The document describes a case study involving a new touch screen register system implemented in a large fast food chain. The system had several design issues, including allowing incorrect passwords to be entered multiple times before locking, locking after only a few minutes of inactivity, and only allowing the logged in cashier to unlock a locked register. These issues led to managers spending significant time unlocking registers for cashiers who forgot passwords or left without logging out. The document outlines requirements for a paper to analyze the system's design issues, propose corrections, and create a design plan with tasks, time estimates, and diagrams to address the issues while balancing security and usability.
