Integrating UX QA into your development process is best done through an agile or iterative approach, where you test and improve your product continuously and incrementally, based on user feedback and data. To do this, you should first define your UX goals, objectives, and requirements, as well as your UX testing strategy, methods, and metrics. Then, create your UX design, such as wireframes, prototypes, or mockups, and test them with users or experts. After that, implement your UX design into your product and test them for functionality and accessibility. Then, launch your product to a subset or the whole of your target audience and test them for usability and performance. Finally, analyze your UX testing results and feedback and identify any areas for improvement or optimization, and repeat the cycle until you achieve your desired UX outcomes.
