I prefer the Electrical Engineering's phase "Impedance matching". "In electronics, impedance matching is the practice of designing the input impedance of an electrical load or the output impedance of its corresponding signal source to maximize the power transfer or minimize signal reflection from the load." This basic control system theory that is applicable to Electrical and Mechanical System design. More and more I believe it is applicable to Business System. In product / business development, I like to think the term as "Don't waste $, time, human resource on scaling Marketing/Sales, until one is reasonable certain that the product is ready product marketing fit is validated in small scale."
