RAM Quality Assurance & Improvement 2

Question 1

Which statistical tool is used to identify the vital few causes responsible for the majority of quality defects in a RAM program?

Accepted Answer

Pareto chart

Answer

Pareto charts apply the 80/20 rule to rank defect causes by frequency, helping teams focus improvement efforts on the most impactful issues.

Question 2

In the context of RAM quality improvement, what does the term 'corrective action' specifically address?

Accepted Answer

Eliminating the root cause of an existing nonconformance

Answer

Corrective action eliminates the root cause of a detected nonconformance to prevent its recurrence, distinct from preventive action which addresses potential issues.

Question 3

A RAM engineer applies a Six Sigma DMAIC cycle. Which phase involves measuring the current process capability?

Accepted Answer

Measure

Answer

The Measure phase quantifies the current process performance and establishes a baseline for comparing improvements.

Question 4

What quality metric expresses the probability that a system will perform its required function when called upon, accounting for both reliability and maintainability?

Accepted Answer

Availability

Answer

Availability combines reliability (MTBF) and maintainability (MTTR) into A = MTBF / (MTBF + MTTR), reflecting operational readiness.

Question 5

Which approach in quality improvement focuses on eliminating waste and improving flow in production processes most directly applicable to maintainability?

Accepted Answer

Lean methodology

Answer

Lean methodology targets non-value-adding activities (waste), reducing repair cycle times and improving maintainability throughput.
