Cross-Functional Teams: Encouraging collaboration among individuals from different departments to leverage diverse perspectives.

2. Introduction to Six Sigma Methodology

At its core, Six Sigma utilizes a structured framework known as the DMAIC (Define, Measure, Analyze, Improve, Control) process to solve problems and enhance processes:

Define: Clearly identify the problem and define project goals.
Measure: Collect data on current process performance to establish a baseline.
Analyze: Use statistical tools to analyze data and identify root causes of defects or variations.
Improve: Implement solutions to address identified issues and improve process performance.
Control: Establish systems to monitor and maintain improved process performance over time.
