ABSTRACT
Many people believe that Error Proofing is defined as an improvement to a process that is designed to prevent defects from occurring. This in reality is the prevention of errors by detection. This may be one or multiple defects that could occur in a process. Error proofing should also foster a technique that is conducive to operator safety, prevents damage to a machine, and of course, prevents defects from being produced or passed on to the next operation or the final customer. Additionally, Error Proofing devices should be simple, low cost, and provide 100% assessment and immediate feedback to an abnormal condition. When I say low cost, I mean you have to weigh the cost of the Error Proofing device against the cost of potential defects made or a recall from the field. A field recall is not only very expensive, but high in cost to customer confidence, and I am not sure you can put a price on that.
