Which of the following best describes the purpose of a pre-control chart?
Answer: Providing a quick setup check without requiring historical data
Pre-control uses color zones derived from specification limits to verify a process is acceptable at startup without needing baseline statistics.
A gage R&R study reveals that %GRR is 28%. What action is most appropriate?
Answer: Consider the system marginally acceptable; review for critical applications
Industry guidelines classify %GRR of 10–30% as marginally acceptable, requiring judgment based on application criticality and costs.
Which document formally describes the quality-related activities, resources, and responsibilities for a specific product or project?
Answer: Quality plan
A quality plan specifies quality practices, resources, and activities tailored to a particular product, project, or contract.
In the DMAIC problem-solving methodology, the 'Analyze' phase primarily focuses on:
Answer: Identifying and verifying root causes of defects
The Analyze phase uses data and statistical tools to identify and validate the root causes that drive the problem identified in Define/Measure.
What is the primary purpose of a Control Plan in manufacturing?
Answer: Define inspection frequency, methods, and reaction plans for key process characteristics
A Control Plan outlines the process characteristics to monitor, measurement methods, sample sizes, frequencies, and required reactions to out-of-control conditions.
Which acceptance sampling standard is most widely used for attribute inspection by the US military and many industries?
Answer: ANSI/ASQ Z1.4
ANSI/ASQ Z1.4 (formerly MIL-STD-105) is the predominant attribute acceptance sampling standard defining AQL-based single, double, and multiple sampling plans.
When a control chart shows a non-random pattern of seven consecutive points all above the centerline, this is called:
Answer: A run
Seven or more consecutive points on one side of the centerline constitute a 'run,' signaling a likely shift in process mean.
