A)requires that ±3σ (a total width of 6σ)of the product be within specification
B)requires that 99.5% of the product be within specification
C)contains a formalized problem-solving approach called Bayesian approach

Question

Quizplus · Accepted Answer

Six Sigma contains a formalized problem-solving approach called the DMAIC process, which stands for Define, Measure, Analyze, Improve, and Control. The other options are incorrect: A is not entirely accurate, as Six Sigma typically requires that 6σ (a total width of 12σ) of the product be within specification; B is also not entirely accurate, as Six Sigma typically targets achieving 99.99966% defect-free products (equivalent to 6σ); C is incorrect, as Bayesian approach is not the only problem-solving approach used in Six Sigma; and E is incorrect, as Six Sigma involves training employees at all levels of the organization.
