Process Control: Establishing standardized, measurable processes to ensure consistent results.
Continuous Improvement: Embracing a culture of continuous learning and iterative enhancements.

2. Introduction to the Six Sigma Methodology

At its heart, Six Sigma utilizes a structured problem-solving framework known as DMAIC:

Define: Clearly define the problem, identify customer requirements, and establish project scope.
Measure: Collect and analyze data to understand the current state of the process.
Analyze: Identify root causes of defects using statistical tools and logical reasoning.
Improve: Implement solutions to eliminate identified defects and optimize the process.
Control: Establish controls to ensure sustained improvement and prevent future issues.
