Understanding the Economic Benefits of Measurement Uncertainty

Financial InstitutionFinancial implications would be the high-risk associated with companies using gage repeatability and reproducibility (GR&R) as their sole basis for measurement systems analysis. This limited method of analysis is not capable of capturing the full magnitude of measurement error and biases induced by many influencing factors. Measured results must be repeatable and reproducible, but by itself can be both a technical and financial risk. It is easy to have measured results that are repeatably and reproducibly incorrect, as uncorrected biases are easily induced that can be many times larger than the GR&R numbers initially recognized by the metrologist.

Customers and suppliers already know when this is occurring, as one of the two following situations happens: Measurement data can look good -- it complies with specification requirements, but the parts do not work or properly fit, or measurement data can look bad -- it does not comply with specification requirements, but the parts actually do work.

We call this the Understanding the Economic Benefits of Measurement Uncertainty.

IIGDT seminars focus on training all disciplines on how to identify key error sources that influence less than optimal decisions.
