Quality information framework quantifying and minimising uncertainty

The quality information framework (QIF) is an ANSI and ISO information standard developed by the Digital Metrology Standards Consortium. When QIF was being developed, one of the aims was to make quality engineers as confident as possible in the data used to assess the quality of manufactured products. With that aim, a set of types of uncertainty about the data used to assess product quality was identified, and provisions of QIF were built to address them. This paper describes how QIF handles both aleatoric and epistemic uncertainties.
