With the help of his neighbor’s un-used food truck, David has developed a cheap and simple prototype of his service. Now David can take the truck to his potential customers, like a Prototype Roadshow, and see what they really think.If the responses to David’s Prototype Test had come back negative, what could have possibly been the reason? Perhaps the pain in obtaining a food truck was not big enough for people to care. Or maybe David misunderstood the pain and therefore developed a misguided solution. Or it’s possible that David’s solution simply wasn’t good at solving the customer pain. There are a number of possibilities that David would have to explore with his customers.
