The idea that engineers should build lego blocks without knowing what they're going to be used for is questionable at best. A better idea imho is to have small crossfunctional teams where scientists and engineers work together to build only what they need with short iteration cycles. If everyone involved doesn't have at least a broad perspective on the end-to-end purpose of what they're working on, they're probably going to build the wrong thing.
