Quantitative Relations Between Transfer Processes

Question: Discuss the quantitative relations between transfer processes. Answer: 1. What is DPMO a. Defects per million opportunities is the full form of DPMO. It measures the performance of the process. The quality of highly capable process is measured using this method. It measures the opportunity of defects in per million situation. It is a measurement of the quality ensuring process of operation popularly known as six sigma. The table of six-sigma provides the value of DPMO. For level of sigma becomes six, the count of DPMO becomes 3.4 (Voehl, 2014). b. Six sigma Number of defects = 50 out of 2500 DPU = 50/2500 = .02 Here opportunity of defect is 1 in every product and the total sample size is 2500. The defect has been counted to 50 in that sample. The required defect in per million opportunity is as follows: DPMO = 20000 From the six sigma table: The 2.5 sigma can be attained by attaining DPMO of 308770 while value of DPMO at 158687 provides the 2.5 sigma of the production (Voehl, 2014). Therefore, in the present scenario, the level of sigma has attained by the concerned production is 2 sigma and just 42000 short of attaining 2.5 sigma. C. Before the shift of mean, the capability index of the process was 0.75. The Limit of specification was high enough for meeting the design specifications. However, the change in the mean of the design process lowering the value of the mean may provide the design a higher Cp but the Cpk cannot be good. The low value of capacity index due to shift of mean may reduce the quality satisfaction of the design for the customers (Wilbanks, 2012). 2. The value of capacity index in the case of dog food, we have found that both the upper and lower level of allowable capacity index are same. The value is too low for maintaining the quality of the products. The measurement also provides that the customers of dog chow may not be happy with this level of amount provided with each bag of Dog Chow. References Voehl, F.
