Managing the Design Factory was, i thought, very good. It succinctly and clearly gives one the lay of the land. It starts by taking the perspective that everything costs money, and the Design Factory should be aware of this and should look at the bottom line as much as anything else. Then it goes through the ideas, models, metrics, systems, organizations, architectures, customer interactions, et. al. that the author sees as crucial to respecting that bottom line. Not just in the sense of making things on the cheap, but trying to make something terrific for the customer yet affordable and respectful of the people doing the work all along the way.
