You are required to review the narrative process below to construct a process map.

The sales process begins with a customer contacting the sales department by telephone, mail, or in person.

The sales department records the essential details on a sales order.

This information will later trigger many tasks, but for the moment is filed pending credit approval.

To provide independence to the credit authorization process, the credit department is organizationally and physically segregated from the sales department.

When credit is approved, the sales department clerk pulls the various copies of the sales orders from the pending file and releases them to the billing, warehouse, and shipping departments.

The customer order and credit approval are then placed in the open order file.

The next step is to ship the merchandise, which should be done as soon after credit approval as possible.

The warehouse clerk receives the stock release copy of the sales order and uses this to locate the inventory.

The inventory and stock release are then sent to the shipping department.

Finally, the warehouse clerk records the inventory reduction in the stock records.

The shipping clerk reconciles the products received from the warehouse with the shipping notice copy of the sales order received earlier.

As discussed previously, this reconciliation is an important control point, which ensures that the firm sends the correct products and quantities to the customer.

When the order is correct, a bill of lading is prepared, and the products are packaged and shipped via common carrier to the customer.

The clerk then enters the transaction into the shipping log and sends the shipping notice to the billing department
