TESTING USUALLY TAKES PLACE VERY LATE Typical QA tests must wait until there is some working application so that the tests can be “recorded” and then played back later. But if you have to wait, you’re already slowing down your delivery
YOU’RE PROBABLY TRYING TO FIX IT WITH TESTING Testing in all its forms seldom tops 85% in total defect removal efficiency. A combination of pretest removal and testing removal is necessary to top 95%... As it happens, 95% is a good demarcation line between good quality and mediocre quality. a National Research Council study on “dependable software” concluded that testing is no longer sufficient to ensure an application will be reliable, efficient, secure, and maintainable. When all sources and kinds of software defects are considered as a set, coding defects only comprise about 17% of the total defect volume.
