The Ed Kit Principle

When I took a practice test for ISTQB certification I came across the question asking 'The quality and effectiveness of software testing are primarily determined by the quality of the test processes used is stated in' a) Bill Hetzel Principle b) Ed Kit principle c) IEEE 829 d) IEEE 8295 The correct answer was the Ed Kit Principle, and since I didn't know what that was I decided to do some research. Basically the Ed Kit principle states that "The quality and effectiveness of software testing are primarily determined by the quality of the test processes used.".  So in other words the way that a tester's testing methods are determines how good the tests they run are. Like the Bill Hetzel Principle the Ed Kit Principle isn't really mentioned by name in the ISTQB software testing book despite it appearing once in a while on online practice tests.  However that doesn't mean it isn't present in the book, and in fact has a significant presence.  If you have a copy of the book the principle is referenced a lot in at least in section 1.4 Fundamental Test Process.  Just remember if you're looking for the principle by name you will not be able to find it, just remember that the principle is about how quality of the test processes determine the quality of the tests.
