Capability Indices

Capability indices are statistical tools used to measure how well a manufacturing process produces items within specified quality limits. They compare the natural variation of the process to the allowable tolerance range, indicating whether the process is capable of consistently producing quality products. A higher index means the process reliably stays within specifications, while a lower index suggests more variability and potential for defects. These indices help organizations assess process performance, identify areas for improvement, and ensure products meet quality standards efficiently.
