Intuition-based decisions

Data-driven decision-making

The key principle that distinguishes Six Sigma methodology is data-driven decision-making. This approach emphasizes the importance of using statistical analysis and data to identify problems, measure performance, and analyze processes for improvement. In Six Sigma, decisions are based on objective evidence rather than subjective judgments or intuition. The goal is to eliminate defects and variability in processes by understanding and analyzing data, which leads to informed decisions that drive continuous improvement.

By relying on quantitative data and analytical tools, Six Sigma practitioners can accurately assess process performance, identify root causes of issues, and implement effective solutions. This focus on measurement and analysis is what sets Six Sigma apart from other methodologies that may rely more heavily on intuitive or qualitative assessments.
