Question
Meena Chavan Corp.'s computer chip production process yields DRAM chips with an average life of 1,800 hours and = 100 hours. The tolerance upper and lower specification limits are 2,400 hours and 1,600 hours, respectively. Based on the given information, the process capability ratio =
For the given information, the process capability index (Cpk) = (round your response to two decimal places).
Based on the process capability index for the given information, one can say that the process ??????? the specification.
Explanation / Answer
Cp = (USL - LSL) / (6 * Standard Deviation) = (2400 - 1600) / (6 * 100) = 800 / 600 =1.33
Yes, this process is capable of producing DRAM chips to specification because when the process Cp is greater than or equal to 1.0, the process has potential of being capable.
