As a result of several field failure studies, evidence is clear that failure rates for the same product vary from site to site. The ratio ranged from 1.2X to 2X based on data to date. Therefore we conclude that random failures can be divided in to two categories – product specific and site specific. The differences seem to be related to site training, site procedures and other variables that some have called “Safety Culture.” exida defines this variable as the “Safety Maturity Index.” This webinar will provide an overview of some of the field failure studies, present a simplified model to evaluate Site Safety Index (SSI), and describe the safety impact of SSI.
