[step-manufacturing] EXTERNAL: Call reminder: Time for Plan B?

[Thomas Thurman]

Jan,
AP 242 is capable of being a reference schema for exchanging the requirements you cite, including references to specifications and standards.
I haven't looked but expect there are recommended practices in the PLM-IF area.

Best regards,

Those artifacts are (in theory) all that is needed for successful instantiation. Combined, they ought to be enough to drive direct manufacturing as you propose. I believe that an AP242, combined with an AP238/QIF-plan ought to be enough for driving execution. If not, we need to identify the gaps and work towards closing those.

But in order to create successful plans (both for mfg and test), you also need requirements that are driven by specifications and standards. How do you capture those? Today, specs and standards are in some form of "prose" ("pdf, TXT, DOCX"). Very difficult to distill true requirement from that, unless you are a human interpreter. How do we create "machine-readable" artifacts from those specs and standards? Or to what do we convert them so we can reason on that information?
