Wiltex Research is a company that performs energy research on a contract basis for major oil and chemical companies. The following narrative describes the process to acquire materials for research projects. A project manager determines the materials needed for a project and purchases them from a vendor. The project manager completes a purchase order for each piece of materials. A catalogue price is used, or the vendor is contacted by telephone to determine the price. The purchase order has an original and two copies (Copy #1 and Copy #2). The project manager sends the purchase order to the project supervisor for approval/disapproval. The project supervisor writes "approved" or "disapproved" on the purchase order, signs it, and returns it to the project manager. The project manager sends the original copy of approved purchase orders to the vendor; sends Copy #1 to the accounting clerk; and files Copy #2 in a permanent project file (ordered numerically by project number). Disapproved purchase orders are thrown in the garbage can by the project manager. The accounting clerk files Copy #1 in a temporary file (numeric by PO#). The project manager receives and inspects materials sent from the vendor and compares them to the packing slip. The packing slip is sent to the accounting clerk as evidence that the materials have been received. The accounting clerk matches the packing slip with the Copy #1 of the purchase order and prepares a check (which has an original and one copy). The check is attached to the packing slip and Copy #1 of the purchase order is sent to the project supervisor for a signature. Once signed, the entire set of documents is returned to the accounting clerk who sends the original copy of the check to the vendor, and files the copy of the check with the supporting documentation attached to it in a permanent file (ordered numerically by check number). Required: Prepare a document flowchart and a BPMN diagram in good form for this part of Wiltex Research.
