A pharmaceutical company is validating a new titration process. A Gage R&R study was performed on the measurement system used to determine chemical concentration. The results show a %Contribution from Part-to-Part variation of 65%, Repeatability of 30%, and Reproducibility of 5%. The Number of Distinct Categories is 4. What is the most appropriate next step for the quality team?
Q2
A project team is using a full factorial Design of Experiments (DOE) to optimize the tensile strength of a polymer. After running the experiment, the analysis reveals a strong, statistically significant interaction between Temperature and Curing Time. How should this interaction be interpreted for process optimization?
Q3
A call center wants to determine if a new scripting software reduces the average handle time (AHT) of customer calls. A pilot study is conducted with 25 agents using the new software and 25 agents using the old script. The data for both groups is found to be non-normally distributed. Which statistical test is most appropriate to compare the median AHT between the two groups?
Q4Multiple answers
A project charter has been drafted for an initiative to reduce shipping errors in a distribution center. The 'Goal Statement' reads: 'Significantly improve the accuracy of shipments and enhance customer satisfaction.' Why is this statement inadequate for a Six Sigma project? (Select TWO)
Q5
True or False: In a Control Plan, the Response Plan section should only detail the steps for the process operator to take when an out-of-control condition is detected.
Q6
A hospital is experiencing delays in its patient discharge process, leading to bed shortages and patient dissatisfaction. The process involves physicians, nurses, pharmacists, and administrative staff. The project team needs to understand the flow of activities, handoffs, and decision points to identify bottlenecks. The current process starts when a physician writes a discharge order. This triggers parallel activities: the nurse provides final patient instructions, and the pharmacy prepares take-home medications. Once both are complete, an administrator finalizes billing and paperwork. However, delays are common. Nurses are often busy with other patients, and the pharmacy can be backlogged. Sometimes, the final paperwork reveals insurance issues, sending the process back to the administrative stage and causing significant rework. The hospital administration wants a solution that reduces the average discharge time by 30% within six months. The solution must not compromise patient safety or the accuracy of billing. The project team has collected preliminary data showing that the 'pharmacy preparation' and 'final paperwork' steps have the highest variability in completion time. Which tool should the team use FIRST in the Measure phase to visually document the entire process, including all roles, handoffs, and decision points?
Q7
The R-squared value from a simple linear regression analysis is 0.85. What does this value indicate?
Q8
A manufacturing team is implementing a 5S program. They have successfully completed the first three steps: Sort, Set in Order, and Shine. What is the primary objective of the fourth step, Standardize?
Q9
During a process capability analysis for a normally distributed process, a Black Belt calculates Cp = 1.67 and Cpk = 0.95. What can be concluded about this process? ```mermaid graph LR A[Specification] --> B(Process Distribution) subgraph B direction LR C(LSL) -- 1.67 σ --> D(USL) E(Process Mean) -.-> F{Off Center} end style C fill:#f9f,stroke:#333,stroke-width:2px style D fill:#f9f,stroke:#333,stroke-width:2px style E fill:#ccf,stroke:#333,stroke-width:2px ```
Q10
A team is conducting a Failure Modes and Effects Analysis (FMEA) on a new medical device assembly process. They have identified a potential failure mode, calculated the Severity, Occurrence, and Detection ratings, and computed the Risk Priority Number (RPN). What should the team do immediately after calculating the RPNs for all identified failure modes?
