Which of the following is an example of a 'leading indicator' used in Lean Six Sigma process assessment?
Answer: In-process temperature readings monitored in real time
Leading indicators are real-time or predictive measures that allow teams to take corrective action before defects reach the customer.
A team measures the same part five times with the same operator and gets five different readings. This variation is called:
Answer: Repeatability
Repeatability refers to the variation seen when one operator measures the same part multiple times with the same instrument.
What does a run chart primarily help assess in a process?
Answer: Trends, shifts, or patterns in process data over time
A run chart plots data in time sequence to reveal trends, cycles, or shifts that indicate process changes over time.
In a waste assessment, which of the following best represents the waste of 'waiting'?
Answer: An operator standing idle while a machine completes its cycle
Waiting waste occurs when people, materials, or equipment are idle between process steps, adding time without adding value.
A Yellow Belt is assessing data normality before applying certain statistical tools. Which tool is commonly used for this?
Answer: Probability plot (e.g., normal probability plot)
A normal probability plot or Anderson-Darling test checks whether data follows a normal distribution, which is required for many statistical analyses.
When conducting a time study as part of process assessment, what is the team trying to quantify?
Answer: The actual time required to complete each process step
A time study measures how long each process step actually takes, providing data for cycle time analysis and identifying bottlenecks.
Which of the following describes 'Cost of Poor Quality' (COPQ) in a process assessment?
Answer: The total costs incurred due to defects, rework, scrap, and failures
COPQ includes internal failure costs (scrap, rework) and external failure costs (warranty, returns, customer complaints) resulting from poor quality.
