The author, Ashley Hunsberger, a Quality Architect at Blackboard, Inc., is writing an open letter to developers to address the common misconception that QA is their enemy. She emphasizes that quality is a team effort and not just owned by testers. The author criticizes "The Hotshot" developer type who thinks only testers own quality and fails to write unit tests or integrate tests for their code, sending buggy code to QA. Ashley encourages developers to take ownership of quality, work with QA to define tests upfront, and run their own tests before submitting code. She also stresses the importance of testing culture and collaboration between teams. The author invites developers to join her in creating a better team dynamic and working together to achieve quality and Continuous Delivery.
