1. Own QA
Ensure at least one person has overall responsibility os the QA process. Even if you outsource every other function of your QA, you need someone internal to own your testing stategy.
2. Integrate more
Involve your QA team in the development process quicker so you can iterate and adjust faster. Include tasters in multiple stages of the SDLC to get the feedback loop happening faster.
3. Prioritise
Make QA a priority in your company, not just a way of highlighting what is broken. Try to think how QA can be a revenue generating team as opposed to a cost centre.
