in base rates, and that certain revenues related to the newly acquired plant will not be considered when setting rates.
Questions
Q1. Write a note on ‘Piecemeal Ratemaking?
Q2. What are the advantages of the Acquisition of Entergy Corp’s by Mississippi Public Service Commission?

Electricity is a vital energy input for economic development of any country and helps to alleviate many of the concerns facing the world, today in a distinctive manner. It is available from various sources such as conventional and non – conventional sources at a reasonable cost. The electricity generation in India has indicated four times increase i.e., from 120.8 billion KWH in 1980 – 81 to about 650 billion KWH in 2004 – 2005. It is very interesting to note that among the conventional sources involved in the process of electricity generation, the share of thermal energy has been significant indicating the growth from 61.3 billion KWH to 700 billion KWH during 1980 – 81 to 2005. The other sources of energy i.e., hydro energy and nuclear energy have been playing an insignificant role in electricity generation. The basic input of electricity generation, i.e., coal is causing for many pollutants like sulphur dioxide, nitrogen oxide, carbon dioxide and particulate matter have a severe damaging effect on mankind and nature. Thus fuel substitution is very crucial for reducing the adverse impact on environment in the process of electricity generation. The non – conventional sources of energy like solar energy, wind energy, biomass, geothermal etc., can be used as substitute energies to electricity generation without any adverse impact on environment. Moreover, these renewable sources of energy are both economically viable and environmentally preferable alternatives to fossil fuels. Apart from this, the government also should involve in environmental matters and protect the public interest in order to maintain pollution free environment. A strong national energy policy and legislative acts should be formulated for a pollution free environment. The various alternative options if emphasized by the government, such as, adoption of energy efficiency measures, economic policies and technology can stabilize the environmental pollution over a period of time.

This a truly a ambitious project and a showpiece of co-operation between the state Government of Rajasthan, the Government of India, the World Bank and the Government of Germany getting together to strike a blow to renewable energy.
The project in question is a 140 MW Integrated Solar Combined Cycle (ISCC) power plant with a solar component of 35 MW and a combined cycle power plant of 105 MW in Jodhpur district in Rajasthan. The combined cycle plant will use naphtha as the fuel, and a back-up plant of 35 MW will also lend a helping hand when the sun is not shining.
The total cost of the project works out to eight hundred and seventy-one crore rupees- a hefty capital cost of six crore thirty lakh rupees per MW while a stand-alone naphtha based plant will cost less than four crore rupees a MW. The trick here is how the project is being financed to make it viable.
The Government of India will provide a grant of fifty crore rupees.
The Government of Rajasthan will pitch in with an equity contribution of fifty crore rupees and a loan component of two hundred crore rupees.
The World Bank through its Global Environment Facility will grant US dollars 49 million or two hundred and thirty-five crore rupees.
The Government of Germany will add a “cheap” long-term loan of twenty-five crore Deutsche Marks or five hundred crore rupees.

Total “aid” in terms of grants and easy loan works out to close to one thousand crore rupees for an eight hundred and seventy-one crore rupee project!
Most of the time, the “green” and “clean” showcase project will be running on naphtha, a dirty oil based fuel, which negates all that green activists stand for. That is simply because the sunlight won’t be around at the convenience of green activists. Of course, economists would be more concerned with the opportunity cost of using one lakh seventy thousand tones each year of naphtha in this “solar” energy project!

Q 1. How to Generate Solar Energy using Naptha? Explain?
Caselet 2
Energy plays a vital role in our day to day life. Energy consumption and production affect the local and global environment. Energy is mainly produced from fossil fuels and a sustainable development in the production of energy is a situation in which the future does not get harmed in any way. However, the use of fossil fuels will not help promote this much – longed – for sustainable development as fossil fuels when burned release a lot of energy into the atmosphere, which may lead to environmental damage.
The sustainable energy sources must be tapped to change the energy pattern used by the consumers, for which renewal energy sources like wind, sunlight and water need to be tapped and stored. The use of renewable energy is cleaner and safer for the environment. Various countries have started taking initiatives in building sustainable renewal energy resources, thereby, throwing open employment to the youth.
The adoption of renewable energy resources is difficult in poor countries due to lack of education, or inaccessibility of technology, or lack of institutional capacity for promoting renewable energy or lastly due to high financial costs. The environment of the youth can be roped in for the task of developing renewable resources after necessary coaching. Empowering the youth will help to reach a wider spectrum of the community in the development process of renewable energy resources.
The environment of the youth in such enterprises will tackle not only the issue of youth unemployment but will also promote environmentally sustainable renewable energy development. The rural youth need a conducive environment for the successful and continued implementation of renewable energy projects. In order to remote off –grid renewable energy, close and continuous engagement with local community members is essential. Thus, if the stakeholders are the ones who are developing and operating these enterprises, it will ensure viability, sustainability and effective operation in these enterprises.
The various renewable energy technologies available are not cost – effective and technically viable. However, most forms of renewable energy still have a significant way to go. The implementation of renewable energy projects can deliver clear benefits to developing countries provided they use efficient technologies. In this case, the technical know – how is invariably transferred from the experienced and developing countries to most of the less developed or developing countries.

