Vision Statement

Problem Description

Coffee shops are often busy in the morning hours with people wanting coffee early in the morning on their way to work. Due to this, many coffee shops become overcrowded and overwhelmed with the amount of incoming orders. The problem with this is that some customers become irritated with the wait time and end up leaving resulting in a loss of profit for the coffee shops. With this problem in hand, the company requires a system that can allow customers to place orders ahead of time, as well as a subscription-based order system.
