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.
