Hello

Can someone help me resolve this question? how do I tackle these types of questions on the PMp exam?

You are trying to determine whether or not to conduct 100% final system tests of 500 ground-based radar units at the factory. The historical radar field failure rate is 4%; the cost to test each unit in the factory is $10,000; the cost to reassemble each passed unit after the factory test is $2,000; the cost to repair and reassemble each failed unit after factory test is $23,000; and the cost to repair and reinstall each failed unit in the field is $350,000. Using decision tree analysis, what is the expected value if you decide to conduct these tests?

$5.5 million
$5.96 million
$6.42 million
$7 million

Thank you

Farid

Let me know if it is ok to post the questions I found difficult to resolve - I can surely provide the sources as well.

Hi Farid,

I think the correct answer is $6.42 million the details as below:

1- 96% pass the test = cost of testing = 96% * 500 unit * 10k = 5M
2- cost to resemble passed units = 96% * 500 unit * 2k = .96 M
3- cost to resemble and repair each failed unit after the factory test = .04* 500 unit * 23k = .46 M

so the total cost of to conduct the tests is 5M+.96M+.46M = 6.42 million

and the cost of not performing the test is "the cost to repair and reinstall each failed unit in the field" which = 0.04% * 500 * 350 K = 7 million.

so in this case conducting the tests would be the best option (but this is not part of the question :) )

other thought would be helpful as well.
