Key Concepts and Principles
-
DMAIC Framework: The core of Six Sigma is the DMAIC methodology, which stands for Define, Measure, Analyze, Improve, and Control. This structured approach provides a systematic way to solve problems and improve processes.
-
Focus on Quality Improvement: Six Sigma aims to improve the quality of products and services by identifying and eliminating the root causes of defects and variations in processes.
-
Data-Driven Decision Making: Decisions in Six Sigma are based on data and statistical analysis rather than assumptions or guesswork. This ensures that improvements are quantifiable and sustainable.
-
Customer Focus: Six Sigma emphasizes understanding and meeting customer needs and expectations. The Voice of the Customer (VOC) is a critical component in defining project goals and objectives.
-
Team-Based Approach: Six Sigma projects are typically carried out by cross-functional teams led by individuals with specific roles, such as Green Belts, Black Belts, and Master Black Belts. These roles represent different levels of expertise and responsibility within the Six Sigma hierarchy.
