 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A software company needs to develop a project that is estimated as 1000 function point and is planning to use JAVA as the programming language whose approximate lines of code per function point is accepted as 50. Considering a=1.4 as multiplicative factor, b=1.0 as exponential factor for the basic COCOMO effort equation and c=3.0 as multiplicative factor, d=0.33 as exponential factor for basic COCOMO duration equation. Apply COCOMO model and identify approximately how long does the project take to complete and average staff size required to complete this software on time.
 A 12 Month and 6 person B 13 Month and 6 person C 15 Month and 5 person D 13 month and 5 person
Explanation:

Detailed explanation-1: -Software projects under COCOMO model strategies are classified into 3 categories, organic, semi-detached, and embedded.

Detailed explanation-2: -Calculate the effort estimate by multiplying the initial estimate with all the multiplying factors i.e., multiply the values in step1 and step2.

Detailed explanation-3: -The basic COCOMO model assumes that effort and development time are functions of the product size alone.

Detailed explanation-4: -Person Required = effort/time a, b, c, d are constants and have different values for different models. Time is the time required to develop the product and the unit is months. And the effort is the total effort calculated that will be required to complete the work calculated in PM (Person Months).
