a)
To determine: The sensitivity to the problem in terms of the probability estimate of 0.35.
Introduction: Decision making is the procedure of selecting choices by identifying a decision, obtaining information and evaluating alternative resolutions. Always, step-by-step decision making process can help to make more deliberate, and thoughtful decisions in the organization.
a)
Answer to Problem 8P
Explanation of Solution
Given information:
It is given that the lease of theme part is about to expire. The management should decide whether to renew the lease for another 10 years or relocate the motel. The details about the two alternatives are as follows:
| Options | Motel approved | Motel rejected |
| Renew | $500,000 | $4,000,000 |
| Relocate | $5,000,000 | $100,000 |
Determine the sensitivity of the problem:
The graph shown below contains the range of values of probability of approved motel where the alternative is optimal:
If the value is low, renewal is best with the highest expected value.
If the value is high, relocate is best with the highest expected value
Slope of renew:
Equation for renew:
Slope of relocate:
Equation for renew:
Determine the intersection between two lines:
It can be determined by equaling the equations of renew and relocate.
Optimal ranges are as follows:
Renew:
Relocate:
b)
To determine: The sensitivity to the problem in terms of the probability estimate of 0.45.
Introduction: Decision-making is the process that helps to make decision. It is the process of choosing a best alternative by evaluating many alternatives.

Relocate:
Conclusion: It is given that the percentage is 0.45 which is less than .4643. Hence, renew should be selected.
c)
To determine: The range of payoff for renew reject for the selected alternative.

Answer to Problem 8P
Explanation of Solution
Given information:
It is given that the lease of theme part is about to expire. The management should decide whether to renew the lease for another 10 years or relocate the motel. The details about the two alternatives are as follows:
| Options | Motel approved | Motel rejected |
| Renew | $500,000 | $4,000,000 |
| Relocate | $5,000,000 | $100,000 |
The estimated payoff except for $4 million and the probability of approval is 0.35.
Determine the payoff:
Renew:
X should be plugged in instead of 4,000,000 in the above equation
Relocate:
Equal the equations of renew and relocate to solve x:
Equations of renew and relocate should be equaled to determine the value of x.
The original decisions at payoff is $4,000,000 should be decreased to $2,523,077 for the decision to change from renew to relocate.
When x is $2,523,077, there would be indifference between renew and relocate.
When x is less than $2,523,077, the decision would be changed to relocate.

Direct threats to face in a negotiation include making ultimatums, criticisms, challenges, and insults (Thompson, 2019). A good example of face is when I go to the negotiation table with a counterpart that is known to be difficult or not as knowledgeable about the category as they should be, my approach wouldn't be to point out their weakness, I will respect their thought process, show consideration for their perspective, all while guiding the conversation in the direction of my intended negotiation strategy in hopes to achieve my desired outcome.
