Boeing is going to be the case study of what happens when you let 'business people' take over an engineering company. A bunch of MBAs deciding to move numbers around on paper and losing sight of the bigger picture.
The 737 MAX and all the issues with the 787 isn't what happens when engineers are in charge, it's what happens at the end of a long line of non-technical people saying "well we can just do ______ right?" Cutting corners and working on influence rather than excellence.
Article detailing the debacle with the 787. From which zero was learned.
In 2001 there was an engineer that carefully analyzed the path Boeing was taking and detailed why it would cause nothing but increased risks and costs. A bunch of business guys outsourcing everything and not understanding why they don't have a working plane underneath all the contract language.
They had a goose laying golden eggs and they killed it to save the money on feeding it this quarter.
This paper, linked to from that page, also has some very interesting material in it, particularly on the use of RONA (Return On Net Assets) as a metric: http://seattletimes.nwsource.com/ABPub/2011/02/04/2014130646...
