Analyzing relationship between the number of errors in review processes for embedded software development projects

In this study, we examine the relationship between review processes on embedded software development projects. We use the Shapiro-Wilk test and Spearman´s rank correlation coefficient to analyze them. The results indicate that the data selected was not from a normally distributed population. The results of Spearman´s rank correlation coefficient exhibite the following: (1) the number of errors identified in conceptual design review (CDR) has a slightly effect on the number of errors identified in subsequent review processes except for module design review (MDR), (2) the same holds for MDR and programming review (PGR), (3) the number of errors identified in functional design review (FDR) influences the number of errors identified in subsequent review processes except for MDR, (4) the precision of structural design (SD) has an effect on the precision of programming (PG).
