Boeing in a serious bind?
Despite much deserved criticism of the manner in which Boeing has been operating in recent years (seemingly short-term profit maximisation and senior management perks at expense of all else), Boeing has accumulated immense aeronautical expertise; this embedded in the culture of its cadre of designers, engineers, and technical staff, and perpetuated by proven procedures and ways of doing things established during the course of the company's history. However, reputation is all. A series of (probably) avoidable misfortunes caused reputation to plummet and encouraged people knowledgeable about the industry to delve deeply into the company's current management culture, accounts, expectations, and procedures.
Boeing, similarly to other major defence contractors such as BAE Systems in the UK, has for decades led a charmed existence insulated from harsh realities of conducting business in a competitive market. The USA government has literally chucked money at Boeing and other defence contractors with little concern for detailed audit and considerations of value for money. Doubtless, many individuals in the higher echelons of Boeing and others in politics, government, and federal administration, have done very nicely from this but ultimately at expense of US citizenry.
In principle, largesse for defence manufacture could continue as is. However, Boeing manufacture for civil aviation in global markets looks to be in dire peril.
I suggest the only means of saving intact the intellectual and skill resource represented by Boeing is through the company filing for Chapter 11 insolvency. Placed into administration it would be feasible to dismiss Boeing's entire top management tier, to write-off stockholders, and to reorganise a slimmed down version with clearly defined business goals. Thereby the legacy of skill would be retained whilst abandoning a corrupted management ethos.
