Six Sigma aims to achieve $3.4$ or fewer errors per million opportunities.
True
Motorola was the first company to implement Six Sigma in the mid-1990s.
False
The ultimate goal of Six Sigma is to achieve a culture of continual improvement.
True
Six Sigma focuses solely on reducing defects in manufacturing processes.
False
General Electric experienced rapid growth and interest in Six Sigma after initially implementing it.
True
The term 'dpmo' refers to the number of defects per million opportunities.
True
Six Sigma principles emphasize the use of quantifiable metrics like defects per million opportunities (dpmo) across all organizational functions.
True
Six Sigma projects do not require extensive training for team members before deployment.
False
Creating highly qualified process improvement experts like Green Belts and Black Belts is a principle of Six Sigma.
True
Six Sigma principles discourage setting stretch objectives for improvement projects.
False
Focusing on key business processes and customer requirements is not a principle of Six Sigma.
False
Corporate sponsors play no role in Six Sigma projects according to the principles.
False
Six Sigma is focused solely on statistical methods, while TQM relies on worker empowerment and teams.
False
The equation $k \times \sigma = \frac{1}{2}\sigma$ represents the relationship between the sigma level and the tolerance range in Six Sigma.
True
TQM activities are generally limited to simple improvement tools and concepts, while Six Sigma focuses on a more rigorous set of statistical methods.
True
The primary difference between Six Sigma and TQM is that Six Sigma projects are confined within a single function or process, while TQM activities span across multiple functions.
False
Both Six Sigma and TQM place equal emphasis on financial accountability and a verifiable return on investment.
False
The equation for calculating the sigma level involves the process standard deviation and the tolerance range.
True
Green Belts are fully-trained Six Sigma experts who perform technical analysis on a full-time basis.
False
Return on Quality (ROQ) involves balancing quality costs against expected revenue gains.
True
The Six Sigma methodology considers quality efforts to always be valid, regardless of cost.
False
Team Members in Six Sigma projects are individuals from various functional areas who support specific projects.
True
$2^{10}$ is equal to 1024.
True
In the Six Sigma methodology, root cause analysis focuses on identifying and addressing symptoms rather than underlying causes.
False
Brainstorming is a group problem-solving procedure for generating a large number of ideas through combination and enhancement of existing ideas.
True
The text mentions that the primary purpose of the PDSA cycle is to establish new standards and procedures, train the workforce, and institute controls to ensure improvements do not die over time.
False
