Webinar: Swap Tests

One of the challenges in manufacturing is when a product defect occurs intermittently and its source is unknown. The defect could be from a given process, or from one of the machines or operators within a process step. There could also be more sources. The natural inclination is to create a designed experiment to determine the source of the defect. However, this can be impractical for several reasons, mainly because of the intermittent aspect of the defect.

For batch processing the experimental design technique "Swap Tests" can be used to successfully design experiments to isolate the problem area creating the defect. It can be employed for any number of processes and is only limited by a minimum batch size required based upon the design. As an added benefit, it does not shut down operations in order to conduct the testing.
