Reading Tables 1 and 2, a meaningful result can be easily
noticed: using DM in testing a product already tested with
CM, it is immediately evident how not only the old malfunctions

exercised the product using DM were the same as those who
had used CM before. This fact means that DM can be easily
and quickly learned.
