Understanding Six Sigma Concepts

What does the term "Six Sigma" refer to in quality management?

• A management style focused on employee performance

• A methodology aimed at reducing defects and improving process quality

• A financial strategy for reducing production costs

• A software tool used for project management

What is a "defect" in the context of Six Sigma?

• Any product that is returned by a customer

• A failure to meet a required specification or standard

• A delay in the production process

• An increase in the cost of manufacturing

What does DPMO stand for?

• Defects Per Manufacturing Output

• Defects Per Million Opportunities

• Defects Per Measured Operation

• Defects Per Maximum Output

What does DPU stand for in Six Sigma quality measurement?

• Defects Per Unit

• Defects Per Utilization

• Defects Per Uniform

• Defects Per Usage

Which of the following is the correct formula for calculating DPMO?

Which of the following is the correct formula for calculating DPU?

At the Six Sigma level of quality, approximately how many defects per million opportunities (DPMO) are allowed?

• 3,400

• 66,807

• 10,000

• 233,000

Which of the following best describes the primary goal of quality control in Six Sigma?

• To increase the speed of production

• To minimize process variation and reduce defects

• To maximize the number of products manufactured

• To reduce the number of employees in a process

• Mean

• Variance

• Standard deviation

• Median

If a process produces 20 defects in 500 units, what is the DPU?
