Ackoff, Idealized Design and Bell Labs

Idealized design is a way of thinking about change that is deceptively simple to state: In solving problems of virtually any kind, the way to get the best outcome is to imagine what the ideal solution would be and then work backward to where you are today. This ensures that you do not erect imaginary obstacles before you even know what the ideal is.

“Doesn’t it strike you as odd,” he said, “that the three most important contributions this laboratory has ever made to telephonic communications were made before any of you were born? What have you been doing?” he asked. “I’ll tell you,” he said. “You have been improving the parts of the system taken separately, but you have not significantly improved the system as a whole. The deficiency,” he said, “is not yours but mine. We’ve had the wrong research-and-development strategy. We’ve been focusing on improving parts of the system rather than focusing on the system as a whole. As a result, we have been improving the parts, but not the whole.

We have got to restart by focusing on designing the whole and then designing parts that fit it rather than vice versa. Therefore, gentlemen, we are going to begin by designing the system with which we would replace the existing system right now if we were free to replace it with whatever system we wanted, subject to only two not-very-restrictive constraints.
