Determine Optimum Module Size for Software Inspections


    Setup cost for an inspection in person-hrs (a1) :

    


Person hour increase in inspection cost per LOC (a2) :

(i.e. inspection cost is a1+a2*size)                  

    

   Average cost of fixing a defect in later phases       :
Average cost of fixing a defect in the present phase   

    

                Average cost of false alarm                   :
Average cost of fixing a defect in present phase   

    


The parameter k for the control limits :

(limits are set at k*sigma around the mean)

    

Number of KLOC before process goes out of control (d) :
