<p class="MsoNormal">Yes, I totally agree. I think there needs to be a set of engineering requirements, that is combined with a set of planning artifacts. 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.
<br>
<br>
And I think I know of 1 major gap, IMHO: not all requirements are directly captured in the AP242 model. All geometry and PMI: yes, could be. 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?<br>
