“Standard method for measuring the development of software from the user's point of view.
Count the number of different features
Features in this step are the same that function points define, adding the count of the algorithms. This is:
Calculate features’ cost
Each feature has an unique complexity value.
Cost estimation of that features is calculated by multiplying complexity by the count of that feature.
Final estimation are done by applying this equation:
FPE = TOTAL_COUNT * (0.65 + 0.01 * SUM(Fi))
Fi => Result of question number i on information system survey, also defined on function points estimation.
Measures the size of a software project counting the number of lines of code.

E = (a + 4m + b) / 6
a= ideal number of LOC
b= pessimistic number of LOC
m= most probable number of LOC
