What is the use of COCOMO model?
Show Hint
The middle two letters of COCOMO stand for the thing it estimates.
Updated On: Jul 2, 2026

- Estimating software development costs
- Software validation
- Estimating the duration of the project

The Correct Option is B
Solution and Explanation
Step 1: COCOMO is the Constructive Cost Model. Its name already points to cost.
Step 2: It estimates effort in person-months from the size of the software, usually in thousands of lines of code (KLOC). Effort then converts to development cost.
Step 3: The basic form is effort E = a times (KLOC) raised to power b, so E = a (KLOC)^b. From effort you derive cost and, separately, schedule.
Step 4: While COCOMO can also give a rough schedule, its primary and defining purpose is estimating software development effort and cost. Managing projects and validation are different activities.
So the answer is option B.
