OVERVIEW Why Do Six Sigma?
Note: While this quiz corresponds to the online course, it is not functional in this demo version.
Question 1
A six sigma level of quality:
- implies 99.73% of the output will meet customer requirement.
- equates to a Capability Index of 1.33.
- represents 3.4 defects per million opportunities.
- provides half the defects of a 3 Sigma level of quality.
Question 2
As an organization's Sigma Level increases:
- the Cost of Quality increases.
- the Cost of Quality decreases.
- the Cost of Quality is not affected.
- None of the above.
Question 3
A criticism of the DPMO metric is:
- It doesn't apply to service organizations.
- Defects aren't as important as profits.
- It can be artificially decreased by increasing the number of defect opportunities.
- All of the above.
Question 4
If you estimate your Cost of Quality as 7% of sales, and your overall DPMO is about 20,000, then:
- your Sigma Level is about 3.5.
- you are probably under-reporting the Cost of Quality.
- you should look for evidence of a Hidden Factory.
- All of the above.
Question 5
Six Sigma methodologies:
- can only be applied to companies who produce goods with large volume.
- concentrate on cost savings rather than customer needs.
- have not been successfully applied to service companies.
- None of the above.
Question 6
If a particular process has one critical characteristic, with a defect rate of about 2%:
- the process Sigma Level is about 3.5.
- the process Capability is about 1.6.
- the process Sigma Level is about 5.
- the process Sigma level cannot be determined from this defect rate.
Question 7
Examples of Hidden Factory losses include all of the following except:
- Capacity losses due to reworks and scrap.
- Stockpiling of raw material to accommodate poor yield.
- Rush deliveries.
- All of the above are examples of Hidden Factory losses.
