Can You Assure a Successful Outsource?

Just like any other contractor give them a little after all the legal paper work is done and see how they do then increase a little until you postive they can handel the load. But keep a close eye on them with spot checks and constant Quality Control checks.

but outsources are not new topic in the world.

Assure no, but you can severly minimize your risk. If you have a well definined product (drawings) you supplier's have no choice but to make the parts and product that you want. If they don't you may have delays in your product launch, but at least your not paying for the failure (and retooling) that cause your delay. Our world and the global economy would quickly grind to a halt if we couldn't outsource some work. In part because no company can afford to be the technical expert in all the technology they need. Airplanes need hydraulics, materials engineering, electical systems, mechanical systems, ergonomic features, etc. Neither Boeing nor Airbus hold the industrial leading position in all theses areas, but they can define the parameters of there needs clearly and in no uncertain terms such that their suppliers are forced to provide acceptable components.
