Case Study 3: Security
Due
Week 7 and worth 100 points
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:
a.
Lists
and explains the tasks associated with improving this interface.
b.
Contains
at least six (6) tasks.
c.
Includes
realistic time estimates for each task to be completed.
d.
Analyzes
the development of the system in your plan.
e.
Analyzes
the testing of the system in your plan.
f.
Analyzes
the implementation of the system in your plan.
4. Examine how this system balanced
security and usability, and explain the challenges of incorporating system
security and system usability into a design.
5. Suggest changes that could be
made to the security of this system to still meet security objectives but make
the system more usable.
6. 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.
7. Use at least three (3) quality
resources in this assignment. Note: Wikipedia and similar Websites do not
qualify as quality resources.
Your
assignment must follow these formatting requirements:
Be typed, double
spaced, using Times New Roman font (size 12), with one-inch margins on all
sides; citations and references must follow APA or school-specific format.
Check with your professor for any additional instructions.
Include a cover page
containing the title of the assignment, the student’s name, the professor’s
name, the course title, and the date. The cover page and the reference page are
not included in the required assignment page length.
Include charts or diagrams created in Excel, Visio, MS Project, or one of their
equivalents such as Open Project, Dia, and OpenOffice. The completed diagrams/charts
must be imported into the Word document before the paper is submitted.
The
specific course learning outcomes associated with this assignment are:
8.
Describe the usability properties of interactive systems.
9.
Describe the inherent design issues across HCI environments
10.
Develop an
interface `
11.
Use technology
and information resources to research issues in human-computer interaction.
12.
Write clearly
and concisely about HCI topics using proper writing mechanics and technical style
conventions.
