Ratan Tata and his team faced “humiliation” when they went to sell the
group’s fledgling car business to Ford in 1999, but came back to “do a big favour” just nine years later by taking over the American giant’s marquee
brands Jaguar and Land Rover.
“They told us ‘you do not know anything, why did you start the passenger car
division at all’. They said they will do us a favour by buying our car division,”
a Tata Group veteran said while recalling a meeting of Ratan Tata and other
top executives with Ford officials in Detroit in 1999.
The Tata Motors team decided to return to New York the same evening and
Ratan Tata, then the group chairman, was sombre throughout the 90-minute
flight, said Pravin Kadle, who was part of the team at that time and now heads
Tata Capital.
“This was in 1999 and in 2008, the same Ford’s JLR was bought by us. Ford
chairman Bill Ford thanked Tata, saying ‘you are doing us a big favour by
buying JLR’,” Kadle said, to a thunderous applause at an awards function on
Thursday night.
What type of leadership theory would best explain this scenario? Explain with
justification?

Suppose you own a plumbing repair business and employ 15 plumbers. You are interested in estimating the difference in the average number of calls completed per day between two of the plumbers. A random sample of 40 days of plumber A’s work results in a sample average of 5.3 calls, with a population variance of 1.99. A random sample of 37 days of plumber B’s work results in a sample mean of 6.5 calls, with a population variance of 2.36. Use this information and a 95% level of confi dence to estimate the difference in population mean daily efforts between plumber A and plumber B. Interpret the results. Is it possible that, for these populations of days, the average number of calls completed between plumber A and plumber B do not differ?

Putting It Together: The V-2 Rocket in London In Thomas Pynchon’s book Gravity Rainbow, the characters discuss whether the Poisson probabilistic model can be used to describe the locations that Germany’s feared V-2 rocket would land in. They divided London into 0.25-km2 regions. They then counted the number of rockets that landed in each region, with the following results:

(d) A total of  rockets was fired. Determine the expected number of rocket hits by computing “expected number of rockets” , where  is the probability of observing that particular number of hits in the region.

(e) Conduct a goodness-of-fit test for the distribution using the  level of significance. Do the rocket hits appear to be modeled by a Poisson random variable?

Breezy Company

(This case was prepared by Elizabeth Morris, Lehigh University.)

Breezy Company of Bethlehem, Pennsylvania, is a small wholesale distributor of heating and cooling fans. The company deals with retailing firms that buy small-tomedium quantities of fans. The president, Chuck Breezy, was very pleased with the marked increase in sales over the past couple of years. Recently, however, the company’s accountant informed Chuck that although net income has increased, the percentage of uncollectibles has tripled. Due to the small size of the business, Chuck fears he may not be able to sustain these increased losses in the future. He has asked his accountant to analyze the situation.

Background

In 1998, the sales manager, John Breezy, moved to Alaska, and Chuck hired a young college graduate to take over the position. The company had always been a family business and, therefore, measurements of individual performance had never been a large consideration. The sales levels had been relatively constant because John had been content to sell to certain customers with whom he had been dealing for years. Chuck was leery about hiring outside of the family for this position. To try to keep sales levels up, he established a reward incentive based on net sales. The new sales manager, Bob Sellmore, was eager to set his career in motion and decided he would attempt to increase the sales levels. To do this, he recruited new customers while keeping the old clientele. After one year, Bob had proved himself to Chuck, who decided to introduce an advertising program to further increase sales. This brought in orders from a number of new customers, many of whom Breezy had never done business with before. The influx of orders excited Chuck so much that he instructed Jane Breezy, the finance manager, to raise the initial credit level for new customers. This induced some customers to purchase more.

Existing System

The accountant wrote up a comparative income statement to show changes in revenues and expenses over the last three years, shown in Exhibit A. Currently, Bob is receiving a commission of 2 percent of net sales. Breezy Company uses credit terms of net 30 days. At the end of previous years, bad debt expense amounted to approximately 2 percent of net sales.
As the finance manager, Jane performs credit checks. In previous years, Jane had been familiar with most clients and approved credit on the basis of past behavior. When dealing with new customers, Jane usually approved a low credit amount and increased it after the customer exhibited reliability. With the large increase in sales, Chuck felt that the current policy was restricting a further rise in sales levels. He decided to increase credit limits to eliminate this restriction. This policy, combined with the new advertising program, should attract many new customers.

Future

The new level of sales impresses Chuck and he wishes to expand, but he also wants to keep uncollectibles to a minimum. He believes the amount of uncollectibles should remain relatively constant as a percentage of sales. Chuck is thinking of expanding his production line but wants to see uncollectibles drop and sales stabilize before he proceeds with this plan.
