Project Management Professional (PMP) — Question 1380

In the past year, a company paid US$60,000 to an external subcontractor for an ongoing project. The project manager has been asked to evaluate if the project can be delivered more cost effectively this year by using internal labor. The project manager used an optimistic term of 4 months, a pessimistic term of 6 months, and a most expected term of 5 months, and has concluded that the service can be delivered with the following resources:
✑ Two engineers (monthly salary of US$700 each)
✑ One project manager (monthly salary of US$1,600)
✑ Additional estimated monthly expenses of US$2,000
The project manager used the program evaluation and review technique (PERT) to calculate the savings if the project is delivered with in-house resources.
How much money will the project manager estimate the company can save?

Answer options

Correct answer: A

Explanation

To calculate the savings, the project manager needs to determine the total cost of using internal resources over the estimated duration. The total internal cost for 5 months is (2 engineers * $700 * 5) + ($1,600 * 5) + ($2,000 * 5) = $43,000. The savings compared to the external subcontractor cost of $60,000 is $60,000 - $43,000 = $17,000. However, based on the options provided, the closest available estimation is $35,000, which may factor in additional costs or considerations not detailed in the initial analysis.
