I would be more interested in what mechanical and electrical engineers think about producing things than the opinions of political hacks.

You do realize GM was offering to produce ventilators but the hang up was contractual terms, not technical.
.
You also realize that GM is skilled in producing complex computerized machines in mass quantities.  I can assure you the average automobile has more than 1500 parts.

Don't quote idiots.

"Take one mechanical ventilator, the machine that's so critical.  To make one of those takes over 156 parts (he misspoke, it's 1500) that comes from at least 14 different countries and it's made, each of those parts, by experts who have the machines specifically for that part.  Suddenly to ask General Motors to do that is absolutely like asking you and me to go become brain surgeons because we at one time or another held a knife in our hands."  --The Last Word with Lawrence O'Donnell, 3/27

There are almost always problems when tooling up for a new manufacturing job and rolling out finished products. I'm sure that GM will be getting help from the company they are sub-contracting with (Ventec Life).

However, a process that works smoothly at a fully debugged facility in Washington (state) can not always be instantly duplicated someplace else.  As supply chains change, adjustments have to be made (e.g., sheet metal screws from new Company A aren't performing the same way as those from old Company B).  There is likely to be a slow start up to make sure everything is working as it should. As manufacturing problems arise, they need to be fixed on the fly.

I think GM can do this (and I hope I'm right), but I don't expect them to be up to speed on Day 1.

Which reminds me ... do any of you remember how the Japanese auto companies started clobbering the US auto companies, starting in the ~70s? Deming and Taguchi. For years, the US auto companies ignored Deming and his advice. The Japanese embraced his ideas.  
http://en.wikipedia.org/wiki/W._Edwards_Deming  
"Deming's teachings and philosophy are clearly illustrated by examining the results they produced after they were adopted by Japanese industry, as the following example shows. Ford Motor Company was simultaneously manufacturing a car model with transmissions made in Japan and the United States. Soon after the car model was on the market (c. 1950), Ford customers were requesting the model with Japanese transmissions over the US-made transmissions, and they were willing to wait for the Japanese model. As both transmissions were made to the same specifications, Ford engineers could not understand the customer preference for the model with Japanese transmissions."

If you need one (and I hope you don't), will you want to be sustained by a Ventec (made in Washington) ventilator or a GM (made in MI) ventilator?

Good point. But all of the defective airbags were made at their Mexico plant. The airbags made in their German factory were not defective.  
.
That does show that items manufactured to the same specs by the same or similar means at different factories do not always perform to the same standard.

To secure the BOM (Bill of materials or part needed to complete task) will be hard in the time they're saying. I think the quote or projection was to have 100,000 in 3 month vs the 29,000 in one year they get from what a regular suppliers can provide. That's what I pick up from yesterday's briefing.
GM is mostly automated with robotic machinery. To reprogram the system to maneuver in a tighter working area will be a challenge. They'll have to retrofit their machinery to accommodate the parts of the ventilator
The learning curve will take weeks but to secure the parts won't be easy.
I don't think GM was all in on this from the get go..they probably delayed this as far as they could.
My guess is in the end, they'll hire a bunch of guys, pay them $15.00 hour, non union. Give then a set of screw driver put them in a corner and let them have at it.
