IASSC® Certified Lean Six Sigma Black Belt™ Quiz Questions and Answers
Answer :
Team Member Bios
Explanation :
While the problem statement, business case, and scope are integral to defining the project's purpose and goals, details like team member bios are not typically included in a Project Charter.--- I hope these questions and explanations are helpful for your needs related to the "Understanding Six Sigma " section of the Lean Six Sigma Black Belt course.
Identify and document the Critical to Quality (CTQ) elements.
Explanation :
The primary goal in the Define phase, particularly when engaging with cross-functional teams, is to understand what is critical to the customer by identifying CTQs. These CTQ elements are essential for guiding the project focus and ensuring alignment with customer expectations.---
Use factors easily manipulated in the real-world process
Explanation :
For a DOE to yield actionable insights, it is important to select control factors that can be feasibly and reliably manipulated in real-world scenarios, ensuring that the experimental conditions can translate effectively to process improvements.
They can reveal synergistic effects that can be leveraged for optimization
Explanation :
Interactions between factors in a factorial experiment can indicate synergistic effects where the combined influence of two or more factors leads to enhanced process performance, which can be leveraged for optimization efforts.
To determine the optimal conditions for achieving consistent quality
Explanation :
In DOE, examining cause-and-effect relationships helps to understand how different variables interact and influence process output, enabling the determination of optimal settings for consistent quality and process performance.
To empower them to take corrective actions and maintain process integrity
Explanation :
Proper training equips operators with the skills to recognize any signs of process deviation promptly, allowing them to take corrective measures to maintain control and ensure the output remains within desired specifications.
The SIPOC Diagram (Suppliers, Inputs, Process, Outputs, Customers) is used in the Define Phase to provide a high-level overview of the process, helping to identify key areas and stakeholders involved in the process flow.
Increased statistical power and interactions analysis
Explanation :
The primary advantage of a full factorial design is that it allows for the examination of interactions between all possible combinations of factors and levels, increasing the statistical power and depth of analysis.
A SIPOC diagram provides a high-level overview of the process flow by identifying Suppliers, Inputs, Process, Outputs, and Customers. It's an excellent tool for capturing the "as-is " state in the Define phase.---
To validate process enhancements and sustainment of quality
Explanation :
Statistically driven tools are essential for assessing whether process changes are genuinely effective and if the processes stay within control limits, ensuring continued quality and performance sustainment.
