What does the Kano Model classify as 'delighters' or 'attractive quality' attributes?
Answer: Features that increase satisfaction when present but do not cause dissatisfaction when absent
Delighters in the Kano Model are unexpected features that greatly increase satisfaction when present but cause no dissatisfaction when missing.
In a regression analysis, what does a Variance Inflation Factor (VIF) greater than 10 typically indicate?
Answer: Severe multicollinearity among predictor variables
A VIF exceeding 10 signals that a predictor variable is highly correlated with other predictors, indicating severe multicollinearity.
During the Control phase, what is the primary purpose of a control plan?
Answer: To document the system for monitoring and maintaining process improvements
A control plan documents the monitoring methods, specifications, reaction plans, and responsibilities needed to sustain process improvements.
What is the purpose of the Box-Cox transformation in Six Sigma analysis?
Answer: To transform non-normal data into an approximately normal distribution
The Box-Cox transformation applies a power function to data to make it more closely follow a normal distribution for valid statistical analysis.
Which metric represents the expected number of defects per million opportunities at a 4.5 sigma short-term shift?
Answer: 3.4 DPMO
The Six Sigma benchmark of 3.4 DPMO corresponds to a 6 sigma process with a 1.5 sigma shift, equivalent to 4.5 sigma short-term performance.
What is the main advantage of using a fractional factorial design instead of a full factorial design?
Answer: It requires fewer experimental runs while still estimating main effects
Fractional factorial designs reduce the number of runs needed by sacrificing the ability to estimate some higher-order interactions while preserving main effect estimates.
