Choosing design settings to minimize the effect of noise is a goal of
Answer : A
Robust design focuses on improving the quality of a product by minimizing the effects of variations without eliminating the causes of those variations.
Robust Design:
Techniques to make products or processes less sensitive to variations.
Aim to ensure performance under a wide range of conditions.
Tolerance Design:
Setting acceptable ranges of variation for product dimensions or performance metrics.
Design Verification:
Testing and validating that a design meets its requirements.
Design for Maintainability:
Designing products to be easy to maintain and repair.
Choosing design settings to minimize the effect of noise aligns with robust design principles.
Question 2
A production line has job aids that outline, step by step, how to perform the tasks of the job. This is followed by each of the operators working on the line. This is an example of
Answer : C
Standardized work involves documenting and following the best practices for performing tasks on the production line.
Job aids that outline step-by-step instructions ensure consistency and quality in task performance.
This practice helps in maintaining uniformity and reducing variability in the production process.
Reference: Lean manufacturing literature, such as 'The Lean Manufacturing Pocket Handbook,' describes standardized work as a core principle for ensuring efficiency and quality.
Question 3
How many total degrees of freedom are in an unreplicated 23 factorial experiment?
Answer : B
In an unreplicated 232^323 factorial experiment, there are 8 runs (since 23=82^3 = 823=8). The total degrees of freedom are calculated as the number of runs minus 1, which is 81=78 - 1 = 781=7. However, considering there are three factors, each with one degree of freedom, and their interactions (1 for each main effect, 3 two-way interactions, and 1 three-way interaction), the correct total degrees of freedom are 7.

Question 4
During the causes of a problem have been verified in the analysis phase of a six sigma project, they will form the basis of the solution in Much of the following phases?
Answer : C
In Six Sigma projects, the phases are defined by DMAIC (Define, Measure, Analyze, Improve, Control).
Control:
Ensures the improvements are sustained over time but does not primarily focus on implementing the solutions.
Define:
Focuses on defining the problem and project scope.
Improve:
This phase is where solutions are developed and implemented based on the analysis.
Verified causes identified in the analysis phase are used to create solutions during the improve phase.
Measure:
Involves quantifying the problem but not implementing solutions.
Question 5
The risk priority number (RPN) is determined by the
Answer : D
The Risk Priority Number (RPN) in FMEA is determined by the product of the frequency of occurrence, severity, and detection ratings. This multiplication helps in quantifying the risk associated with each potential failure mode, allowing for prioritization of corrective actions based on the highest risk areas.

Question 6
The Malcolm Baldrige framework evaluates an organization's
Answer : A
The Malcolm Baldrige framework evaluates an organization's approach and results. It assesses how the organization approaches various aspects of quality and performance management and the results achieved through these approaches. This comprehensive evaluation helps organizations understand their strengths and areas for improvement. Reference: 'The Malcolm Baldrige National Quality Award Criteria for Performance Excellence,' which outlines the evaluation criteria focusing on approach and results.
Question 7
The primary purpose of the material review board is to
Answer : C
The primary purpose of the Material Review Board (MRB) is to review and determine the appropriate disposition of nonconforming products. The MRB evaluates the nonconformities, decides whether the products can be reworked, used as-is, or must be scrapped, and ensures that corrective actions are implemented to prevent recurrence.
