Question 1Alberchets approach for effort estimation is primarily based on the notion of function points.
Measuring the functionality in a system as described by the specification. This approach proposes
function points as a technology independent measurement of size. Given by the formula: FP = UFC X
TCF
• Where UFC is unadjusted function point count, TCF is a technical complexity factor . Identifying the
sub functions from the given case study helps to calculate the unadjusted function point. The
unadjusted function point count is the first step in calculating the overall function point. It is
important to take into consideration that the unadjusted function point is an average calculation
without taking into account the environment that it was deployed in.

, Continuation of Question 1
Associate weightings of each sub function
External Inputs (3x4)
Total of 3 external inputs all with a weighting of average – therefore this is equal to 3X4
3x4= 12
External Outputs
There are two external outputs with average weighting = 5
2x5=10
External Inquires
There are two external enquiries with a weighting of 4
2x4=8
External files
There is one external file with an average weighting = 10
1x10= 10
Internal Files
There is one internal file with a complex weighting
1x10= 10
Total =10+10+10+8+12= 50
The total value here is 50 therefore the unadjusted function point is 50 which is beneficial in
calculating the overall function point and the technical complexity factor
