In a Gage R&R study, a high percentage of variation attributed to 'Part-to-Part' variation is:
Answer: Desirable because it shows the measurement system can distinguish between parts
High part-to-part variation relative to gauge variation means the measurement system is sensitive enough to detect real differences between parts.
A SIPOC diagram is primarily used during the Measure phase to:
Answer: Provide a high-level view of the process and its key inputs and outputs
SIPOC maps Suppliers, Inputs, Process, Outputs, and Customers at a macro level to scope the process being measured.
Which control chart is most appropriate for monitoring the proportion of defective units in a process with variable subgroup sizes?
Answer: p-chart
The p-chart is designed for attribute data tracking the proportion defective and accommodates varying subgroup sizes.
What is the primary purpose of establishing operational definitions before data collection?
Answer: To ensure everyone collects and interprets data consistently
Operational definitions eliminate ambiguity so all collectors measure the same characteristic in the same way, ensuring data integrity.
In the context of Lean Six Sigma, 'Takt time' is calculated as:
Answer: Available production time divided by customer demand rate
Takt time sets the pace of production by dividing available work time by the rate of customer demand.
A scatter diagram showing a strong positive correlation between two variables means:
Answer: As one variable increases, the other tends to increase as well
A positive correlation means the two variables move in the same direction, though correlation alone does not imply causation.
Which tool is used to visually separate the 'vital few' causes from the 'trivial many' in defect analysis?
Answer: Pareto chart
A Pareto chart ranks defects or causes by frequency or impact, highlighting the few categories responsible for most of the problem.
