I think the primary purpose of such stress tests is also to determine what a Supplier can achieve, relative to what they say they can do. If someone says they can get you 2,000 units per week, but they can actually come through with 3,000 per week, all is good. If the first supplier can actually only deliver 1,500 per week, hold them to that standard, then find someone else who can also deliver 1,500 per week and use them too. That way no one gets 'fired' though they may make less money per month. On the other hand, if someone says they can deliver 2,000 units per week, and after multiple delays they still haven't reached 300 units per week...? Well, yeah... You fire those guys.Of course mine was an oversemplification, i don't think tesla will ever sacrifice quality for time, but again, if you know that a partner isn't going to deliver and can't keep you pace, then you simply drop it and find another with the same quality. You just can't afford to keep a partner that isn't keeping pace or deliver a wrost quality or similar ( just think of mobileye )
When there isn't available partner with the right quality, they simply build it in house, like they have already done, but at this time they simply can't miss the model 3 deadline, too much is at stake this ( or better.. they can't miss it by too much )
