When an employee creates a purchase requisition, his/her supervisor must approve it. When an approved purchase requisition reaches the purchasing department, a purchasing agent evaluates the record, and then performs one of the following steps: Rejects the requisition Creates a request for quotation to receive bids for the purchase Creates a purchase order from the requisition The purchase requisition contains name, total price, quantity, and purpose (assume that the requisition is for one type of items). Depending on the price, additional approval may be need as described below. If the total price is $250 or less, no further approval is needed, and the requisition is routed to the purchasing department. If the total price exceeds $250 but is less than $1,000, the requisition then requires the approval of the department manager (after the approval of the supervisor) before it can be routed to the purchasing department. If the total price exceeds $1,000 but is less than $5,000, the requisition then requires the approval of a vice president (after the approval of the department manager) before it can be routed to the purchasing department. If the total price exceeds $5,000, the requisition then requires the approval of the chief financial officer (after the approval of the vice president) before it can be routed to the purchasing department
