1-1. What does DMAIC stand for?
A. Define, Measure, Analyze, Implement, Continue
B. Develop, Metrics, Attributes, Identify, Control
C. Define, Measure, Analyze, Implement, Control
D. Define, Measure, Analyze, Improve, Control - Answer-1. D
Define, Measure, Analyze, Improve, Control are the 5 phases.
1-2. What is the objective of a Six Sigma project?
A. Reduce Variation
B. Reduce Variation and/or Shift the Mean
C. Shift the Mean
D. Eliminate waste - Answer-1-2. B
Depending on the project, Six Sigma can be used to both shift the mean and reduce
variation.
1-3. True or False: A Six Sigma Yellow Belt is equipped to lead a complex Six Sigma
project.
A. True
B. False - Answer-1-3. B
False. Six Sigma Yellow Belts are trained to lead localized projects and do not possess
the subject matter expertise to lead a complex project.
1-4. True or False: Keeping the Y=f(x) equation in mind, in order to improve a process,
focus should be placed on Y rather than the X's.
A. True
B. False - Answer-1-4. B
False. In order to see a shift in the Y metric, concentration must be placed on the X's.
1-5. True or False: Each phase of the Six Sigma DMAIC method has specific
deliverables that must be satisfied before moving into another phase.
A. True
B. False - Answer-1-5. A
, True. Each phase of DMAIC has specific tools and techniques that must be completed
with the Six Sigma Core Team and/or extended stakeholders in order to successfully
close out a phase.
2-1. Which of the following process maps is constructed in the Define Phase?
A. Detailed Process Map
B. Value Stream Map
C. Cross-Functional Map
D. SIPOC / COPIS - Answer-2-1. D
The SIPOC / COPIS is created during Define with the others in Measure and/or
Analyze.
2-2. True or False: When gathering the Voice of the Customer (VOC), both internal and
external stakeholders should be considered.
A. True
B. False - Answer-2-2. A
True. All perspectives of the process, product, or service in question should be
considered from both customer types.
2-3. True or False: When gathering the VOC, a VOC Plan should be completed by the
Six Sigma Belt leading the project.
A. True
B. False - Answer-2-3. B
False. The VOC Plan must be constructed with the entirety of the Six Sigma Core
Team.
2-4. True or False: The CTQ Tree is constructed using the VOC as input, which is then
translated into characteristics and attributes that can be measured.
A. True
B. False - Answer-2-4. A
True. The VOC serves as the pivot point, providing valuable insight into necessary
process characteristics needed to satisfy the VOC.
2-5. True or False: The Cost of Poor Quality Iceberg is important as it tells an
organization to focus on the issues and challenges which are already visible.
A. True
