Because a product consists of more than just packaging or a product idea, it is advisable to have the physical product assessed and tested by the intended target group. After all, you can tell a good story and entice consumers to make a purchase with an attractive design, but that is only the beginning.
Does the product meet the customer's needs, fit the brand, and live up to the expectations created by the concept idea and packaging? Will people buy the product again after trying or tasting it?
