I'm likewise skeptical. I've done a number of projects for Boeing, and their engineers are some of the most cautious and careful customers I have ever had. Automotive tier-one customers need it done on time and under budget, no matter the shortcuts required to make that happen, but if the junior janitor at Boeing sees something he feels is maybe suboptimal we'll halt the project and fully study the concern. I keep my schedule clear for 2 months after an aerospace project is supposed to be done, because it probably won't be, and it will be better for it.
I just can't square these experiences with this news. Perhaps design and manufacturing are more siloed than I understand, or perhaps there really is an MBA culture running requirements and certification separate from the engineering of the physical components, but in my personal experience Boeing isn't a place that cuts corners.
