Accordingly, the transition from one error in 500 lines to one error on the 2000 lines and above is performed by software testers. The average American program has an error every 2,100 lines of code.

As the statistics show conduct of functional testing by an independent test agency reduces the number of software bugs from 3 to 30 times.
