Lean Six Sigma Yellow Belt Certification The Analyze Phase 5

Question 1

In FMEA (Failure Mode and Effects Analysis), what does the Risk Priority Number (RPN) represent?

Accepted Answer

The product of Severity, Occurrence, and Detection ratings

Answer

RPN = Severity × Occurrence × Detection; it prioritizes failure modes so teams focus improvement efforts on the highest-risk issues first.

Question 2

Which of the following best describes a 'process map' used during the Analyze phase?

Accepted Answer

A visual representation of the steps, inputs, and outputs of a process

Answer

A process map (flowchart or value stream map) visually depicts each step in a process along with inputs, outputs, and decision points to identify inefficiencies.

Question 3

A team calculates that their process produces 3.4 DPMO. What sigma level does this correspond to?

Accepted Answer

6 sigma

Answer

3.4 defects per million opportunities corresponds to a Six Sigma level of performance, accounting for a 1.5-sigma shift in the mean.

Question 4

What type of variable is 'number of customer complaints per day'?

Accepted Answer

Discrete (attribute) variable

Answer

Count data like complaints per day are discrete (attribute) variables because they can only take whole-number values and cannot be subdivided meaningfully.

Question 5

Which lean concept refers to producing only what is needed, when it is needed, and in the amount needed?

Accepted Answer

Just-In-Time (JIT)

Answer

Just-In-Time (JIT) production pulls work through the system based on actual demand, eliminating overproduction and excess inventory waste.
