Your company just landed an order to produce ball bearings for the latest Bazinga fidget spinner. A process capability study was conducted on a sample of 100 balls produced on a new grinding machine. The estimated average diameter is 2.016, and the estimated standard deviation is 0.020. The measurements appear to be normally distributed.  The target dimension is 2 mm, with LSL = 1.9 mm and USL = 2.1 mm. Estimate Cpk. Does this process meet Motorola’s Six Sigma quality level? Explain your answer.

Your project team identified several potentially significant factors that could influence weld quality of your company’s #1 selling garden statute, a weldebeest (sic). You have a budget of $10,000 for experiments, which includes materials, testing, and time on the welding machine. Which tool should the team use next in order to understand the cause & effect relationship between the potentially significant factors and weld quality? [tool]

QID [d]. A Six Sigma project team is using a failure mode and effects analysis (FMEA) to analyze issues that could arise with proposed process improvements.  The following ratings were developed for the failure mode that workers did not follow instructions. Detection = [n] Occurrence = [r] Repeatability = [p] Severity = [v] What is the risk priority number (RPN) for this failure mode?

Refer to instructions above on how to “Show Your Work.” Type your solution in the answer box and be sure to answer all parts of the question. In order to provide additional capacity for a top-selling product, a project team is installing a new CNC machine. Before establishing the process performance baseline, the team conducts a gauge R&R study with three operators. Each operator measures the same ten parts, three times each. The target for the dimension is 500, with USL = 560 and LSL = 440.  The ANOVA gave the following estimates: σRPT = 2 σRPD = 6 σPART = 7.75 σTOTAL = 10   Estimate σMS. Estimate % R&R. Based on % R&R, is this measurement system acceptable for use? Explain your decision.

The waste related to diagnostic tests is an opportunity for hospitals to decrease costs. The manager of a trauma unit at one hospital just launched a Six Sigma project aimed at reducing redundant diagnostic tests, with an expected cost reduction of 10%. Which tool could the team use to gain agreement with stakeholders on project scope?  [which]

Refer to instructions above on how to “Show Your Work.” Type your solution in the answer box and be sure to answer all parts of the question. A process capability study was conducted on a sample of 100 parts produced on a new CNC milling machine. For one critical dimension, the sample average was 98.4 and the sample standard deviation was 0.46. The measurements appear to be normally distributed. The target dimension is 95 with LSL = 90 and USL = 100. Estimate Cpk. Does this process meet Motorola’s Six Sigma quality level? Explain your answer.

Measurement system “precision” is best defined by which of the following? [which]

A manufacturer of cell phone covers is experiencing too many visual defects with the ASU Sparky cover for Samsung Galaxy S24 phones. The production team suspects that the visual defects can be isolated to the flame polishing process. The team needs to baseline the current process before making any changes. Which measure(s) should be used to assess process capability? [which]
