Gauge R&R: how much variation is the gauge?
A gauge R&R study separates measurement error from real part-to-part variation, so you can tell whether a tolerance decision is trustworthy.
Structured analysis of failure modes, effects, and risk controls.
Failure Modes and Effects Analysis: a structured review of how a product, process, or asset can fail, what causes each failure, and how severe, likely, and detectable it is. Actions reduce risk before failures reach production.
