As product managers we are always being told that we need to better  understand our customers. We believe that if we were to truly understand  them, then we would know how to offer them the products that they want,  when they want them, and where they want them. In the world of retail  products this is especially true. It turns out that there is a special  type of product manager who just may have figured out a new product development definition that allows them to do all of these things at once. Who is this person you ask? Why it’s a pop-up product manager.
