What is the primary purpose of a 'pre-control chart' in manufacturing?
Answer: Quickly set up a process and monitor early production
Pre-control charts are used during setup and early production to quickly confirm the process is centered before switching to SPC charts.
During a quality audit, an auditor finds that a corrective action was implemented but the problem recurred. What does this most likely indicate?
Answer: The root cause was not properly identified or addressed
Recurrence after a corrective action typically means the true root cause was not found or the fix did not address the actual source of the problem.
What is the difference between 'accuracy' and 'precision' in measurement?
Answer: Accuracy is closeness to true value; precision is repeatability/consistency
Accuracy describes how close a measurement is to the true value, while precision describes how consistently repeated measurements agree with each other.
What does 'first pass yield' (FPY) measure?
Answer: The percentage of units completing a process without any defects or rework
FPY measures the fraction of units that go through the entire process correctly the first time, without needing rework or repair.
Which measurement device uses an anvil and spindle to measure the thickness of flat stock?
Answer: Outside micrometer
An outside micrometer uses a precision-threaded spindle and anvil to measure external dimensions such as the thickness of flat stock.
In quality management, what is meant by 'zero defects'?
Answer: A performance standard of doing work right the first time
Zero defects is a quality philosophy and performance standard meaning every task is completed correctly the first time, every time.
A torque wrench is used in final assembly and requires calibration. Who is responsible for ensuring it is calibrated before use?
Answer: The operator and the quality/maintenance system
Both the operator (to verify calibration status before use) and the quality/maintenance system (to schedule and perform calibration) share responsibility.
