ITPEC FE Subject A April 2026 Question 42
The functional size of a new system was estimated to be 500 function points (FPs). Apart from development, the project requires 10 person-months in total for installation of the system and education of developers. Additionally project management requires 10% of the total person-months of development, installation, and education. How many person-months are required in total for this project? Here, the productivity in development is 10 FPs per person-month.
Explanation
66 person-months — compute the development effort, add the fixed work, then add 10% of that sum for management.
- •Development: 500 ÷ 10 = 50 person-months
- •Installation and education: 10 person-months (given)
- •Subtotal: 50 + 10 = 60 person-months
- •Project management: 60 × 0.1 = 6 person-months
- •Total: 60 + 6 = 66 person-months
Answer (d)
Why not others:
- •(b) 60 — stops at the subtotal and leaves out the project management effort
- •(c) 65 — takes 10% of development only, 50 + 10 + 5, although the question bases it on development, installation and education together
- •(a) 51 — 50 + 10 × 0.1: development plus 10% of the installation and education work, dropping those 10 person-months themselves
Key rule: Check what a percentage is taken of; an overhead on "the total of" several activities is computed last, after they are summed.
