Scenario 4 Sharon Gillespie, a new buyer at Visionex, Inc., was reviewing quotations for a tooling contract submitted by four suppliers. She was evaluating the quotes based on price, target quality levels, and delivery lead time promises. As she was working, her manager, Dave Cox, entered her office. He asked how everything was progressing and if she needed any help. She mentioned she was reviewing quotations from suppliers for a tooling contract. Dave asked who the interested suppliers were and if she had made a decision. Sharon indicated that one supplier, Apex, appeared to fit exactly the requirements Visionex had specified in the proposal. Dave told her to keep up the good work. Later that day Dave again visited Sharons office. He stated that he had done some research on the suppliers and felt that another supplier, Micron, appeared to have the best track record with Visionex. He pointed out that Sharons first choice was a new supplier to Visionex and there was some risk involved with that choice. Dave indicated that it would please him greatly if she selected Micron for the contract. The next day Sharon was having lunch with another buyer, Mark Smith. She mentioned the conversation with Dave and said she honestly felt that Apex was the best choice. When Mark asked Sharon who Dave preferred, she answered, Micron. At that point Mark rolled his eyes and shook his head. Sharon asked what the body language was all about. Mark replied, Look, I know youre new but you should know this. I heard last week that Daves brother-in-law is a new part owner of Micron. I was wondering how soon it would be before he started steering business to that company. He is not the straightest character. Sharon was shocked. After a few moments, she announced that her original choice was still the best selection. At that point Mark reminded Sharon that she was replacing a terminated buyer who did not go along with one of Daves previous preferred suppliers. Ethical decisions that affect a buyers ethical perspective usually involve the organizational environment, cultural environment, personal environment, and industry environment. Analyze this scenario using these four variables.

: A small building contractor has recently experienced two successive years in which work opportunitiesexceeded the firm’s capacity. The contractor must now make a decision on the capacity for the next year.Estimated profits under each of the two possible states of nature are shown in the table below. The units are in P thousands. Which alternative should be selected if the decision criterion is: a. Maximax? b. Maximin? c. Laplace? d. Minimax regret?
Suppose that the management of Theme Park, Inc., has decided that there is a.35 probability that the motel’s application will be approved.a. If management uses maximum expected monetary value as the decision criterion, which alternative should it choose?b. Represent this problem in the form of a decision tree.c. If management has been offered the option of a temporary lease while the town planning boardconsiders the motel’s application, would you advise management to sign the lease? The leasewill cost $24,000.

DECISION THEORY. A man has to decide wheter to resign or not from his present position and apply for a job offering him 2x his present salary, that is if he passes the qualifying test. At present, he receives $3000 monthly compensation. The offer from another company has a condition that he will not be allowed to take the qualifying test, he will immediately be taken in and have a monthly pay of $6000. If he fails, he will remain jobless, he feels that his chance of passing the test is 35%. Suppose he decides to base his decision on expected value, should he resign from his post or not?

Decision Under Uncertainty: Suppose the management at somaya Inc., is considering changing the size (capacity) of its manufacturing plant. Management has narrowed the decision to three choices. The plant's capacity will be (1) expanded by 20 percent, (2) maintained at the current capacity, or (3) reduced by 20 percent. The outcome of this decision depends crucially on how the economy performs during the upcoming year. Thus the performance of the economy is the "state of nature" in this decision problem. For each possible decision and state of nature, the managers determine the profit outcome, or payoff, shown in the payoff matrix in table 1. Table 1 The Payoff Matrix for somaya Inc.
