Six Sigma is:

(A) a strategy that focuses on total customer satisfaction.
(B) a mathematical function that connects quality lost and cost.
(C) a program to reduce defects.
(D) a discipline that follows the DMAIC model.

Choose the correct answer from the options given below:

Correct option is C

Six Sigma is a data-driven methodology aimed at improving business processes by minimizing variation and reducing defects. It helps organizations achieve near-perfection in product and service quality. The correct statements are:

• (A) A strategy that focuses on total customer satisfaction:
  Six Sigma places customer satisfaction at its core by improving process quality, reducing defects, and enhancing overall efficiency. Customer needs and expectations are carefully analyzed, and improvements are implemented to align with them.

• (C) A program to reduce defects:
  One of Six Sigma's primary goals is to minimize process defects. It uses statistical tools and quality management techniques to reduce variability, ensuring that products and services meet high standards.

• (D) A discipline that follows the DMAIC model:
  Six Sigma follows a structured problem-solving approach known as DMAIC (Define, Measure, Analyze, Improve, Control). This model provides a systematic way to identify defects, analyze root causes, implement improvements, and sustain quality.

Information Booster:

• Six Sigma as a Strategy: It focuses on business process improvement by eliminating variations and aligning operations with customer expectations.

• Customer-Centric Approach: The ultimate goal is to enhance customer satisfaction by delivering defect-free products or services.

• Defect Reduction: By reducing process errors, Six Sigma improves efficiency, profitability, and reliability in manufacturing and services.

• DMAIC Framework: The DMAIC model ensures a structured approach to problem-solving, making Six Sigma highly effective.

• Statistical Foundations: Six Sigma relies on statistical data analysis to measure and improve quality.

• Business Application: Various industries, including manufacturing, healthcare, IT, and finance, use Six Sigma to optimize processes.

Additional Knowledge:

​(B) A mathematical function that connects quality loss and cost:
This statement refers to the Taguchi Loss Function, not Six Sigma. The Taguchi method evaluates how deviations from target performance affect cost and quality. While Six Sigma also considers cost reduction, it does not rely on this specific function.​
