A large, fast-food chain unveiled a new touch screen register for its franchises. Each cashier was assigned a user id and password combination to log in to the register. The system allowed the incorrect password to be entered four (4) times before the register would lock and require a manager to unlock it with a key card. To prevent unauthorized access, the registers would lock after three (3) minutes if the screen was not touched. When the register locked, only the cashier who was logged in prior to it locking could unlock it without a system restart. 

After a few days in operation, restaurant managers started complaining about the amount of time they were spending unlocking the registers. Some cashiers were forgetting their user Id and password, so other cashiers would log in for them. It also seemed that the button layout made it easy for the cashiers to key in the incorrect password. The managers also complained that cashiers would leave for a break or end their shift and forget to log out of the locked register. The managers would have to reboot the system, a three to five (3-5) minute process in order for the next cashier to log in. Additionally, managers noticed that grease was building up on the touch screens, making them less responsive.

Write a five to eight (5-8) page paper in which you:  

1. Analyze      the new system and determine the design issues with this new system.
2. Describe      how you would correct the design issues with the system to make the      restaurant managers happy.
3. Create      a design plan that: 

1. Lists       and explains the tasks associated with improving this interface. 
2. Contains       at least six (6) tasks.
3. Includes       realistic time estimates for each task to be completed.
4. Analyzes       the development of the system in your plan.
5. Analyzes       the testing of the system in your plan.
6. Analyzes       the implementation of the system in your plan.  
7. Examine      how this system balanced security and usability, and explain the      challenges of incorporating system security and system usability into a design.
8. Suggest      changes that could be made to the security of this system to still meet      security objectives but make the system more usable.
9. Use      Microsoft Visio or an open source alternative, Dia, to create a graphical      representation of your proposed interface. Note: The graphically depicted      solution is not included in the required page length.
10. Use at      least three (3) quality resources in this assignment. Note: Wikipedia and      similar Websites do not qualify as quality resources.
