Assignment 3: Design with UML
Due Week 7 and worth 120 points
Advanced Business Systems (ABS) is a consulting and staffing
company providing specialized staffing and consulting services to
clients in a variety of different industries. It has offices in
major U.S. metro areas and has ongoing relationships with Fortune
500 companies. Its areas of services range from software
development and network engineering to geo-information systems. It
has fifty (50) plus regional offices in U.S. and five (5) offices
in Canada. It plans to expand to other countries in the future.
When an ABS client company determines that it will need a
contractor or temporary professional, it issues a staffing request
against the contract it had previously negotiated with ABS. The
contract manager in ABS reviews the staff request and ensures that
the request is valid with its current contract with its client from
the database.
If the request is not valid, the contract manager sends the
staffing request back to the client and explains the reasons and
asks for the need for starting a new contract.
If the request is valid, the contract manager will start
recruiting requests by putting the request into its staffing
database. The staffing request is then sent to ABS placement
department.
In the placement department, the placement specialists will check the job requirements and candidates qualifications.
If there is a qualified candidate, the specialist will notify
the candidate and put a note in the database.
If a qualified candidate cannot be found or not immediately
available, the specialist notifies contract managers and recruiting
department; the recruiting department starts search outside
immediately.
The recruiting department normally has thirty (30) days to find
an outside candidate and send the qualified candidates to the
placement department to review. If an internal qualified candidate
is confirmed with his / her availability, the confirmation will be
sent to the arrangement department. In the arrangement department,
the candidate works with the specialists to further confirm the
placement details, such as starting date, location, compensation
(e.g., per diem), and travel arrangement. The final confirmation
will be sent to the client along with a billing schedule. If the
client agrees with the arrangement, he/she acknowledges the
arrangement with contract managers in the contract department. The
contract manager then puts a memo into its database and closes the
request.
Note: You may create and / or assume all necessary
assumptions needed for the completion of this assignment.
Write a three to four (3-4) page paper in which you:
Create a package diagram of the problem domain layer using the
communication diagrams and the CRUDE matrix through the use of
graphical tools in Microsoft Word or Visio, or an open source
alternative such as Dia. Note: The graphically depicted solution is
not included in the required page length.
Perform and explain the verification and validation
walk-through of the package diagram.
Create a set of invariants for attributes and relationships
and add them to the CRC cards for each class in the structural
model using Object Constraint Language (OCL).
List the classes in the structure model. Choose one (1) class
and create a contract for each method in that class. Note: Be sure
to use OCL to specify the preconditions and the post conditions.
Create a method specification for each method using both
structured English and activity diagram for the algorithm
specification through the use of graphical tools in Microsoft Word
or Visio, or an open source alternative such as Dia. Note: The
graphically depicted solution is not included in the required page
length.
Use at least two (2) quality resources in this assignment.
Note: Wikipedia and similar Websites do not qualify as quality
resources.
Your assignment must follow these formatting requirements:
This course requires use of new Strayer Writing Standards (SWS).
The format is different from other Strayer University courses.
Please take a moment to review the SWS documentation for details.
Be typed, double spaced, using Times New Roman font (size
12), with one-inch margins on all sides; citations and references
must follow SWS 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 Visio or Dia. 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:
Determine the steps and principles of design modeling with UML.
Document and describe the different state of objects
throughout the life cycle.
Use technology and information resources to research issues
in procuring and designing project requirements.
Write clearly and concisely about project requirements and
design topics using proper writing mechanics and technical style
conventions.
