My stance, informed by over 7 years of specialized software testing experience across both web and mobile application platforms, is this: I don't wait for engineering to invite me to the table; I demonstrate the value of QA-driven design by embedding practical, risk-prioritized acceptance criteria right into the earliest stages. True shift-left is achieved through strategic empowerment and a proactive cultural intervention, independently of existing organizational silos. It's about leading the quality mindset change, not waiting for permission.
