Measure (GB2) by Vishwadeep Khatri | Nov 2, 2018 | 0 comments 1. The design specification for a cap diameter is 2 ± 0.05 cm. The diameter data follows normal distribution with mean of 2.02 cm and standard deviation of 0.01 cm. Calculate Cp, Cpk and give appropriate recommendation Cp=1.67, Cpk=1; Process mean to be shifted to target Cp=0.33, Cpk=0.2; Process mean to be shifted to target Cp=0.33, Cpk=0.33; Variation to be reduced Cp=1.67, Cpk=1; Variation to be reduced2. The purpose of operational definition is to provide a single, agreed upon meaning of the CTQ to all the stakeholders to ensure reliability and consistency of measurement to provide a clear and understandable description of what is to be observed and measured All the above3. 100 transactions were inspected, 20 errors were found in 15 transactions. What is DPU? 0.02 2 1.33 0.24. Which of the following statements is FALSE? Sigma level can be calculated for both discrete and continuous data If standard deviation decreases, Sigma level increases Sigma level can be converted to a corresponding DPMO All processes should operate at a six sigma level5. Quality team at an online retailer checks images and classifies them as “OK” or “NOT OK”. Although 70% of the images are handled by automation, 30% images are still checked manually which the system fails to classify correctly. Which of the following is an appropriate method to validate the manual measurement system? Focus on the operational definition Logical validation Gage Repeatability and Reproducibility Attribute Agreement Analysis6. All the statements given below are false, EXCEPT Cpk is always equal to or greater than Cp If the Cpk value becomes zero, then the process average is at one of the specification limits The Cp and Cpk values will be 2 if the process is perfectly centered In both Cp and Cpk, the lower the value, higher the performance level7. During frisking at airports, the metal detectors are passed over the metal belt first. This is an example of: Logical validation Repeatability Attribute agreement analysis Gage R & R8. An appraiser provides consistent scores every time he makes a measurement. All other appraisers show similar performance. However many of them do not agree with the standard answer. The issue is with the: Appraiser Repeatability Appraiser Accuracy Appraiser Reproducibility Team repeatability9. As per the SLA, all complaints should be resolved within 8 hours. Currently the average resolution time is 4.57 hours and standard deviation is 0.8 hours. What is DPMO? 4.29 9.0 5.97 None of the above10. DPMO can be calculated from: Continuous data following normal distribution, provided specifications are known Defects data provided OFE is known Defective data All the above11. The FTY’s of four sequential process steps are 0.8, 0.91, 0.90, 0.99. What is the RTY and Zst respectively? RTY = 0.6486; Zst = 0.38 RTY = 0.99; Zst = 3.83 RTY = 0.6486; Zst = 1.88 RTY = 0.7920; Zst = 2.3112. Which of the following process has the highest Capability Index (Cp)?Process A - USL = 30, LSL = 20, Mean = 20, Standard Deviation = 1Process B - USL = 30, LSL = 20, Mean = 15, Standard Deviation = 2Process C - USL = 31, LSL = 21, Mean = 25, Standard Deviation = 1 Process A Process B Process C Both Process A and C13. “Higher the better” applies to all the following, EXCEPT Sigma level Cp DPU YieldTime is Up!
