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.
