What is the primary purpose of a Gage R&R study in the Measure phase?
Answer: To assess the repeatability and reproducibility of a measurement system
A Gage R&R study evaluates whether a measurement system produces consistent results across different operators and repeated measurements.
Which metric represents the total number of defect opportunities per million in a process?
Answer: DPMO
Defects Per Million Opportunities (DPMO) quantifies the defect rate normalized to one million opportunities, enabling comparison across different processes.
A process has a Cpk of 0.8. What does this indicate?
Answer: The process is not capable of meeting specifications
A Cpk below 1.0 indicates the process is not capable of consistently producing output within specification limits.
What type of data would you collect when recording the number of scratches found on a painted surface?
Answer: Discrete (attribute) data
Counting defects such as scratches produces discrete attribute data because each scratch is a countable, whole-number event.
In a measurement system analysis, what does 'reproducibility' specifically evaluate?
Answer: Variation due to different operators measuring the same part
Reproducibility measures the variation introduced when different operators use the same gage to measure identical parts.
Which tool is used to visually display the frequency distribution of collected process data during the Measure phase?
Answer: Histogram
A histogram displays data in bars representing frequency intervals, making it easy to see the shape, spread, and center of a data distribution.
