Shifting QA left in software testing emphasizes early involvement in the development process to uncover defects when they are cheaper to fix. This approach promotes collaboration among engineering, QA, product, and delivery teams to align on customer value and prevent misunderstandings that lead to critical software failures. The strategy includes making QA a shared responsibility across teams, focusing on prevention rather than detection, and leveraging automation to expedite defect identification. Effective practices, such as unit testing, the use of linters, static code analysis, and static testing, are crucial for enhancing code quality and efficiency. Ultimately, shifting QA left is more about adopting a cultural and mindset change within an organization to improve release quality and reduce costs. The author, Dileep Marway, advocates for this collaborative mindset, drawing on his extensive experience in quality assurance and agile consultancy.
