What does DMAIC stand for in Six Sigma?
Answer: Define, Measure, Analyze, Improve, Control
DMAIC is the structured Six Sigma problem-solving methodology: Define, Measure, Analyze, Improve, Control.
A Six Sigma process has a defect rate of approximately:
Answer: 3.4 defects per million opportunities
Six Sigma quality corresponds to no more than 3.4 defects per million opportunities (DPMO), representing near-perfect quality.
In Six Sigma, what is a 'Black Belt'?
Answer: A full-time Six Sigma practitioner trained to lead improvement projects
Black Belts are certified Six Sigma experts who lead complex improvement projects and mentor Green Belts.
What is the purpose of a process capability study?
Answer: Assess how well a process meets specification requirements statistically
A process capability study uses Cp, Cpk, and related indices to quantify the ability of a process to produce within specifications.
In the Measure phase of DMAIC, the primary goal is to:
Answer: Establish a baseline performance measurement for the process
The Measure phase quantifies current process performance to establish a data-driven baseline before analysis begins.
What is a 'sigma level' used to describe?
Answer: How many standard deviations a process fits between its mean and specification limits
Sigma level indicates process performance by measuring the distance between the process mean and specification limits in standard deviations.
