John, the Production Manager of a food manufacturing plant is having a good day. At least until the Quality Manager bursts into his office: "John, I can't believe that your operators can't put a seal on a jar."
John is surprised and replies, "What are you talking about, Steve? We haven't had to put product on hold for seals for months. I told the team that they better be careful when adjusting the sealer during the change-overs after the last issue."
