Product Cost Factor DATA

The DATA cost driver delineated in the following table captures the influence test data requirements have on program development. Its rating is assessed by calculating the ratio of bytes in the testing database to SLOC in the program. The basis for this cost driver is that database size is important for the reason that of the resources required for generating test data.

DATA Descriptors   Testing DB bytes/Pgm SLOC < 10 10 = D/P < 100 100 = D/P < 1000 D/P = 1000  
Rating Levels Very Low Low Nominal High Very High Extra High