Over the past two years Linux has spread like wildfire through corporate data centers. Companies
once dependent on expensive proprietary systems from Sun, IBM, or Hewlett-Packard have replaced
them with dirt-cheap Dell or no-name servers that are Intel powered and loaded with the Linux
operating system. Linux now runs almost 15 percent of all servers and is growing at about 23 percent
a year. And even mainframe systems have joined in, with IBM estimating that over 10 percent of its
mainframe sales are for running Linux applications.
Though PC users haven’t switched to Linux – less than 1 percent of all computers run Linux – a
2002 survey by CIO magazine found that almost 30 percent of chief technologists were considering
moving their companies’ PCs to a Linux PC operating system like Lindows. Wal-Mart, which began
selling Lindows-ready PCs on its website in September 2002, had such success with that offering
that by Christmas it was having trouble meeting demand. Almost every major PC electronics maker,
from HP in printers to Epson in scanners, is making sure it has Linux-compatible offerings. And Sun
has poured millions of dollars into its Star Office software suite, which gives Linux users programs
that work like – and more important, are compatible with – Microsoft PowerPoint, Word, and Excel.
Backed by technology titans such as Intel, IBM, Hewlett Packard, and Dell, Linux is just now
going mainstream. From DaimlerChrysler to Tommy Hilfiger – not to mention just about every
major brokerage on Wall Street – Linux is gaining ground. Coming from near zero three years ago,
Linux grabbed 13.7 percent of the $50.9 billion market for server computers in 2002. That figure is
expected to jump to 25.2 percent in 2006, putting Linux in the No. 2 position, according to market
researcher IDC. And get this: Starting in 2003, No. 1 Microsoft’s 59.9 percent share in the
backwards. Even the surprise but shaky assault on Linux by SCO in its suit of IBM is not expected
to slow the steady growth of Linux.
Meanwhile, Linux is finding its way into countless consumer-electronics gizmos, including Sony
PlayStation videogame consoles and TiVo TV-program recorders. “Has Linux come of age? The
answer is absolutely, positively, unequivocally yes,” says Steven A. Mills, group executive for IBM
Software.
How did Linux make the jump into the mainstream? A trio of powerful forces converged. First,
credit the sagging economy. Corporations under intense pressure to reduce their computing bills
began casting about for low-cost alternatives. Second, Intel Corp., the dominant maker of processors
for PCs, loosened its tight links with Microsoft and started marking chips for Linux; at the same time
a resurgent IBM made a $1 billion investment in Linux compatibility across its entire product line.
This made it possible for corporations to get all the computing power they wanted at a fraction of the
price. The third ingredient was widespread resentment of Microsoft and fear that the company was
on the verge of gaining a stranglehold on corporate customers. “I always want to have the right
competitive dynamics. That’s why we focus on Linux. Riding that were will give us choices going
forward,” says John A. McKinley Jr., executive vice-president for global technology and services at
Merrill Lynch Co., which runs some key securities trading applications on Linux.
Using open-source software like Linux is a no-brainer for many companies. It’s stable and can be
fixed easily if bugs appear, and you can’t beat the price. But some companies and government
organizations are taking their commitment to open source a step further by actively participating in
the open-source community that develops Linux. When their developers write patches, modifications

or new implementations of open-source software for in-house use, these organizations are releasing
that new code back to the open-source community, thereby assisting in the software’s ongoing
development.
What’s the payoff? It makes for better software. “If we find a bug or a problem, we’re interested
fixing that problem. We’re also interested in not fixing it again in the next version,” explains Robert
M. Lefkowitz, director of open-source strategy at Merrill Lynch & Co. in New York.
This is why Merrill Lunch sent the fixes it made to open-source software during one of its
projects back to the open-source community. “The way a typical open-source project works is that
there is a core team in the open-source community with direct access to modifying the code on its
central website,” Lefkowitz says. “People who want to contribute to that community submit their
code, which is looked at by a core team and integrated if found appropriate.”
For all contributions, Lefkowitz emphasizes the importance of creating a corporate policy with
help from the departments that could be affected by open-source involvement. At Merrill Lynch, an
eight-member Open-Source Review Board determines when contributing is appropriate.
1. Should businesses continue to switch to the Linux operating system on servers and mainframes?
Why or why not?
2. Should the IT departments of companies like Merrill Lynch contribute their software
improvements to the open-source community for products like Linux? Explain your reasoning?
Caselet 2
Ram construction and company’s manager like to determine the appropriate specification for a new
computer. The marketing department will use new computer to create multimedia presentations for
organization’s sales force. The marketing department will make these presentations available to
users both on the Internet and through DVDs.
Company manager had also informed Director that company’s information technology (IT)
department will support only PC-based computers and the Adobe Premiere Pro video editing DVD
designing software package. Company’s manager insists that Director specifications conform to
these standards in order to minimize long-term training and support costs.
