Case study
To obtain an estimate for its project, a Software House estimates the number of Function Points (FP) for each Information Domain Value as follows.
| Nilai Domain Informasi | Sederhana | Menengah | Kompleks |
|----------------------------|-----------|----------|----------|
| Jumlah Input | 25 | 110 | 190 |
| Jumlah Output | 24 | 120 | 430 |
| Jumlah Inquiry | 85 | 110 | 240 |
| Jumlah File | 77 | 110 | 250 |
| Jumlah Interface Eksternal | 38 | 60 | 70 |From the data above
- Calculate the total CFP (Crude Function Point) value!
- Calculate the value of RCAF (Relative Complexity Adjustment Factory), if the estimated complexity value obtained is as follows.

| 12. | Variasi organisasi pelanggan | 2 |
| 13. | Kemungkinan perubahan fleksibilitas | 2 |
| 14. | Kebutuhan kemudahan penggunaan | 2 |3. Calculate the FP (Function Point) value!
4. If this project uses the Visual Basic programming language, calculate the estimated LOC (Line of Code) obtained!
5. If a programmer can complete 25 LOC in 1 hour, then calculate the effort put into the project!
6. If the average hourly wage is Rp. 20,000, then calculate the estimated total cost of the project!

FP = CFP x (0.65 + 0.01 x RCAF)
FP = 14195 x (0.65 + 0.01 x 39)
FP = 14195 x 1.04
FP = 14762.8

Total cost = number of hours x hourly wage
Total cost = 17715.36 x 20,000,-
Total cost = Rp.354,307,200,-
Netizen Comments
- Q1: ZAKI PRASASTI 20 Jun 2016, 04:20:00 = Where did you get the FP of 0.65 + 0.01 from, bro?
- A1: The numbers 0.65 and 0.01 are constants created by the International Function Point User Group (IFPUG).
- Q2: Where do you get LOC 30 from?
- A2: From the program file, for example, if you create a login page, there are 3 files to build the login page, for example controller, model, view, then just accumulate each line of code in the file.
