49 Review We have seen how we can track individual components from the supplier to the cell phone manufacturer. We have seen how all the parts can be tracked to an individual phone all the way to the customer. We have seen that vision is a crucial component to guide the assembly of parts and the cell phone as a whole. We have seen that vision can also play an important role in verifying the quality of the phone. 49
