Vicki just opened her new cupcake store. She knew from conducting online research what the most popular cupcake was and planned her menu accordingly. When she opened her doors there was a small trickle of steady customers for a month, but not the anticipated flood she was hoping for. What mistake did Vicki make

She failed to research on the general demand for cupcakes.
