Six Sigma Green Belt Certification Practice Exam

Which of the following goals is most closely aligned with the principles of Six Sigma?

1. Reducing product defects by more than 10%

2. Increasing product prices to manage profitability

3. Improving employee satisfaction scores

4. Expanding production capacity to meet demand

The correct answer is: Reducing product defects by more than 10%

The goal of reducing product defects by more than 10% aligns closely with the principles of Six Sigma, which is fundamentally centered around the reduction of variability and the enhancement of quality in processes. Six Sigma methodologies focus extensively on identifying and eliminating the causes of defects and errors in manufacturing and business processes, thus improving overall quality and performance. By aiming to reduce defects, organizations can achieve higher levels of consistency in their products or services, ultimately leading to higher customer satisfaction and lower costs associated with waste and rework. This goal reflects the core philosophy of Six Sigma, which emphasizes using data-driven approaches to improve processes, thereby achieving near perfection in quality (often defined as 3.4 defects per million opportunities). Other options, while they may have value in a broader business context, do not directly encapsulate the essence of Six Sigma principles. Increasing product prices targets financial aspects rather than quality improvement, improving employee satisfaction scores is a vital aspect of overall organizational health but not directly linked to the Six Sigma focus on process quality and defects, and expanding production capacity addresses demand without inherently aiming to enhance the quality and reliability of the production processes themselves.
