I’m working on a computer science writing question and need an explanation to help me study.Business Process and Functional ModelingOverviewAdvanced 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 more than 50 regional offices in the 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 the 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 immediately starts searching outside.
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 or 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 (such as, 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 or 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.InstructionsWrite a 4–5 page paper in which you:Create a use case diagram to include at least three actors for the system described in this case through the use of graphical tools in Microsoft Word or Visio, or an open-source alternative such as Dia.
