Six Sigma & Process Improvement
CHAPTER 11
SIX SIGMA AND PROCESS IMPROVEMENT
TRUE/FALSE QUESTIONS
1. In Six Sigma, a problem is defined as a deviation between what should be happening and what actually is happening that is important enough to need correcting. Answer: T AACSB: Analytic Skills
2. Half the tolerance is equal to the distance from the target to the upper specification limit. Answer: T AACSB: Analytic Skills
3. A change in the quality level from 3-sigma to 4-sigma represents a five-fold improvement. Answer: F AACSB: Analytic Skills
4. 3.4 defects per million opportunities can occur with a quality level of 5-sigma if the mean shift is 0.5 standard deviations of the target. Answer: T AACSB: Reflective Thinking Skills
5. A Six Sigma quality level means that the difference between the upper and lower specification limits is six standard deviations. Answer: F AACSB: Analytic Skills
6. Six Sigma represents a quality level of 3.4 defects per million opportunities when the process mean is held exactly on target. Answer: F AACSB: Analytic Skills
7. Unstructured problems require more creative approaches to solving them than structured problems. Answer: T AACSB: Reflective Thinking Skills
8. The expectations of customers that matter most to them are known as “critical to quality” issues in Six Sigma terminology. Answer: T AACSB: Analytic Skills
9. Bottom-up projects generally are tied to business strategy and are aligned with customer needs. Answer: F AACSB: Reflective Thinking Skills
10. A Six Sigma project might span an entire division or be as narrow as a single production operation. Answer: T AACSB: Reflective Thinking Skills
11. One of the pitfalls experienced in organizations new to Six Sigma is the inability of senior managers to estimate what the resources, they allocate to Six Sigma projects, will “buy” in
