Which Lean waste refers to producing more than what is needed by the next process step?
Answer: Overproduction
Overproduction means making more, earlier, or faster than required by the next process, and is often considered the worst form of waste.
A process with a Cpk of 0.8 indicates what about process capability?
Answer: The process is not capable
A Cpk below 1.0 means the process is not capable of consistently meeting specification limits and requires improvement.
What is the main difference between a control chart and a run chart?
Answer: Control charts include statistically calculated control limits
Control charts add upper and lower control limits calculated from process data, enabling detection of special cause variation beyond simple trend observation.
In a Pareto analysis, the 80/20 rule suggests that approximately what percentage of problems come from a vital few causes?
Answer: 80%
The Pareto principle states that roughly 80% of effects come from 20% of causes, helping teams prioritize the most impactful issues.
Which tool is used in the Improve phase to systematically test factor combinations and their effects on output?
Answer: Design of Experiments
Design of Experiments (DOE) systematically varies multiple factors simultaneously to determine their individual and combined effects on process output.
What is the purpose of a measurement system analysis (MSA) in Six Sigma?
Answer: To evaluate the reliability and accuracy of a measurement system
MSA evaluates whether a measurement system produces consistent and accurate results, ensuring collected data is trustworthy for analysis.
