Hi All,
First I'd like to thank you all for the insightful comments which help clear things up, but still, I'm not sure I'm there yet.
I have a couple of questions which some of you perhaps could help with:
1. For software Verification and Validation testing, would you believe the rational of SW being a deterministic process, and thus having a 0 standard deviation would justify why pure SW testing is done on a sample size of 1 device?
2. When considering Design Verification and Validation, for an expensive piece of equipment, for example, an MRI scanner or a CT Scanner, it would probably not make sense to test 20-30 systems? how would you tackle this?
If a test protocol tests many different Variables, how would we go about explaining the sample size for it? for each variable a different sample size would be needed, and also, it should be defined while planning, before you have actual results.
I hope any of you could help clear things up.
Thanks
