According to a study commissioned by the National Institute of Standards and Technology in 2002, software bugs cost the U.S. economy an estimated $59.5 billion annually, or about 0.6 percent of the nation's gross domestic product (GDP). The same study also found that more than one-third of these costs, or an estimated $22.2 billion, could be eliminated by an improved testing infrastructure. These numbers would be significantly higher if the study were conducted today.
