This exploration zeroed in on diminishing oddball level contained in milk would production be able to handle Ø 502 X 603 with Quality Control Circle (QCC) technique. The technique depends on a critical thinking philosophy with the PDCA cycle approach, that is: Plan (maintenance program), Do (execute), (review), Activity (make enhancements). which joins the 7 devices technique just as other cycle enhancement draws near. In light of the outcomes acquired oss bubble, voide/unfilled as the biggest number of rejects is just about as much as 15,200 computers or 38.59% of the absolute oddball.
