hi everyone,
(not too sure if i should post this here or in the ATE threads or in SPC topics on practical significance)
my supplemental scenario is: NDC calculation is required as per CSR or internal requirement, and it fails (<5). However, the situation is that effective resolution cannot be further improved, ie. ATE is of new technology (same situation in AIAG MSA 3rd ed, page 46). The ATE also measures devices with very small variability, ie. went through highly capable processes before testing.
my question: can i use a practical significance concept to decide that i ignore an ndc < 5?
thanks!
