Salespeople pride themselves on being able to sell anything to anybody. The consumer , however, may not need the product which is being marketed. Look, for example, at those really fun machines which you can buy to sort coins into rolls. Neither banks nor stores want coins that have been wrapped by consumers. Banks want to sort and wrap their own, and stores want theirs only from banks.
Usefulness is, therefore, pretty limited.
Most products are designed by either engineers or, in the case of forms, bureaucrats. The engineers are trying to invent something from a technological standpoint, not from a user's need . Someplace in the design stage, usability testing has to take place, but, too often, it doesn't. In this case, the company loses money because it has already tooled up to make a product one way, maybe even produced one or more runs, and, now, it has to start over. It would have been cheaper for the company to have hired a consumer usability expert to interview users and do usability testing on the product.
