The number of function points of a proposed system is calculated as 500. Suppose that the system is planned to be developed in Java and the LOC/FP ratio of Java is 50. Estimate the effort (E) required to complete the project using the effort formula of basic COCOMO.
Given below : E = a(KLOC)b Assume that the values of a and b are 2.5 and 1.0 respectively.
Answer:Option III Easy Explanation by SamagraCS Team:Definition:Basic COCOMO Model
The basic COCOMO model gives an approximate estimate of the project parameters.
The basic COCOMO estimation model is given by the following expressions:
Formula,Effort = a∗(KLOC)b // Formula for Calculate Effort,
Tdev = c∗(Effort)d // Formula for Calculate Development time in month.
Let’s Solve the Problem,
Given Parameters is:Total Function Point =500 // Function point means No. of
Function or Modules in Projects,
Each function point have approximate lines of code (LOC) = 50.
So Total LOC=500 X 50 = 25000.
Lines of code(LOC)=25000,
We can write it KLOC = 25K,Multiplicative value 'a' = 2.5,
Exponential value'b' = 1.0.
Now put in the formula:
Basic COCOMO formula for Effort = a(KLOC)b = 2.5×(25)1.0 =2.5 x 25
=62.5
Now Effort Value is = 62.5 Person Month.
So, Option(III)is correct.
