Christopher Alexander on Feedback
“To make the feedback meaningful in a step-by-step process, the process must be open ended, hence partly unpredictable. It must lack a fixed predetermined end-state. This is necessary because adaptation itself means nothing if changes cannot be made in response to the process of adaptation. By definition, such changes cannot be foreseen.
… For a variety of reasons – legal, financial, and procedural – under modern conditions the thing is fixed too exactly, too far ahead, and has far too little freedom to unfold … It thereby shut off, nearly altogether, the possibility that useful testing or adaptation could occur …
This means not only that the end-result of a building project must be unpredictable during design. That is obvious. But to be effective in creating living structure, it cannot help also being unpredictable during construction.”
