DECISION MAKING....
As Tim Cook picks up the leadership of Apple from Steve Jobs, he faces a significant ethical dilemma in Wuhan in a supplier’s company Foxconn, where workers threaten suicide in protest over their working conditions.
Details: Around 150 Chinese workers at Foxconn, the world’s largest electronics manufacturer, threatened to commit suicide by leaping from their factory roof in protest at their working conditions. The workers were eventually coaxed down after two days on top of their three-floor plant in Wuhan by Foxconn managers and local Chinese Communist party officials.
Grievances at Foxconn:
overworked employees
unsafe working conditions.
long working hours
under-age employees
chemical hazards in a bid to keep low costs of production
Irony: A number of Apple products have been cited as ‘game changers’ – products that have helped to change how we use technology to live our lives – in stark contrast, it seems that the workforce at Foxconn that helps to create these Apples products survives, and sadly tolerates a rather mundane existence. Loyal Apple consumers crave for their Apple products. However, it appears there is a darker, more un-savoury side to how Apple products make it to our shelves.
Tim Cook has promised to resolve the situation and not let things tarnish Apple’s image.
What should be Apple’s action keeping in mind the welfare of Chinese workers?
a. Initiate an aggressive program of paying component suppliers and contract manufacturers more in exchange for transparency, worker welfare and environmental safeguards.
b. Warn Foxconn with, “We will only buy products from you that have been made following the law,” and if the problem persists, move manufacturing out of China.
c. Take a hands-off approach to worker welfare.
d. Aggressively chip away at the problems associated with contract manufacturing with a program of iterative improvement, higher standards, constant audits and growing transparency.

XAT 2014:
Krishna Reddy was the head of a pharmaceutical company that was trying to develop a new product. Reddy, along with his friend Prabhakar Rao, assessed that such products had mixed success. Reddy and Rao realized that if a new product (a drug) was a success, it may result in sales of 100 crores but if it is unsuccessful, the sales may be only 20 crores. They further assessed that a new drug was likely to be successful 50% of times. Cost of launching the new drug was likely to be 50 crores.
Now, Reddy and Rao were in a quandary whether the company should go ahead and market the drug. They contacted Raj Adduri, a common friend for advice. Adduri was of the opinion that given the risky nature of launch, it may be a better idea to test the market. Rao and Reddy realized test marketing would cost 10 crores. Adduri told them the previous test marketing results have been favorable 70% of times and success rate of products favorably tested was 80%.Further, when test marketing results were unfavorable; the products have been successful 30% of the times
37. How much profit can the company expect to make if the product is launched after favorable test marketing results.(assume there are no additional costs)?
38. What is the probability of product failure if Reddy and Rao decides to test market it?

Recently, many critics of the U.S. government have pointed out that this country is the only industrialized nation without a national vaccine laboratory and suggested that this lack makes the American public more vulnerable than other advanced nations to diseases such as avian flu or other flu epidemics. When asked at a press conference, a government official said these critics were disloyal and thus wrong about the public’s vulnerability. To support his claim, he cited the international pre-eminence of American doctors and hospitals as well as the middle ranking of the United States among United Nation member nations in the health categories of infant mortality, life span, and nutrition. He also added that all of the Europeans that he knew preferred to undergo major medical treatments in the United States rather than in the socialized medical systems in place in their home countries. All of the following are flaws in the official’s logic EXCEPT:
