Lean Six Sigma Yellow Belt Certification Assessment 2

Question 1

In Lean Six Sigma, what does a Process Capability Index (Cpk) value of 1.33 indicate?

Accepted Answer

The process is capable and meeting specifications with margin

Answer

A Cpk of 1.33 means the process is producing output well within specification limits, reflecting a capable and stable process.

Question 2

Which assessment tool is used to visually map all steps in a process and identify value-added versus non-value-added activities?

Accepted Answer

Value Stream Map

Answer

A Value Stream Map (VSM) visually depicts the flow of materials and information and distinguishes value-added from non-value-added steps.

Question 3

A Yellow Belt team is assessing a process and finds a sigma level of 2. What does this mean?

Accepted Answer

The process produces about 308,537 DPMO

Answer

A sigma level of 2 corresponds to approximately 308,537 defects per million opportunities, indicating a poorly performing process.

Question 4

What is the purpose of a Gage R&R study in a Lean Six Sigma assessment?

Accepted Answer

To evaluate measurement system variation due to repeatability and reproducibility

Answer

Gage R&R (Repeatability and Reproducibility) assesses whether a measurement system contributes excessive variation that could mask true process performance.

Question 5

During process assessment, a team calculates a Rolled Throughput Yield (RTY) of 0.72. What does this indicate?

Accepted Answer

72% of units pass through all process steps defect-free

Answer

RTY of 0.72 means only 72% of units complete all process steps without any defect or rework, revealing hidden factory losses.
