Video Excel Online Activity: Taguchi Cassette tapes are still used in some handheld recording devices and in less expensive portable musical instrument recording devices. The desired speed of a cassette tape is 1.875 inches per second. Any deviation from this value causes a change in pitch and tempo and thus poor sound quality. Suppose that adjusting the tape speed under warranty when a customer complains and returns a device costs a manufacturer $25. Based on past information, the company knows the average customer will return a device if the tape speed is off the target by at least 0.200 inch per second; in other words, when the speed is either 2.075 or 1.675. Suppose that a technician tests the tape speed prior to packaging and can adjust the speed to the target of 1.875 at a cost of $3. What should the economic specification limits be?
