The purpose of CAPAs is to ensure that the product is up to the highest consumer standards. The preventative actions are required to foresee every possible negative outcome. These preventative actions are used to anticipate what can go wrong and try to fix it before the device reaches the market. Since it is impossible to foresee everything, corrective actions are in place to fix issues once it has already been on the market and must be fixed. These CAPAs are put in place to create the safest and most effective medical devices and refine based on those already released.
