A fast-food restaurant receives on average 1200 customers per day (between 10:00 and 22:00). During peak times (12:00-15:00 and 18:00-21:00), the restaurant receives around 900 customers in total, and 90 customers can be found in the restaurant (on average) at a given point in time.

In an order-to-cash process, which of the following situations represent a waste of type Defect? -The customer sends back some of the products they received because they did not match what had been agreed upon in the PO. The supplier is obliged to pay for transportation of the products back to their warehouse and has to re-send the correct products -Three days after sending the Purchase Order (PO), the customer asks that the PO be cancelled after discovering that the ordered products are no longer needed. The cancellation request is accepted since the ordered products have not been dispatched yet -The PO is received on a Monday. On that day the workload is very high and it is not possible to confirm if the products can be delivered on the date requested by the customer. The PO is put on hold until Wednesday and only then a response is sent to the customer. -An invoice is received but the amounts shown in the invoice do not match the ones in the corresponding PO.
