Not back II

In the context of the new plane program, flightblogger notes a couple of recent developments that were mentioned in public announcements this week. For each of the below, the comments are well worth a browse.

• Rework (April 27, 2011) -- evidently, all of the planes that have been manufactured, to date, need some changes dealing with handling lightening. One estimate said weeks of work per each. Too, there will be schedule issues, but does the current plan allow for things taking longer, in some cases, than expected? One comment mentions that relaxing along all decisional axes is almost guaranteed to raise problems. Similar statements (Rush job) here, earlier.
• Break even (April 28, 2011) -- as the plane moves toward release, discussions will turn from technical issues to the economic ones. How one handles rework (prior Bullet) very much has to do with cost as well as with knowledge; confounding issues can arise along the whole development timeline, as we have seen. From a continual improvement viewpoint, one hopes that lessons learned carry forward.

It would be interesting to see Boeing lead in efforts to understand, for the betterment of all, when human and computational knowledge are not equivalent. And, that would deal with several subjects (things in themselves, model limits, Turing space, and more).

Again, there a parallels between plane engineering and the thing called financial engineering sufficient to allow some interesting discussion. This can continue (even while being 'not back').
