This document provides instructions for a BSA 411 week 4 individual assignment. Students are asked to create a 1-page mock-up of a user interface based on their previous 3 individual assignments, showing how a user interacts and navigates the system. They then need to write a 1-page paper describing how their user interface satisfies quality requirements for a WebApp in terms of usability, functionality, reliability, efficiency, maintainability, security, and scalability. The assignment should be submitted through the assignment files tab.
