Draw a BPMN diagram that models the reimbursement process described below. Use one swimlane for each of the three actors in the process.

The travel reimbursement process for employees of West Nile Valley University involves three different actors: the employee, the employee's departmental sec- retary, and the treasurer's office. First, the employee has to gather and prepare all of the receipts the univer- sity requires for reimbursement. At the same time, she completes the official reimbursement form. She then submits both the receipts and the form to the depart- mental secretary. If something on the form is incorrect, the secretary returns the form to the employee for cor- rection. If the form is correct, the secretary prepares shown is not correct, the employee must indicate that this is the case. If the amount shown is correct, then the treasurer's office sends the reimbursement to the employee's bank, completing the process.
