Hi Tracy / Michael / Wanneng Team Please update the CAP /action plan of each item .For the latest update , I cannot connect the evidence to the concern about confirmation of correct formula ?ExampleYou are mixing the PVC according to your formula , assuming all mixing is correct and followed as per your internal spec . So after mixing , how do you know if it is really a correct mixing or follow the right formula ? There are other 6 items need to provide CAP – please help follow up Thanks
