What is Shainin?

Shainin is a problem-solving methodology focused on quickly identifying and verifying the root causes of product or process variation. It employs tools like Red X, Multi-Vari charts, and B vs C comparisons to narrow down potential causes efficiently, often without requiring extensive statistical expertise. It is commonly used in manufacturing and engineering environments to improve quality, reduce defects, and enhance process robustness by targeting the most significant contributors to variability.
