Given a project that uses the COCOMO model with an estimated effort of 2000 person-months and a productivity rate of 5 person-month per KLOC, what is the estimated size of the project in KLOC ?
400
COCOMO relates effort (person-months) to size (KLOC). Here the rate is stated as effort per unit size, 5 person-months for every KLOC, so size is the total effort divided by the effort needed per KLOC.
Step 1 — \(\text{Size} = \dfrac{\text{Effort}}{\text{Effort per KLOC}}\).
Step 2 — \(\text{Size} = \dfrac{2000}{5} = 400\) KLOC.
Step 3 — Check: 400 KLOC × 5 person-months per KLOC = 2000 person-months, which matches the given effort.
200 KLOC would need 10 person-months per KLOC, 100 KLOC would need 20, and 50 KLOC would need 40; none fits the stated rate of 5 person-months per KLOC.
400 option is correct.
