exida Recorded Webinars

Using Manufacturer Warranty Failure Data (Not)

Recording Date: August 2018

For decades manufacturers have been using their customer return data to estimate failure rates for their products. exida also uses this data but only for comparison and validation purposes. This webinar will show the result of several of our recent warranty failure calculations and the comparison to the corresponding FMEDA prediction for the same product. We will show how the data is useful for calibrating a component database. We will show why warranty data is not a useful method for realistic failure rates used for safety verification calculations.
