Six Sigma is a set of techniques and tools for process improvement. It was developed by Motorola in the 1980s and has since been adopted by many organizations worldwide. The goal of Six Sigma is to improve the quality of process outputs by identifying and removing causes of defects and minimizing variability in manufacturing and business processes.
Key Principles of Six Sigma
- DMAIC: Define, Measure, Analyze, Improve, Control. This is the basic framework used in Six Sigma projects.
- DMAIC Tools: These include statistical tools like regression analysis, hypothesis testing, and control charts.
- Lean Principles: Lean Six Sigma combines the principles of Lean with Six Sigma to reduce waste and improve efficiency.

- Increased Customer Satisfaction: Higher quality products and services lead to increased customer satisfaction.
