Haya noticed that male college students needed to dress up for presentations but never seemed to have any ties, or at least not very nice ones. She decided she was going to set up a tie store on her campus and offer sports-themed ties as well as solid-colored ties in her school colors. She can put an announcement on the school's monitors that would display in the dining halls and student union. The supplier of Haya's ties is downstream in her supply chain. Discuss?
