Quick Definition:
Six Sigma is a set of techniques and tools for process improvement. It aims to improve the quality of the output of a process by identifying and removing the causes of defects and minimizing variability.
The DMAIC Framework
Six Sigma projects follow a structured five-phase process called DMAIC:
- Define: Define the problem and project goals.
- Measure: Measure the current process performance.
- Analyze: Analyze the data to find the root cause of defects.
- Improve: Improve the process by eliminating the root causes.
- Control: Control the improved process to ensure defects don’t return.
