32. Computing Function Points: Analyze information domain of the application and develop counts Weight each count by assessing complexity Assess influence of global factors that affect the application Compute function points Establish count for input domain and system interfaces Assign level of complexity or weight to each count Grade significance of external factors, F i such as reuse, concurrency, OS, ... function points = (count x weight) x C where: complexity multiplier: C = (0.65 + 0.01 x N) degree of influence: N = F i
