Question

Firewall Project XT. Using the “complexity weighting” scheme and the function point complexity weighted table shown below, calculate the total function point count. Assume historical data suggest 6 function points equal one person-month and 7 people can work on the project. (Round the final answers to the nearest whole numbers.)

Complexity Weight Table
Number of inputs	8	Rated complexity	low	3 points
Number of outputs	19	Rated complexity	average	5 points
Number of inquiries	10	Rated complexity	average	5 points
Number of files	35	Rated complexity	high	11 points
Number of interfaces	60	Rated complexity	high	13 points

a. The total function point count is:

b. Calculate the estimated project duration:

c. If 25 people are available for the project, what is the estimated project duration?

d. If the project must be complete in six months, how many people will be needed for the project?

Answer 1

a.

Total function point count = 1334

Element	Count	Low	Average	High	Total
Inputs	8	x 3			24
Outputs	19		x 5		95
Inquiries	10		x 5		50
Files	35			x 11	385
Interfaces	60			x 13	780
				Total	1334

b.

6 points = 1 person-month

So, no. of person-month required = 1334 / 6 = 222.333

Given that 7 people can work on the project, the expected duration = 222.333 / 7 = 32 months

c.

Given that 25 people can work on the project, the expected duration = 222.333 / 25 = 9 months

d.

Person-month = 222.33

Duration in months = 6

So, no. of persons required = 222.33 / 6 = 37
