CPIM Quality and Continuous Improvement 5

Question 1

What is the purpose of a gauge R&R (Repeatability and Reproducibility) study?

Accepted Answer

Assess whether a measurement system contributes excessive variation relative to the process or specification

Answer

Gauge R&R evaluates how much of total observed variation comes from the measurement system itself (repeatability and reproducibility) versus the actual process.

Question 2

A Cpk value of 1.33 for a process means:

Accepted Answer

The process is centered and producing output well within specification limits

Answer

A Cpk of 1.33 corresponds to a 4-sigma process, which is considered capable and acceptable in most industries.

Question 3

In the PDCA (Plan-Do-Check-Act) cycle, what happens during the 'Check' phase?

Accepted Answer

Evaluate results against the planned objectives

Answer

The Check phase compares actual results from the 'Do' phase against the expected outcomes defined in the 'Plan' phase.

Question 4

Which quality philosophy introduced the concept of 'Zero Defects' and argued that 'quality is free' because prevention costs less than failure?

Accepted Answer

Philip Crosby

Answer

Philip Crosby championed Zero Defects and argued that doing it right the first time eliminates costly rework and failure, making quality free.

Question 5

A manufacturer finds that 80% of customer returns are caused by 3 out of 25 product defect types. What quality principle does this illustrate?

Accepted Answer

Pareto Principle (80/20 rule)

Answer

The Pareto Principle states that roughly 80% of effects come from 20% of causes, helping teams prioritize the vital few issues.
