Skilled software testing has not fit well into the culture of Agile development. Agile was not created by testers, or with testers, or with deep testing in mind. As a result, people who study and practice the testing discipline have done so largely outside of Agile culture. To help fix this, Michael Bolton and I have created a new version of the "Agile Testing Quadrants" that helps us explain a better way for testing and development to coexist.
