Closing the Loop

Chris Anderson: “If we could measure the world, how would we manage it differently? This is a question we’ve been asking ourselves in the digital realm since the birth of the Internet. Our digital lives—clicks, histories, and cookies—can now be measured beautifully. The feedback loop is complete; it’s called closing the loop. As you know, we can only manage what we can measure. We’re now measuring on-screen activity beautifully, but most of the world is not on screens.

As we get better and better at measuring the world—wearables, Internet of Things, cars, satellites, drones, sensors—we are going to be able to close the loop in industry, agriculture, and the environment. We’re going to start to find out what the consequences of our actions are and, presumably, we’ll take smarter actions as a result. This journey with the Internet that we started more than twenty years ago is now extending to the physical world. Every industry is going to have to ask the same questions: What do we want to measure? What do we do with that data? How can we manage things differently once we have that data? This notion of closing the loop everywhere is perhaps the biggest endeavor of our age.

Closing the loop is a phrase used in robotics. Open-loop systems are when you take an action and you can’t measure the results—there’s no feedback. Closed-loop systems are when you take an action, you measure the results, and you change your action accordingly. Systems with closed loops have feedback loops; they self-adjust and quickly stabilize in optimal conditions. Systems with open loops overshoot; they miss it entirely…(More)”
