ESTIMATING SOFTWARE COSTS WITH FUNCTION POINTS Suppose you were required to create a reasonably detailed estimate for developing a new student information and admissions system at a local college. Your firm’s programmers average 6 function points on a person-month basis. After speaking with representatives from the college, you know that their request is based on the following screen requirements: inputs (4), outputs (7), interfaces

(12), queries (20), and files (16). Further, we have determined that the relative complexity of each of these functions is as follows:

inputs (low), outputs (medium), interfaces (high), queries (medium), and files (medium). Using this information and the following table, calculate the number of function points for this project.

Complexity Weighting Medium Function Low Number of Inputs 3 x 6 x 9 Number of Outputs 2 x 6 x 10 X Number of Interfaces 1 x 3 x 5 x Number of Queries 4 x = 8 12 X Number of Files 4 = 6 x 8 High Total
