I think we have different ideas of "hitting their delivery targets" since Tesla has missed nearly every delivery target they've ever set for themselves...not just for the Model 3 but for the S and X as well. For the Model 3, theses misses are despite having a known number of customers years in advance of actually manufacturing the car.

Tesla has also had repeated issues delivering their cars to customers. And getting exported cars out of port (one of the most straightforward logistics functions a manufacturing company can manage). They still can't get replacement parts to many of their existing customers. These are all basic logistics failures that almost every other manufacturing company (carmakers and otherwise) has no problem handling.
