But I can't look at the design from my desk-mate and hope to understand it quickly. We wall love to invent as much as possible ourselves, and we lack a common design language for the spaces we are problem solving in. Personally I don't entirely think it's a problem of discipline of software engineering, but a reflection of the fact that the space of possible solutions is so high for software, and the [opportunity] cost of missing a great solution because it is too different from previous solutions is so high (difference between 120 seconds application start and 120 milliseconds application start, for instance).
