Learn how SPC has helped others in the chemical industry"Since color wasn't a typical specification for that particular ingredient, our normal testing protocols didn't catch it. But thanks to the ease with which we were able to produce control charts and overlay them with the delivery schedules, we were able to pinpoint the problem and get back on track. It was very powerful information." -Quality Assurance Supervisor at chemical plant "There's no way for an operator to know how much the viscosity is varying. We deal with it by running control charts, looking at the data trend, and when the data lines up in a row above or below the center line on the control chart, we know there's something consistently wrong with the flow rate and can adjust the throughput." -Advising Engineer at refinery |
