PK0-003 · Question #352
A project needs software. After analyzing the choices, it is determined that if made in- house, it will cost $100,000. However, if the software is purchased, the cost would be $25,000. After reviewing
The correct answer is C. $165,000. The Expected Monetary Value (EMV) for purchasing the software is calculated by summing the initial purchase cost and the probabilistic cost of required training and customizations.
Question
A project needs software. After analyzing the choices, it is determined that if made in- house, it will cost $100,000. However, if the software is purchased, the cost would be $25,000. After reviewing the successful implementations in the past, if made in-house, there is a 20% chance that $30,000 would be spent on bug fixes. If the software is purchased, there is a 70% chance that $200,000 in training and customizations would be required. Which of the following reflects the expected monetary value of purchasing the software?
Options
- A$106,000
- B$157,500
- C$165,000
- D$225,000

Why each option
The Expected Monetary Value (EMV) for purchasing the software is calculated by summing the initial purchase cost and the probabilistic cost of required training and customizations.
This value ($100,000 + 0.20 * $30,000 = $106,000) represents the EMV for making the software in-house, not purchasing it.
This value does not align with the correct EMV calculation for purchasing the software based on the provided data.
The EMV for purchasing the software is calculated as the initial cost plus the product of the probability and cost of the uncertain event. This is $25,000 (purchase cost) + (70% probability * $200,000 training/customizations) = $25,000 + $140,000 = $165,000.
This value appears to be a simple sum of the purchase cost and the potential training/customization cost without applying the probability ($25,000 + $200,000 = $225,000).
