Boeing was broken before it bought MDA. Starting with building airplanes without much idea of what that cost. Then real estate strung across the Puget Sound region, much of which was a cost, not investments with a return.
Buildings full of old equipment, tools, parts, and hardware stored for some forgotten reason that point to an illustrative problem, MBA's that don't bother with the BA part, and that is far from the only example.
Boeing had a reputation as a sorry engineering employer long before the buyout. The typical scenario at the end of the major engineering phase of a program was a layoff, while the program at another site could not fill seats. The layoff and subsequent departure of engineering staff at the end of the 777-300 program caused hiring problems for years.
BCA wants to engineer airliners with literally cook book analysis, and ignore features that don't fit the cookbook. I have first hand experience in that regard, and it's the reason I refused to sign drawings after the cookbook was filled out.
In any case, the current submission to the equality, inclusion, and diversity shakedowns has destroyed any pretension to ethics or morality; the corporation is shot through with the opposite.
Also, I'm convinced that new hires are screened for compliant personalities; the upshot of that is that they require hand holding at every step, are mostly poorly educated, and they simply can't think, analyze, solve problems, or invent design solutions.
