    I am seeing a new thing show up. Instead of calculating RPN as Sev * Occ * Det, there is now an RPL that gives you are result of 1, 2 or 3 (1 being bad, or priority 1 to address). You don't multiply, there's three tables, basically. A Severity x Occurrence table, which gives an intermediate result. And a Severity x Detection table, which gives a second intermediate result. Take these two into a third table and get your RPL level.

    So far I have only seen one OEM mention it.

    Anyone else seeing this? Is it getting traction?

    For what it's worth, it makes a whole lot more sense.

    I did see that AIAG has a project to align their FMEA and the VDA FMEA. Maybe its coming from there.
