Subject: Reliability Prediction
Message:
We all know that the result of reliability prodiction is much higher than the true reliability level.Does anyone know the proportion between them? Another problem is,a new product,has no reliability requirement from customer,how to decide the reliability requirement that the product should achieve? Thanks very much.

I would especially like to know if anyone has had any experience in how accurate the Bellcore predictions are. Agreed, the reliability predictions are conservative but by what factor (1.5, 2, or more). Also, I would presume the more data on the component you can give Bellcore the more accurate the prediction. If any has experience in the Method I Case 3 with electronic circuit boards they would be willing share, I would be grateful.
