Assignment 1
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 50 plus regional offices in U.S. and five 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 candidate's 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 the recruiting department; the recruiting department starts searching outside immediately.
The recruiting department normally has 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.

Assignment 2
Refer to the functional model you verified and validated for ABS assignment to complete this assignment.
Based on your performance, ABS management was so satisfied that it wants you to develop both the structural and behavior models. This way, ABS can fully understand both the interaction that would take place between the users and the system, and the system itself in greater detail.
Note: You may create and / or assume all necessary assumptions needed for the completion of this assignment.
Write a four to five page paper in which you:
1. Create Class-Responsibility-Collaboration (CRC) cards and a class diagram based on the functional models 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.
2. Identify each use case in the functional model and create a sequence and communication diagram for each scenario of each use case identified 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.
3. Create a behavioral state machine for each of the complex classes in the class diagram.
4. Perform a CRUDE analysis to show the interactivity of the objects in the system.
5. Perform a verification and validation walk-through of each:
1. Functional model
2. Structural model
3. Behavioral model
6. Revise the requirements document created in Assignment 1 with additional information found in this assignment and document the assumptions.
7. Use at least three 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.
