Answer 1

Six Σ refers to a description of the quality goal of no more than 3.4 defects per million opportunities and a quality improvement philosophy and program.

Step-by-step explanation:

Six Σ refers to the following:

• (a) A description of the quality goal of no more than 3.4 defects per million opportunities.
• (c) A quality improvement philosophy and program.

The term Six Σ comes from the statistical concept of standard deviation and is used to measure the variation in a process. It is a quality improvement methodology that aims to reduce defects and improve overall quality by identifying and eliminating causes of variation.

For example, in manufacturing, Six Σ can be used to minimize defects in the production process to achieve a target defect rate of no more than 3.4 defects per million opportunities (a). This goal reflects a high level of quality control and indicates that the process is operating at a very low level of variation.
