Lean Six Sigma Yellow Belt Certification Measure Phase Tools 3

Question 1

In a Gage R&R study, a high percentage of variation attributed to 'Part-to-Part' variation is:

Accepted Answer

Desirable because it shows the measurement system can distinguish between parts

Answer

High part-to-part variation relative to gauge variation means the measurement system is sensitive enough to detect real differences between parts.

Question 2

A SIPOC diagram is primarily used during the Measure phase to:

Accepted Answer

Provide a high-level view of the process and its key inputs and outputs

Answer

SIPOC maps Suppliers, Inputs, Process, Outputs, and Customers at a macro level to scope the process being measured.

Question 3

Which control chart is most appropriate for monitoring the proportion of defective units in a process with variable subgroup sizes?

Accepted Answer

p-chart

Answer

The p-chart is designed for attribute data tracking the proportion defective and accommodates varying subgroup sizes.

Question 4

What is the primary purpose of establishing operational definitions before data collection?

Accepted Answer

To ensure everyone collects and interprets data consistently

Answer

Operational definitions eliminate ambiguity so all collectors measure the same characteristic in the same way, ensuring data integrity.

Question 5

In the context of Lean Six Sigma, 'Takt time' is calculated as:

Accepted Answer

Available production time divided by customer demand rate

Answer

Takt time sets the pace of production by dividing available work time by the rate of customer demand.
