System Diagrams & Visualization
Example - Fast Food Restaurant
• Create Data Flow and UML Diagrams to show the process of
ordering
food at a Fast-Food Restaurant.
• Who are the players in the process (customer, clerk, cooks...)?
• What automated systems are used in the process?
• What activities work well, and which do not?
• What changes have you noticed over the years to make the
processes better
(for the customer and for the business)?
• What changes would you make to improve the processes and
performance?
• What data can be stored and used to analyze the performance
of the systems
(i.e. how can Analytics be used)?

The Use Case diagram is a high-level diagram that
identifies an Actor’s interactions with a system. It is not
meant to get into details. Details are covered in other
types of diagrams.
A Customer places an order with a Cashier (or Kiosk) and
then pays the Cashier (or via the Kiosk).
The Cashier then delivers the order to the Customer.
Notice this does not try to show the different between a
drive-in transaction versus a walk-in;
Or a person or a kiosk (like Taco Bell or McDonalds)

The Activity diagram provides details on
the activities of a process using “Swim
Lanes”. In this case, the customer places
the order with the Cashier who enters
the order and receives details from the
Order system and enters the payment
and receives details from the Payment
system.
Note in this diagram that the actual
order is not transmitted to the Cook until
the transactions are processed.
How might this diagram be different if
the customer used a Kiosk rather than a
Cashier?

The Sequence diagram shows the
sequence of activities. The Customer
places an order as a list of items
(with exceptions) and the Cashier
enters them into the Order system.
The order is displayed back.
The Customer makes a payment

6. which triggers the order to the Cook
and to the Payment system. The
payment is displayed back, and the
Cashier refunds any overpayment.
The Cook stages the order items, and
the Cashier gives them to the
Customer when complete.
Notice bars that extend down and
represent the approximate time
needed to satisfy an action. The X’s
at the bottom represent the last
actions. These just happen to end at
the same time.

The Statechart diagram shows
states (i.e. waiting for something)
within the process.
Once the Customer places the

11. order, it is ‘pending’ approval
(awaiting cashier data entry and
system response). Once the
Customer is told the cost, it is
‘pending’ customer acceptance
and payment. Once payment is
made, it is ‘pending’ acceptance
by the cashier or card processor.
Etc.
Notice the loops indicating that all
items are not finished cooking at
the same time and are bagged as
they are ready and discovered by
the Cashier.

14. Policy Practice PowerPoint Presentation
The purpose of this assignment is to give you the opportunity to
learn about the process of how proposed legislation becomes a
law and the political forces involved. You will also have the
opportunity to engage in policy practice by persuading your
classmates to take action on behalf of the bill.
1. Identify a bill or amendment (no resolutions) that advances
social well-being and is being considered by your state
legislature. (I LIVE IN NEW YORK!) You may want to identify
more than one bill in case your first choice is killed early. You
may want to choose a state bill that is related to your
comprehensive assignment (paper).Presentations submitted on
federal legislation will receive a 0 for the assignment.
2. Interview at least one person who is committed to the bill (a
stakeholder). This may be the bill’s sponsor, a committee staff
person, an aide to the legislator, a lobbyist, a state agency
bureaucrat, a beneficiary of the bill, a community or state
leader, etc. NOTE: Do not just email a list of the questi ons to
someone and expect her/him to respond. Interview a real person,
either face-to-face, Skype, or on the telephone. Failure to
complete the interview will result in a 0 for the assignment. In
addition to referring to and correctly citing the interview , you
will provide the instructor a report indicating your bill choice
and stakeholder. (see below)For this portion, please include the
name of the stakeholder, their e-mail, contact number, etc. for
the instructor to believe the interview took place in New York.
3. Use a variety of source-types such as academic research
articles, news articles, interviews with stakeholders,
government reports, etc.
4. Create a PowerPoint presentation that discusses the issue

15. below (no more than 10 slides) with a short, audio discussion
accompanying each slide. You may use the following bullet
points in your presentation, but please also refer to the grading
rubric for this assignment. The presentation should last no more
than 10 minutes. Upload your presentation to your Moodle
course page and the Social Forum so that it can be viewed by
the class. Include this information:
a. Basic description of bill and its purpose (what problem does
it address?)
b. What cultural values underpin the bill (family, work, self-
reliance, etc.) and how the problem is understood?
c. Who is affected, directly and indirectly? In what way(s) will
the bill affect social justice, oppression and discrimination
issues?
d. Political pressure for/against the bill.
e. Role of service recipients in the development and/or passage
of the bill.
f. Costs of implementation, who will implement, and timeframe
g. Analysis of the policy’s development (see rubric)
h. Note: The final step of this assignment is to engage your
classmates in supporting your bill, much as you would in actual
policy practice. You may be as creative as you like. Consider
asking them to identify their legislators, write a letter to the
editor of a newspaper, create a petition on change.org, create a
talking point on the signature to their email, etc.
Tips for Creating Good PowerPoints
· Keep it simple.

16. · Use plenty of white space
· Use text minimally. Follow “general rule” of no more than 6
lines of text, with no more than 6 words per line (this is
approximate, not exact)
· Make it visually engaging by using graphics, but don’t overdo
it by making it too “busy.”
· Use the same font on each slide
· Use animations sparingly

6th edition formatting, click here.

***** The last slide of the power point should be

Policy Practice Power Point Presentation - New York State Bill
- For this assignment I have to complete a power point hitting
points A through G of the attached file (assignment guideline).
Over the PowerPoint, I will be recording my voice reading the
actual research paper; discussing the information on the
PowerPoint. The tricky part is that for this assignment is that
the professor has to believe I interviewed a stakeholder of the
policy. I need to include his/her contact information in the
slides and a little briefing of our "conversation" during the
"interview". If you have any questions, feel free to reach out.

21. Systems Diagrams and Visualization Project
Create the following UML diagrams to visualize the process of
completing the IT project from the previous
exercise (providing IT services for a new building):
• Use Case diagram
• Activity diagram
• Communications diagram
• Data Flow diagram
Assume the following basic processes:
1. Procurement of all resources.
2. Setup of PCs and network servers.
3. Deployment and Testing of resources to the IT Area/Office.
4. Deployment and Testing of resources to the Administrative
Area.
5. Deployment and Testing of resources to the Conference
Room.
6. Deployment and Testing of resources to the Meeting Room.
7. Deployment and Testing of resources to the Individual
Offices.

22. 8. Deployment and Testing of resources to the Computer Labs.
9. Testing of all Other Locations.
• Create a Use Case diagram to show all actors and the basic
processes above
o Procurement, Setup, Deployment & testing of each major
location.
• Create an Activity diagram to show the deployment and
testing of resources into the Computer Labs
o Network connectivity testing requires interaction between the
PC and Network Specialist
o Projector connectivity testing requires interaction between the
PC and AV Specialist.
• Create a Communications diagram to show collaboration
between the PC Specialist, the Network Specialist
and the AV Specialist during deployment and testing of
resources into the Computer Labs.
o If network connectivity issues arise, the PC Specialist will
communicate with the Network
Specialist.
o If projector connectivity issues arise, the PC Specialist will
communicate with the AV Specialist.

23. • Create a Data Flow diagram to show the Procurement of all
resources, based on this additional information:
o The PC Specialist enters all purchases into the Purchase
Application system once the resources
are purchased.
o The PC Specialists closes all purchases in the Purchase
Application system once the resources
are received.
