At its core, Six Sigma methodology involves a structured problem-solving framework known as DMAIC (Define, Measure, Analyze, Improve, Control). This systematic approach ensures that projects are well-defined, measured, and executed with precision:

Define: Clearly understand the problem or opportunity for improvement, defining the scope and objectives of the project.
Measure: Collect and analyze data to establish a baseline performance metric and identify key process parameters.
Analyze: Pinpoint the root causes of defects and variability using statistical tools and methods.
Improve: Develop and implement solutions to address identified issues, testing and validating changes.
Control: Establish processes to sustain improvements, monitor performance, and prevent future deviations.
