The 1997 merger that paved the way for the Boeing 737 Max crisis (2020)

I'd also add Flying Blind by Peter Robinson, a book written specifically about the demise of Boeing's culture and how it translated into the 737 Max disaster.

Out-Sourced Profits: The Cornerstone of Successful Subcontracting by L. J. Hart-Smith, an engineer at Boeing's Phantom Works unit during that transition period, was a internal paper that walks through one of the many disputes between Boeing and Douglas/GE culture and derives why the Boeing way was correct.
