Draw a BPMN (Business Process Model and Notation) diagram that models the employees reimbursement process described below.

Employees of West Nile Valley University have to follow a specific procedure to get reimbursed for travel they undertake on behalf of the university. First, they have to gather and prepare all of the receipts the university requires for reimbursement. At the same time, they complete the official reimbursement form. They then submit both the receipts and the form to their departmental secretary. If something on the form is incorrect, the secretary returns the form to the employee for correction. If the form is correct, then the employee is asked to review the reimbursement amounts, which are determined by an analysis of the reimbursement request. If the amount shown is not correct, the employee must indicate that this is the case. If the amount shown is correct, then the employees responsibilities for reimbursement are complete.
