Two new metrics were calculate in order to further analyze the data.
Firstly,time in design phase per one thousand added and modified codes (Time Design/KLOC)
designated the ratio of all time used in the designing phase based on amount of source code created in the program.
Secondly,overall defects per one thousand added and modified code (Defects/KLOC)
displayed information of defect destiny.
ANOVA were used for comparing and finding significance between means of these two groups of data.
The significance is set at a= 0.05 Figure 4 display the value of both new metrics
