3.1 Project Costing
Function-oriented software matrices use a measure of the functionality
delivered by the application as a normalization value. Since “Functionality cannot be
measures directly,it must be derived indirectly using other direct measures”. Albrecht, who
suggested a measure called the function point, first proposed function-oriented metrics.
Function point are derived using an empirical relationship based on countable (direct)
measure of software’s information domain and assessment of software complexity.
We have chosen Function Point Analysis for our Project Cost Estimation.

6 Does the system require online data entry? 0
7 Does the online data entry require the input transaction to be 0
built over operations?
8 Are the files updated online? 0
9 Are the inputs, output, files or inquiries complex? 2
10 Is the internal processing complex? 3
11 Is the code designed to be reusable? 4
12 Are conversion / installation included in the design? 2
13 Is the system designed for multiple installations in different 4
organizations?
14 Is the application designed to facilitate change? 5
Value Adjusted Factors (Fi) 35
Calculation of Function Point (FP):
𝐅𝐏𝐞𝐬𝐭𝐢𝐦𝐚𝐭𝐞𝐝 = Count Total * (0.65 + 0.01 * (Fi))
= 136* (0.65 + 0.01 * 35)
= 136* 1
=136
Final Function Point Calculation is:
Final Adjusted FP = UFC*VAF
=136*136
=18,496
Cost per Function Point:
Labor Rate =Rs. 42,000
Cost per FP =Labor Rate / Productivity parameter
= 42,000 / 10
= 4200
Total Project cost:
Total Project Cost = FPestimated * Cost Per FP

= 18,496*4200
= 77,683,200
Total Estimated Effort:
Total Estimated Effort = FP est. / productivity parameter
= 136 / 10
= 13.6
Duration of Project
Duration of Project = Effort month / No. of persons
Duration of Project = 13.6 / 2
Duration of Project = 6.8 months.
