Question

Assume that the size of an embedded s/w product has been estimated to be 25,000 lines of source code. Assume that the average salary of software be Rs. 22,000/- month. Determine the effort required to develop the software product and development time. Also calculate cost.

Answer 1

Developing a software is never been easy. Neither the cost of making it is less. On an average if the source code cosists of 25k lines of coding. Then an average software developer with high skills can develop it within 3 months approximately if he works for 12-15 hrs a day. And the customer who is demanding to make it, has to pay 1.5-2 lakh Indian rupees.

Answer 2

The effort required to develop the software product is 71 Person Month and the time taken to develop the product is 13 months.Also the cost required to develop the product is estimated to be Rs.2,86,000.

Given:

No:of lines of source code = 25000.

Average salary of the software developer  = Rs.22000/month.

To Find:

The effort, time, and cost to develop the software product.

Solution :

Step 1:Calculating the effort.

The effort can be determined from the expression,

$effort = a * (KLOC)^{b} person month.$

Where,

KLOC is the lines of code in thousands.

a ,b  are the product type with organic values 2.4 and 1.05.

Now substituting the corresponding values we get,

$effort = 2.4(25)^{1.05}$

Calculating it we get,

$effort =71 person month.$

Step 2:Calculating the time.

The time can be calculated from the expression,

$Time = c(effort)^{d} months$

Where c =  2.5 and d = 0.38.

So,

$Time = 2.5 * (71)^{0.38}$

$Time = 13 months$

Step 3: Calculating the cost.

We know that,

Development cost of the product = NO:of months x salary/month.

→Development cost of the product = 13 x 22000

→Development cost of the product = Rs.2,86,000.

Therefore, the effort, time and the cost required to develop the software are 71 person month,13 months and Rs.2,86,000
