CAPM Practice: Demonstrate an understanding of project management planning

Total resource months = (3 developers × 6 months) + (1 designer × 3 months) + (1 tester × 4 months) = 18 + 3 + 4 = 25 resource months. This calculation helps determine resource capacity and cost planning.

**Why not A:** 13 resource months would result from incorrect calculation. The correct formula multiplies each resource count by its duration: (3x6) + (1x3) + (1x4) = 18 + 3 + 4 = 25, not 13.

**Why not B:** 5 resource months for 6 months ignores the need to multiply resource quantity by duration. Simply adding the headcount (3+1+1=5) without accounting for how long each works does not capture total effort.

**Why not C:** 14 resource months is an incorrect calculation. Applying the correct formula of quantity times duration for each resource type yields (3x6) + (1x3) + (1x4) = 25, not 14.
