    PMP · Question 41 · Task 11: Plan and manage procurement

    A project manager is deciding whether to build a solution in-house or buy it. Building it costs $50,000 upfront plus $1,000/month maintenance. Buying it costs $10,000 upfront plus $3,000/month subscription. At what month do the costs break even?

    Answer options:

    A.

    10 months

    B.

    15 months

    C.

    20 months

    D.

    25 months

    How to approach this question

    Set up the equation: Cost A = Cost B. Solve for M (months).

    Full Answer

    C.20 months✓ Correct
    Task 11 involves Make-or-Buy analysis. You save 40k upfront by buying, but lose 2k/month. 40k / 2k = 20 months to break even.
