Hello,
This is my first post here, so want to start with a thank you! I've been using Elsmar Cove since 2002 when I started my 1st (post Uni) job as a graduate quality engineer. Over the years I've never had to post a question - always found the answer I needed with a search. I'm now an STA/SQA Manager for an Automotive OEM and I'm back for some help with a project but can't find what I'm looking for. I know if anyone can help, it's the guys and girls at Elsmar Cove! So thank you for your support and enlightenment over the years and I look forward to hearing your experiences and opinions with my current topic: PV test planning
How to lay this out. I guess my problem statement / customer verbatim is something to the effect of:
This is clearly specific to my situation but I'd hazard a guess that more than a few of you recognise this complaint.
A little more detail:
In my place of work the Lead Product Development Engineer is responsible for setting the DV and PV test plan. The result is normally a PV test plan based on replication of previous plans (photocopy engineering) or just a repeat of DV. My STA seniors are quire happy to leave this to the PD tea but I'm sure I recall, in previous employment (6 years ago now), the STA team created the PV test plan based on PFMEA detection and recommended actions.
I've been reflecting on this for a few years now. I think there would be several benefits to having STA set the PV test plan:
Am I on to something? In your experience who's responsibility was PV test planning? Is there / can there ever be a pure link between PFMEA and the PV test plan?
Please wade in with your questions and comments.
Thanks, Mr Skeleton

How to lay this out. I guess my problem statement / customer verbatim is something to the effect of:
"PV test plans are ineffective and inefficient. They are created with little or no respect for the PFMEA and therefor the risk inherent in the process so are ineffective and wasteful".
This is clearly specific to my situation but I'd hazard a guess that more than a few of you recognise this complaint.

I've been reflecting on this for a few years now. I think there would be several benefits to having STA set the PV test plan:
- PD engineering not able to use PV testing as a "safety blanket" or to "top up" DV testing (pens down boys!)
- Test plan developed targeting only the risks that can't be controlled to acceptable level through measurement and in-process techniques therefore controlling cost
- test samples selected with understanding of the process variation factors and risk profile which could improve test effectiveness.
- Re-validation testing requirements better designed, more clearly understood and justified as part of the PFMEA and CP

It would be a good idea for you to spell out the abbreviations on first use in your post for the benefit of those who might not be familiar with them.
