The Product/Market Fit Survey (PMF) specifically asks the customer, “How would you feel if you could no longer use this product?” with a multiple choice response. The survey is often used as a proxy metric for PMF. If 40 percent or more customers answer they would be “very disappointed” without the product, then it is assumed the product is ready for marketing to the entire segment that answers that way.
