Normally I hate anything moving on a page, but these are great.
So yeah, lots of places to hide laziness.... And near impossible to have cross domain programmatic checks.
Theres also major differences in architecture of avionics, how tooling works, which vendors supply what between all the different aircraft. Remember, Boeing tried this idea of commonality between product lines in the 757/767 project and the approach has since fallen out of favor.
Some businesses can get away with operating with a culture lacking personal ownership and accountability for much longer when it's harder to hide cut corners, because it's easier to encode business rules to enforce accountability.
So to me, what makes Boeing's case so news worthy is of course the stakes being so high, and also the fact that the engineering culture that was sacrificed wasn't just a nice to have, it was essential, and no amount of MBA business rules can make up for it.
another example of short-term benefits, making shareholder happy and MBA getting nice bonuses, ending up with destroyed planes, killed people, and a reputation in the gutter.
another one to add to the already thousand-lines long list of MBA and short-term stupid people only interested by money achievements.
