What GM needs to do is have their plants be able to manufacture every product they sell. Look at BMW's Spartenburg plant. They build the X5 and X6 side by side and the now disconutined US built Z4. BMW can techinally build just about any model there if they wanted too. Aslo look at Nissan's plant in TN. Nissan builds the Altima, Maxima, Frontier/Suzuki Equator, Pathfinder and Xterra in the same building. Does GM really do the same?
GM does not utilize a true flexible manufacturing facility in the production of its vehicles. Of course, the practice a form of this by re-badging a Chevy as a Buick and a Saturn. They can shift production between the different brands of the same vehicle as demand warrants.
In any event, we're really in agreement about different parts of the bigger GM mess. I think they need to downsize; you believe they need to work smarter, not harder, so to speak. I also agree they need flexible manufacturing but that, in itself, will not help GM right now. Cutting production capacity by 60% will.
10 years from now when we re-examine this period in GM's history we will look to GM leadership (CEO Wagner and the Board of Directors) who played the part of the consummate addict; refusing to believe they had a problem until it was too late. Even Friday CEO Rick Wagner refused to admit that with only 60 days of cash on hand it was not yet time to CONSIDER filing for bankruptcy protection. Not even a bailout of $25B would be sufficient to turn the tide for GM as its currently structured.
Evidence: GM had ~$40b cash on hand about 18 months ago. At the time they believed that the (then) new GMT-900 trucks and SUVs, the Malibu/Aura/G6 cars, the Volt and the Solstice/Sky would generate sufficient profits to save GM. In the ensuing months, before the economy tanked, GM was shedding market share like crazy, renegotiated a sweet deal for the unions, and spun-off then bailed-out Delphi.
Today, GM has effectively no high-volume new cars in development, no cash to update faltering models (Cobalt, G6, Impala, Colorado, Solstice, etc) and assets left to sell or put-up as collateral. They literally are trying to sell the shirts on their backs (RenCen). Not protecting the share-holders and other GM creditors through Bankruptcy is dereliction of duty by any definition for Rick Wagner.
I just can't wait for the books and inevitable movie to come out. These are going to make
The Smartest Guys in the Room (about the rise and fall of Enron) look like tales of the high school lunch room.
