Performing site audits for numerous customers can be very telling. All sites have their own unique layout, procedures, documentation, and people. Did you know that failure rates differ from site to site? Are you surprised? According to our recent webinar results, the majority of people aren’t, and in fact they expect it. If this is the case, then why isn’t anyone taking into account these factors?
This is how the Site Safety Index (SSI) started.
Over the last 30 years exida has accumulated over 200 billion operating hours of REAL failure data. From this data, exida was able to create the SSI. A number of field failure studies have shown that the failure rate for identical modules in the same industry application have indicated there is a difference in failure rates for the same product from site to site.
Typically the ratio is averaging between 1.2 and 3 times difference depending on product type.
