Validating a Market Problem
Our team is struggling with a question internally: How many potential end points (prospects/customers) does a enterprise- level, B2B, market-driven product manager need to talk to in order to validate a market problem?
According to research specialists, 31 is the smallest statistically valid sample.
Realistically, more customer interviews are better than fewer, don't you think? We recommend three interviews to teach you what you don't already know, supplemented with survey research to determine which of the problems is most statically relevant.
