MODELING EXERCISE 3 INSTRUCTIONS
Overview
For this modeling exercise, you will re-visit the scenario given in the Modeling Exercise 2
Instructions document and consider the following, additional information.
Materials Required
To complete this deliverable, you will need the following materials
• This document
• Microsoft Word
• LucidChart.com, http://draw.io, StarUML (http://staruml.io), PlantUML
(http://plantuml.com), or Microsoft Visio
Scenario
During your first visit to the restaurant, you conducted interviews with several people to better
understand their responsibilities and job functions. The following descriptions are from the notes
taken during that initial visit.
Owner: The owner created the Mom & Pop Pizza 8 years ago and is now looking at opening a
second store by year 10. In the planning for this, his family has convinced him that franchising
the operation could be very successful. One large barrier to franchising is that of a consistent
repeatable process. Therefore the owner has decided to contact you to design an enterprise IT
system that would be scalable to support a multi-state franchise. That being said, the owner has
no vision of what this system would look like. He is a pizza chef, not an IT consultant/designer.
Manager: The manager runs the day to day operations, as well as the hiring/firing/training; the
manager is required to schedule all employees. Finally, the manager is responsible for
inventorying and ordering the supplies needed. He orders supplies once a week.
Hostess: The hostess greets customers and takes reservations over the phone. The hostess also
takes delivery/takeout orders and arranges for delivery drivers. The hostess also seats customers
when tables become available.
Waiter: The waiter takes customer orders, delivers orders to one of the cooks, and takes drinks
and food to the customers. The waiter also delivers the bill to the customer, takes money (or
credit cards) to the hostess for processing, and returns change (or credit card receipt for signing).
Cook: The cook receives orders from the wait staff and prepares the customer’s selections.
Food Prep: The food prep prepares sauces and dough for cook’s use; he/she also prepares salad
and all other side dishes.
Busboy: The busboy cleans tables after customers leave, preparing the tables for the next
customers. The busboy also delivers dirty dishes to the dishwasher.

Accountant: The owner has traditionally filled the accountant role. He tallies receipts at the end
of the day and makes bank deposits. He pays all the bills on a bi-weekly basis. He accounts for
all employee hours, and every two weeks, he prepares payroll checks. He files all IRS and tax
documentation and manages the health and benefits plans of the employees.
Instructions
With a revised business process in hand, it is time to begin identifying the key ways that you
anticipate the users will interact with M&P PIES. To do that, you will create a use-case diagram
and five use-case scenarios to model those interactions. It is important to note that a use case
reflects the direct interaction that a user will have with the system, not an activity that takes place
outside the system. For example, we would not want to create a use case for preparation of
sauces, unless we were designing the system to have some role in that activity. For this third
exercise, develop a use-case diagram showing all actors and use cases for the proposed, to-be
system, and then choose five use cases from your use-case diagram and write a detailed, use case
scenario for each one. You will need to refer back to the to-be process description given in
Modeling Exercise 2 instructions, as well as the notes provided above from the user interviews.
As you complete this exercise, keep the following in mind:

Refer to the Modeling Exercise grading rubric before you begin this exercise.
Even though we are now modeling the use cases for a technology system, the use cases
should still avoid references to any specific technology.
The purpose of this diagram is to visually communicate with the client the way we expect
them to use the new system. As such, your diagram should be easy to read for a nontechnical person, follow correct UML syntax for activity diagrams (see the UML
textbook), and include a proper title and legend (you will need to draw the legend
manually, using the unique shapes used in the diagram along with a short textual
description of what each shape represents).
Be sure to model your use cases such that they represent actual interactions with the
system and not activities that would occur outside the context of the new system.
Don’t forget to include a system boundary in your use-case diagram.
There are no, set-in-stone solutions for this exercise. Just as in the real world, there are no
off-the-shelf solutions for every IT challenge. It is not our intention to limit your creative
knowledge designs.
The instructor may make suggestions or add additional requirements in the weekly
announcements for each modeling exercise, so be sure to heed those suggestions as you
prepare your models, or you may lose points.

Textbook Readings
Motiwalla & Thompson: ch. 4
These arethe results from Model EX 2
22 (29.33%)
Points Range:22 (29.33%) – 24 (32%)
The model accurately and logically reflects the requirements given.
Feedback:
The model did not properly model the fact that bus boy notifications need to be handled in an automated
fashion. At minimum, there should be an action drawn in a swim lane for the M&P PIES system that takes care
of the automated bus boy notifications at some point in the process. (2)
22 (29.33%) – 24 (32%)
The model completely represents all of the requirements in the given scenario.
Feedback:
The model did not model the fact that reviewing and updating recipes need to handled in an automated fashion.
At minimum, there should be an action drawn in a swim lane for the M&P PIES system that takes care of the
recipe management at some point in the process. (2)
Incorrect UML symbols are used and UML modeling syntax is incorrectly applied.
Feedback:
One and only one terminal node should be included in each activity diagram. (1) Decision nodes should be
used to model the possibility that the process will split into one of at least two mutually exclusive paths. As
such, every decision node should have at least two out paths. There was at least one decision node that had
only one out path. (2) At least one activity on the diagram did not have any “outflows”. Recall that in an Activity
diagram, all activities should have at least one input and exactly one output. (2)
Models present a mostly professional look and are somewhat understandable.
Feedback:
Please ensure that all portions of the diagram are completed using one of the approved software tools. Handdrawn portions are simply not professional and will not be given full credit in this course. (1)
All modeling assumptions are clearly stated; Drawing is titled properly and legends are used.
