Stability tests are a key Six Sigma tool used to evaluate the consistency and reliability of a process over time. By analyzing data collected from different time periods, stability tests determine if a process remains within control limits and operates predictably. These tests help identify trends, shifts, or variations that may indicate potential issues. Stability tests are crucial for ensuring continuous process performance, improving quality, and reducing variability. They support Six Sigma goals by providing insights into process behavior, guiding corrective actions, and maintaining consistent and high-quality outcomes, ultimately enhancing overall efficiency and effectiveness.
