Analyzing root causes

#2. What is the purpose of sampling in data collection?

To analyze all possible data points

To estimate process characteristics using a subset of data

To eliminate process variation

To standardize the data collection process

#3. Which of the following describes DPMO?

The total number of opportunities for improvement

The number of defects per million opportunities

The number of process steps in a workflow

The number of variations in process capability

#4. What is the purpose of data collection in the Measure phase?

To create process maps

To evaluate team performance

To gather information for process analysis

To monitor improvements

#5. What does DPMO stand for in Six Sigma?

Defects Per Measurement Opportunity

Defects Per Million Opportunities

Defects Per Manufacturing Operation

Defects Per Market Observation

#6. What is the significance of a low Cp value?

The process has minimal defects

The process is highly capable

The process does not meet specification limits

The process is well-centered

#7. What is the main output of the Measure phase?

Validated solutions

A root cause analysis

Baseline performance metrics

A project charter

#8. Which type of data includes categories like ‘pass’ or ‘fail’?

Continuous data

Variable data

Attribute data

Interval data

#9. Which of the following describes Cpk?

The process mean

The potential of a process to produce within specification limits

The actual capability of a process considering mean variation

The number of defects per million opportunities

#10. What is the purpose of control limits in process capability?

To determine specification limits

#12. What is the difference between Cp and Cpk?

Cp accounts for process centering, while Cpk does not

Cp measures potential capability, while Cpk considers mean variation

Cpk measures defects, while Cp measures variation

Cp measures defects per million opportunities, while Cpk measures capability

The number of defects in a process

The efficiency of process flow

#16. Which of the following is NOT a key metric in the Measure phase?

DPMO

Sigma level

Cp and Cpk

Kaizen index

#17. What does a higher Sigma level indicate?

More defects

Fewer defects

More process variation
