Variability analysis

Variability analysis involves examining how different aspects of a process or system change over time. It helps identify patterns, sources of fluctuation, and consistency in data or performance. By understanding variability, organizations can determine whether changes are due to randomness or specific factors, enabling better decision-making. This analysis is crucial in quality control, manufacturing, and service delivery, as it highlights areas where processes can be stabilized or improved to ensure reliable and predictable outcomes.
