Almost everything done on an industrial scale will have some standards put in place in order to ensure a consistency throughout the entire industry. The same thing applies to software testing.  software testing standards  being used today were set in place thanks to the efforts of software experts after using scientific testing methods.

These standards used to ultimately ensure no software goes out to the market with any significant amount of bugs contained that may adversely affect computer systems.
