Using any BPMN modeling tools, please model the following process: University faculty members often travel to conferences to present research papers. The associated expenses are reimbursed through a business process called Travel Expense Reimbursement. The travel reimbursement process occurs after the faculty returns from a trip and starts with the faculty member filling out an expense form. The faculty member then submits the completed form to the department chair for review and approval. The department chair can make one of three decisions regarding the reimbursement request; he can reject the request as a non reimbursable expense which ends to process, he can return it to the faculty member for corrections, or he can approve it. If the expenses are approved, the department chair sends the form to accounts payable for check processing and distribute the check.
