The statistical methods, within Six Sigma, are designed to eliminate defects to a failure rate of ________ defects per one million opportunities, or a 99.9997% success rate.
A) 3.4
B) 34
C) 0.34
D) .344

Question

Quizplus · Accepted Answer

The correct answer is 3.4 defects per one million opportunities, which is denoted as DPMO (defects per million opportunities) and corresponds to a 99.9997% success rate. This level of quality is known as Six Sigma, which is the main goal of the methodology. Option B is a common mistake, as it represents 34 DPMO, which would correspond to a 99.9966% success rate, not meeting the stringent Six Sigma requirements. Option C and D are even further off, with error rates of 340,000 and 34,400 per million opportunities, respectively.
