Reminded me also of the Taguchi loss function. To paraphrase, quality is optimized when you manage the variation of a measurement in relation to its target value, instead of emphasizing the acceptable limits. It was seen as an improvement over the "goalpost" approach. And while you can say it really applies in manufacturing context, I think it should be considered more broadly for goal-oriented measurement and engineering in general. https://en.wikipedia.org/wiki/Taguchi_loss_function https://en.wikipedia.org/wiki/Taguchi_loss_function
