In Lean Six Sigma, what does a Process Capability Index (Cpk) value of 1.33 indicate?
Answer: The process is capable and meeting specifications with margin
A Cpk of 1.33 means the process is producing output well within specification limits, reflecting a capable and stable process.
Which assessment tool is used to visually map all steps in a process and identify value-added versus non-value-added activities?
Answer: Value Stream Map
A Value Stream Map (VSM) visually depicts the flow of materials and information and distinguishes value-added from non-value-added steps.
A Yellow Belt team is assessing a process and finds a sigma level of 2. What does this mean?
Answer: The process produces about 308,537 DPMO
A sigma level of 2 corresponds to approximately 308,537 defects per million opportunities, indicating a poorly performing process.
What is the purpose of a Gage R&R study in a Lean Six Sigma assessment?
Answer: To evaluate measurement system variation due to repeatability and reproducibility
Gage R&R (Repeatability and Reproducibility) assesses whether a measurement system contributes excessive variation that could mask true process performance.
During process assessment, a team calculates a Rolled Throughput Yield (RTY) of 0.72. What does this indicate?
Answer: 72% of units pass through all process steps defect-free
RTY of 0.72 means only 72% of units complete all process steps without any defect or rework, revealing hidden factory losses.
Which of the following best describes 'baseline data' in the context of a Six Sigma assessment?
Answer: Pre-improvement data used to quantify current process performance
Baseline data captures current performance before any changes so the team can measure the actual impact of improvements.
A team assessing cycle time finds that the average is 10 minutes but the takt time is 8 minutes. What does this imply?
Answer: The process cannot keep up with customer demand
When cycle time exceeds takt time, the process produces too slowly to meet customer demand, signaling a bottleneck.
