The term "Six Sigma" refers to the goal of achieving no more than 3.4 defects per million opportunities.

Introduction to Six Sigma Methodology:

At its core, Six Sigma involves a structured problem-solving process known as the DMAIC framework:

1. Define: Clearly define the problem and establish project goals.
2. Measure: Collect and analyze data to understand current process performance.
3. Analyze: Identify root causes of issues using statistical tools.
4. Improve: Implement solutions to enhance the process.
5. Control: Establish systems to maintain improvements over time.
