Re: (DenCo)
Lemme try to set this straight once and for all.
1) Within the Auto industry (GM included) there are hundreds of types of engineers involved with the design of every aspect of the auto. This doesn't include MFG & ASM engineers, either. There are hundreds of parts and thus hundreds of engineers. Of course they don't all work in one place... heck, they don't work in one company, because many parts are sourced from suppliers.
2) Within GM (as with other companies with the similar global reach - Ford), there is NO SUCH THING as a COMPLETE amalgum of these engineers in any one region. Be it architecure or platform... chassis or suspension... frame or panels... engine or transmission... FEA or design... validation or development... calibration or testing... it goes on and on and on and on. You cannot even make heads or tails of the Org Chart, because there are so many intertwining links and cross matrixing of people and responsibilities across the global units it ain't funny. The point is NO region has a complete set of people to do the job (due to various reasons - business, personal, fate, etc.).
3) Some regional units have more resources than other with a particular function (validation, testing, FEA, architecture design, studio design, body sealer engineering!). Some have less resources. Some have NADA.
Given all of the above, projects are supported as required. There are regions assigned a particular platform (a subset of the vehicle architecture... the specific model on that architecture), because... well... it makes sense to spread the work... be it justified by experience, need to spread work (uhhh... efficiency?), ain't nobody else got time, economics, the market, etc. Since resources are not thorough... it only makes sense that any and all projects will see varying levels of SUPPORT from other regions... from a little to HOLY ****, I need some help, ASAP!!!
From the top levels of platform/vehicle leadership down to the grunt manning the dyno cell or the tube jockey waiting for the FEA to finish... the nationality varies as does one's actual physical locale. You could have a foreigner working in a different region, teaching or aiding said region with your personal, home-grown skill set (American, Korean, German, French, Australian, Mexican, etc.)... or vice versa.
For people to speak as if any one region is special or particularly better talented or engineers anything better is laughable at best, because the overlap of SHARED work across the projects is growing more and more everyday.
For those who think an Epsilon for a Vectra may be better than one for a Malibu should think twice, because you have no idea what people were involved (ex. My Chaldean-American buddy who works in B&W MFG Engineering has had US & global projects to work on. Then there is my buddies in Mexico, Australia, China, and Korea representing their home-grown skillz abroad. Heck, you can include myself and my wife for that matter down here in Mexico. My wife manages a GLOBAL team of purchasing buyers in US, Mexico, Brazil, Korea, and Germany.
No region (US-included) is a COMPLETE organization. It doesn't need to be, because there is too much capacity as is in the industry. Given that, it is sensible/obvious to see the work being spread globally in order to best UTILIZE the resource capacity you have in Engineering. This is no different than trying to fully utilize the HOURLY capacity you have. In MFG, the term for the individual jobs is WORK ELEMENT. There are some work elements that are "TRANSFERABLE" (i.e. It doesn't matter where in the process of MFG or ASM you do it, because it is not sequencially special to the overall part. The SAME goes for engineering... work elements. With today's internet and speed of communciations, CAD/etc. can be sent around the world to be done and returned or transferred somewhere else to continue the work.
